Access to programs, data and functions is protected in a user-oriented hierarchical system of 7 access levels.

• 3 password levels (protection levels 1 to 3) for machine manufacturers and end users, and

• 4 keyswitch positions (protection levels 4 to 7) for end users (keyswitch positions can also be evaluated via PLC)

SINUMERIK CNCs thus have a multistage concept for controlling access rights.

Protection level 1 has the highest access rights and protection level 7 the lowest. A higher protection level automatically includes all

protection levels below it.

Access rights for protection levels 1 to 3 are preprogrammed by Siemens (default setting). An entered password has priority over

a keyswitch position, and machine manufacturers or end users can change access rights for protection levels 4 through 7.

Subprograms can be completely protected against unauthorized reading and display.

Alarms and messages

• Alarms and messages:

All messages and alarms are output separately on the operator panel in plain text with date and time as well as the appropriate

symbol for the delete criterion. All alarms are saved in an alarm log that can be configured according to size.

• Alarms and messages in the part program:

Messages can be programmed to provide the user with information about the current machining situation during program execu-

tion. Message texts may be up to 124 characters long, and are displayed in 2 lines (2 62 characters). The contents of variables

can also be displayed in message texts.

Example 1:

N10 G1 F2000 B=33.333

N15 MSG ("Rotary table position:" "$AA_IW[B]" "Degrees")

Display in message line following traversal of block N10

Rotary table position: 33.333 degrees

Example 2:

N20 MSG ("Check" "$AA_IW[X]" "X position!")

Display: Check ... X position!

In addition to programming messages, alarms can also be set in a CNC program. An alarm always goes hand in hand with a

response from the CNC according to the alarm category. The alarm text must be configured, alarm numbers 65000 to 67999 are

available. A description of the responses to the various alarms can be found in the Commissioning Manual.

Example 3:

N100 SETAL (65001) Effect:

Display interlocking CNC start

Deletion: with reset

• Alarms and messages from the PLC:

Machine-specific alarms and messages can be displayed directly from the PLC program in plain text. Messages comprise status

messages and error messages. In the case of status messages, the display is immediately deleted when the condition is no longer

active, error messages must be acknowledged. User-specific alarm numbers from 40000 to 89999 can be assigned to general,

channel-specific, axis-specific and spindle-specific user alarms and messages. The response of the CNC to alarms or messages

can be configured. The configured alarm and message texts are saved in application-specific text files.

• Specific evaluation of alarms:

A channel-specific signal can be used to decide whether other channels may continue to be used when an alarm is issued.

Analog value control

System variable $A_OUTA(n) enables values from up to 8 analog outputs to be directly entered in the part program. The value

specified by the NCK can be changed by the PLC before it is output to the hardware of a SIMATIC DP ET 200 analog module.

The hardware outputs are written in the interpolation cycle.

Asynchronous subprograms ASUB

An asynchronous subprogram is a CNC program which can be started in response to an external event (e.g. a digital input) or from

the PLC. Inputs are allocated to subprograms and activated by programming SETINT.

If the relevant event occurs, the CNC block currently being processed is immediately interrupted. The CNC program can be con-

tinued later at the point of interruption. Multiple asynchronous subprograms must be assigned different priorities PRIO so that they

can be processed in a certain order. Asynchronous subprograms can be disabled and re-enabled in the CNC program

(DISABLE/ENABLE).

 Interrupt routines with fast retraction from the contour

Auto Servo Tuning AST

Auto Servo Tuning AST automates the process of adapting parameters to the control equipment, which controls the axes of a CNC

machine. The parameters are adapted according to the frequency response measurement of the machine dynamics. One of the

benefits of Auto Servo Tuning AST is that it facilitates the measuring process.

The axis control loops are individually optimized according to the target parameters selected by the user for an adaptive strategy.

In a second step, the control loop parameter settings are adjusted for axes that are identified as being involved in an interpolation

path, with the result that the correct dynamic response is obtained for all axes. This adaptation ensures coordinated movement of all

the axes along the interpolation path.

 Call Auto Servo Tuning from part program AST call

Auxiliary function output

Auxiliary function output informs the PLC when the part program wants the PLC to handle certain machine switching operations.

This is accomplished by transferring the appropriate auxiliary functions and their parameters to the PLC interface. The transferred

values and signals must be processed by the PLC user program.

The following functions can be transferred to the PLC:

• Tool selection T

• Tool offset D/DL

• Feedrate F/FA

• Spindle speed S

• H functions

• M functions

Auxiliary function output may be carried out either with velocity reduction and PLC acknowledgement up to the next block, or before

and during travel without velocity reduction and without block change delay. Following blocks are then traversed without a time-out.

Axes, coupled motion

When a defined leading axis moves, the coupled-motion axes (following axes) assigned to it travel the traverse paths derived from

the leading axis, taking into account a coupling factor (setpoint coupling). Together, the leading axis and the following axes form a

coupled-axis grouping.

Definition and activation of a coupled-axis grouping take place simultaneously with the modal instruction TRAILON. A coupled-axis

grouping can consist of any desired combinations of linear and rotary axes. A coupled-motion axis can be assigned up to 2 leading

axes (in different coupled-axis groupings). A simulated axis can also be defined as the leading axis, in which case the real axis

actually does the traveling, taking into account the coupling factor. Another application for coupled-motion axes is the use of

2 coupled-axis groupings to machine the 2 sides of a workpiece.

Axis container

On rotary indexing machines/multi-spindle machines, the axes holding the workpiece move from one machining unit to the next.

Since the machining units are handled through different NCU channels, the axes holding the workpiece must be dynamically

reassigned to the corresponding NCU channel if there is a change in station/position. Axis containers are used for this purpose.

Only one workpiece clamping axis/spindle is active on the local machining unit at a time. The axis container combines the possible

connections to all clamping axes/spindles, of which only one is active at a time for the machining unit.

The available axes that are defined in the axis container can be changed by shifting the entries in the axis container. Shifting can be

triggered by the part program or synchronized actions: Keyword AXCTSWE(CT1).

Axis data output via PROFIBUS, Run MyCC /ADAS

Option; order code N07

Article No.: 6FC5800-0AN07-0YB0

SINUMERIK Integrate Run MyCC /ADAS enables axis and spindle data to be output to a special PROFIBUS or PROFINET device

module. This function can be used, for example, for process or machine monitoring functions in real time outside the CNC.

The required axis and signal type are selected by transferring a selection command (length: 8 bytes) to the CNC. SINUMERIK

Integrate Run MyCC /ADAS in the NC kernel then sends up to 30 axis data items (of 4 bytes each) to the slave in each PROFIBUS

cycle.

The transfer cycle can be equal to the position controller cycle, or a multiple thereof. Consistent receipt of data from each cycle can

be guaranteed only when the slave is operating in isochronous mode (or with PROFINET IRT).

Axis limitation from the PLC

The preactivation of protection areas with specification of a position offset is programmed in the part program. You can put the

preactivated protection areas into effect in the PLC user program via the PLC interface. As a result, the relevant protection area is

activated, for example, before a tool probe is swiveled into position in the working area, to see whether the tool or a workpiece is in

the path of the swiveling part.

The PLC can put another axis limitation into effect by activating the 2nd software limit switch via a PLC interface signal. This reduction

of the working area may become necessary, for example, when a tailstock is swiveled into position.

The change is immediately effective, and the 1st software limit switch plus/minus is no longer valid.

 Protection areas 2D/3D

Axis/spindle replacement

An axis/a spindle is permanently assigned to a specific channel via machine data. The axis/spindle replacement function can be

used to release an axis/a spindle (RELEASE) and to assign it to another channel (GET), i.e. to replace the axis/spindle. The relevant

axes/spindles are determined via machine data.

Backlash compensation

During power transmission between a moving machine part and its drive (e.g. ball screw), there is normally a small amount of back-

lash because setting mechanical parts so that they are completely free of backlash would result in too much machine wear. In the

case of axes/spindles with indirect measuring systems, mechanical backlash results in a corruption of the traversing path. For

example, when the direction of movement is reversed, an axis will travel too much or too little by the amount of the backlash.

To compensate for backlash, the axis-specific actual value is corrected by the amount of the backlash every time the axis/spindle

reverses its direction of movement. If a 2nd measuring system is available, the relevant backlash on reversal must be entered for

each of the two measuring systems.

Backlash compensation is always active in all modes following reference point approach.

The block search function allows any point in the part program to be selected where machining should start or be continued. The

function is provided for the purpose of testing part programs or to continue machining after it was canceled. Cascaded block search

is also possible.

Search variants:

• With calculation on the contour

During the block search, the same calculations are performed as in normal program operation. The target block is then traversed

true-to-contour until the end position is reached. Using this function it is possible to approach the contour again from any situation.

• With calculation at block end point

This function allows a target position to be approached (such as tool change position). All calculations are also executed here as

during normal program operation. The end point of the target block or the next programmed position is approached based on the

interpolation valid in the target block.

• Without calculation

This method enables high-speed searches in the main program. No calculations are carried out during the search. The internal

control values remain the same as before the block search.

• External block search without calculation

Path CP, or as a Point-to-Point PTP motion. With PTP, the shortest way to reach the end point is with activated TRAORI transformation.

PTP generates a linear interpolation in the axis space of the machine axis.

By smoothing from PTP to CP movement, it is possible to switch from fast infeed to a mounting or positioning movement with optimum

timing. PTP travel does not result in an axis overload when traveling through a singularity, such as changing an arm position during

handling. PTP travel is also possible in the JOG CNC operating mode and does not require Cartesian positions (e.g. from CAD

systems) to be converted into machine axis values.

Cartesian PTP travel is also used for cylindrical grinding machines with an inclined axis: With active transformation, the infeed axis

can be moved either according to Cartesian coordinates or at the angle of the inclined axis.

Cartesian travel to fixed stop, Run MyCC /FXSC

Option; order code N38

Article No.: 6FC5800-0AN38-0YB0

SINUMERIK Integrate Run MyCC /FXSC cartesian travel to fixed stop is used as a substitute for the standard travel to fixed stop

function for machine kinematics with OEM transformation. With this function, tailstocks or sleeves, for example, can be traversed to

a fixed stop in order to clamp workpieces. The clamping torque and a fixed stop monitoring window can be programmed in the part

program and set in the machine data. The function regulates the force to an adjustable value in the approach direction. In this case,

it can be utilized simultaneously in several channels.

CCG compiler non-circular grinding (cam contour grinding)

Option; order code P10

Article No.: 6FC5800-0AP10-0YB0

Requirements: TRANSMIT option, order code M27 and polynomial interpolation option, order code M18.

This option is required for SINUMERIK 840D sl to allow the execution of part programs that have been generated with the CCG com-

piler tool. The OEM can either integrate the corresponding tool into the user interface on the PCU 50 or use it on an external PC.

The latest version of the tool is made available once on request, the option (runtime) must be ordered for each CNC. The CCG

compiler generates CNC programs in the polynomial format to allow the machining of non-circular contours on a cylindrical grinding

machine. The lift curves commonly used today, which describe the desired final contour in polar coordinates, are used as the input

data for programming and generating a complete CNC program.

The technology data, i.e. the number of infeed revolutions, allowance, sparking-out revolutions, angle of infeed and velocities, are

parameterized and taken into account when the part program is generated. The generated contour is not dependent on the tool

(grinding wheel) radius, because radius compensation (G41/G42) is active in the CNC.

Circle via center point and end point

Circular interpolation causes the tool to move along a circular path in a clockwise or counter-clockwise direction.

The required circle is described by:

• Starting point of circular path (actual position in the block before the circle)

• Direction of rotation of circle

• Circle end position (target defined in circular block)

• Circle center

The circle center can be programmed as an absolute value with reference to the current zero point or as an incremental value

with reference to the starting point of the circular path. If the opening angle is apparent from the drawing, then it can be directly

programmed. In many cases, the dimensions from a drawing are taken so that it is more convenient to program the radius in order

to define the circular path. In the case of a circular arc of more than 180 degrees, the radius specification is given a negative sign.

Circle via intermediate point and end point

If a circle is to be programmed, which does not lie in a paraxial plane but obliquely in space, an intermediate point can be used to

program it instead of the circle center. Three points are required to program the circle: the starting point, the intermediate point and

the end point.

Clamping monitoring

Clamping monitoring is one of the many extensive axis monitoring mechanisms implemented in SINUMERIK CNCs. When an axis is

to be clamped on completion of the positioning action, you can activate clamping monitoring using the PLC interface signal clamping

in progress. This may become necessary because it is possible for the axis to be pushed beyond the standstill tolerance from the

position setpoint during the clamping procedure.

The amount of deviation from the position setpoint is set via the machine data. During the clamping procedure, clamping monitoring

replaces standstill monitoring, and is effective for linear axes, rotary axes, and position-controlled spindles. Clamping monitoring is

not active in follow-up mode. When the monitoring function responds, its reactions are the same as those of the standstill monitoring.

 Position monitoring

Standstill monitoring

CNC high-level language

To meet the various technological demands of modern machine tools, a CNC high-level language has been implemented in

SINUMERIK CNCs that provides a high degree of programming freedom.

System variables

The system variables ($.) can be processed in the CNC program (read, partially write). System variables allow access to, for

example, machine data, setting data, tool management data, programmed values, and current values.

User variables

If a program is to be used flexibly, variables and parameters are used instead of constant values. SINUMERIK CNCs give you the

option of executing all CNC functions and addresses as variables. The names of the variables can be freely defined by the user.

Read and write access protection can also be assigned using attributes. This means that part programs can be written in a clear

and neutral fashion and then adapted to the machine as required, for example, free selection of axis and spindle address designa-

tions.

User variables are either global GUD or local LUD. LUD can also be redefined via machine data to make them into global program

user variables (PUD). They are displayed in the Parameters operating area under the user data softkey, where they can also be

changed. Global user variables GUD are CNC variables that are set up by the machine manufacturer. They apply in all programs.

Local user variables LUD are available to the user for parameterizing CNC programs. These data can be redefined in every CNC

program. These variables make programming more user-friendly and allow the users to integrate their own programming philosophy.

Indirect programming

Another option for the universal use of a program is indirect programming. Here, the addresses of axes, spindles, R parameters, etc.,

are not programmed directly, but are addressed via a variable in which their required address is then entered.

Program jumps

The inclusion of program jumps allows extremely flexible control of the machining process. Conditional and unconditional jumps are

available as well as program branches that depend on a current value. Labels that are written at the beginning of the block are used

as jump destinations. The jump destination can be before or after the exit jump block.

Program coordination in several channels

Program coordination makes it possible to control the time-related execution in parallel operation of several CNC channels using

plain text instructions in the part program. Programs can be loaded, started and stopped in several channels. Channels can be

synchronized.

Arithmetic and trigonometric functions

Extensive arithmetic functions can be implemented with user variables and arithmetic variables.

In addition to the 4 basic arithmetic operations, there are also:

• Sine, cosine, tangent

• Arc sine, arc cosine, arc tangent

• 2. Power of 2 (squaring), square root

• Absolute value

• Integer component, round to integer

• Exponential function, natural logarithm

• Offset, rotation, mirroring

• Scale modification

Comparison operations and logic combinations

Comparison operations with variables can be used to formulate jump conditions.

The comparison functions that can be used are:

• Equal to, not equal to

• Greater than, less than

• Greater than or equal to

• Less than or equal to

• Concatenation of strings

The following logic combinations are also available: AND, OR, NOT, EXOR (EXclusive OR). These logic operations can also be

performed bit by bit.

Macro techniques

Using macros, single instructions from a programming language can be grouped together to form a complex instruction. This

shortened instruction sequence is given a freely definable name and can be called in the CNC program.

The macro command is executed in the same way as the single instructions.

Control structures

The CNC normally processes the CNC blocks in the order in which they are programmed. Control structures allow the programmer

to define additional alternatives and program loops as well as program jumps.

The commands make structured programming possible, and make the programs much easier to read:

• Choice of 2 alternatives IF-ELSE - ENDIF

• Continuous loop control LOOP

• Counting loop FOR

• Program loop with start condition WHILE

• Program loop with end condition REPEAT

CNC operating modes

3 CNC operating modes can be selected in the Machine operating area:

• JOG

JOG CNC operating mode (jogging) is intended for the manual movement of axes and spindles, as well as for setting up the

machine. The set-up functions are reference point approach, repositioning, traveling with the handwheel or in the predefined

incremental mode, and redefinition of the CNC zero point (preset/set actual value).

• MDI

In MDI (Manual Data Input) CNC operating mode, it is possible to enter individual program blocks or sequences of blocks for

immediate execution via CNC Start. These blocks can then be saved in part programs. With the Teach In function, motion

sequences are transferred to a program by returning and storing positions. The Teach In function can be used in the MDI CNC

operating mode.

• AUTO

In AUTO (automatic) CNC operating mode, the part programs are executed fully automatically once they have been selected in

the workpiece, part program or subprogram directory (normal operation). During AUTO mode it is possible to generate and correct

another part program.

In the MDI and AUTO CNC operating modes, the sequence of a program can be modified using the following program control

functions:

• SKP Skip block (up to 8 skip levels)

• DRY Dry run feedrate

• ROV Rapid traverse override

• SBL1 Single block with stop after sets of machine functions

• SBL2 Single block with stop after every block

• SBL3 Stop in cycle

• M01 Programmed stop

• DRF Differential resolver function

• PRT Program test

Continue machining at the contour (retrace support), Run MyCC /RESU

Option; order code M24

Article No.: 6FC5800-0AM24-0YB0

When using 2D flat bed cutting procedures, e.g. laser, oxygen or water jet cutting, the machine operator can return to the program

continuation point (selected solely from the view of the workpiece) following an interruption in machining without exact knowledge of

the part program in order to continue machining the workpiece from that particular location.

The Continue machining at the contour function (retrace support) contains a ring buffer for the geometric information of the blocks

already executed. A new part program is generated from this for reverse travel.

Continue machining is used, for example, when the machine operator only notices the interruption in a 2D laser or water jet cutting

operation a few blocks after the actual interruption. The head has usually already progressed further in the machining process, and

must, therefore, be returned to continue machining.

Continuous dressing (parallel dressing)

With the continuous dressing function, the form of the grinding wheel can be dressed in parallel with the machining process. The

grinding wheel compensation resulting from dressing the wheel takes immediate effect as tool length compensation.

When the tool radius compensation is programmed to machine the contour and the tool radius changes because of the dressing of

the grinding wheel, the CNC computes the dressing amount online as a true tool radius compensation.

Continuous-path mode with programmable rounding clearance

The aim of the continuous-path mode is to avoid excessive deceleration at the block boundaries and to achieve as constant a tool

no undercuts are made on the workpiece.

If continuous-path mode G64 is selected, reduction in velocity takes place and contour corners are rounded at non-tangential

transitions. A soft contour transition without a jump in acceleration can be programmed with G641 ADIS=...

Contour handwheel

Option; order code M08

Article No.: 6FC5800-0AM08-0YB0

When the contour handwheel function is activated, the handwheel has a velocity-generating effect in AUTO and MDI CNC operating

modes on all programmed traversing movements of the path and synchronized axes.

A feedrate specified via the CNC program becomes ineffective and a programmed velocity profile is no longer valid. The feedrate,

in mm/min, results from the handwheel pulses as based on pulse weighting (machine data) and the active increment.

The handwheel's direction of rotation determines the direction of travel:

• Clockwise:

In the programmed direction of travel (even beyond block boundaries)

• Counter-clockwise:

Opposite to the programmed direction of travel (continuation beyond the start of the block is prevented).

 Feedrate interpolation (feed characteristic)

Contour monitoring

The following error is monitored within a definable tolerance band as a measure of contour accuracy. An impermissibly high following

error might be caused by a drive overload, for example. If an error occurs, the axes/spindles are stopped. Contour monitoring is

always enabled when a channel is active and in position-controlled mode. If the channel is interrupted or in the reset state, contour

monitoring is not active. Contour monitoring is also deactivated during execution of the travel to fixed stop function.

A cylindrical tunnel (tolerance field) with a definable diameter is placed around the programmed path.

Electronic counterweight

With weight-loaded axes without mechanical or hydraulic weight counterbalance, the vertical axis drops when the brake is released

and the servo enable is switched on. The undesired lowering dZ of the axis can be compensated by activating electronic weight

counterbalance. After releasing the brake, the constant weight counterbalance torque maintains the position of the vertical axis.

Sequence:

1. Brake holds Z axis

2. Brake is released; controller enable on; pulse enable on.

3. Z axis does not drop, but holds its position.

Electronic gear

The electronic gear function allows highly accurate kinematic coupling of axes with programmable gear ratio. Linking can be

specified and selected for any CNC axes via program or operator panel.

The electronic gear function makes it possible to control the movement of a following axis, depending on up to 5 leading axes.

The relations between the leading axis and the following axis are defined for each leading axis by a fixed gear ratio (numerator/

denominator) or as a linear or non-linear coupling using a curve table. The following axis can be a leading axis for another gear

system (cascading).

Real as well as simulated linear and rotary axes can be used as the leading and following axes. Master input values can be setpoints

generated by the interpolator (setpoint linkage) or actual values delivered by the measuring system (actual-value linkage). Using the

electronic gear with non-linear coupling, it is possible to create convex tooth faces during gear cutting and also to compensate the

non-linear properties of the process, for example.

Restricted functionality of export versions:

The number of simultaneously traversing axes is restricted to 4.

 Generic coupling

Electronic handwheels

Using electronic handwheels, it is possible to move selected axes simultaneously in manual mode. The handwheel clicks are

analyzed by the increment analyzer. If coordinate offset or coordinate rotation is selected, it is also possible to move the axes

manually in the transformed workpiece coordinate system.

The maximum input frequency of the handwheel inputs is 100 kHz. A third handwheel can also be operated as a contour handwheel.

The Contour handwheel function permits use of a handwheel on conventional turning machines (for ShopTurn applications, for

example) and also during grinding for traversing on a contour.

Once the Contour handwheel function has been activated, the handwheel has a velocity-generating effect in AUTO and MDI CNC

operating modes, i.e. a feedrate specified via the CNC program is no longer effective and a programmed velocity profile is no longer

valid. The feedrate, in mm/min, results from the handwheel pulses as based on pulse evaluation via machine data and the active

increment INC1, INC10,

The handwheel's direction of rotation determines the direction of travel: clockwise in the programmed direction, even over block

boundaries, and counter-clockwise up to the block start.

Files called series start-up files can be generated to enable transfer of a particular configuration, in its entirety, to other CNCs that

use the exact same software version, for example, CNCs that are to be used for the same machines.

Series start-up means bringing a series of CNCs to the same initial state as regards their data. You can archive/read selected CNC,

PLC and PCU data for series start-up. Compensation data can be optionally saved. The drive data are stored as binary data, and

cannot be modified.

Series start-ups can even be easily performed without a programming device: Simply create a startup file in the PCU, save it on a

PC card in the CNC, insert this card in the next CNC, and begin the series start-up procedure. Series start-ups can also be performed

via a network drive or a USB stick.

Evaluation of internal drive variables

Option; order code M41

Article No.: 6FC5800-0AM41-0YB0

The evaluation of internal drive variables can be used to control, i.e. by adaptive control, a second process variable (such as a path-

specific or axis-specific feedrate) depending on a measured process variable, e.g. spindle current. This permits, for example, the

cutting volume to be kept constant when grinding, or closing the grinding gap faster when scratching (first touch).

Evaluation of these drive variables also permits machines and tools to be protected from overload; this evaluation also facilitates

shorter machining times and an improved surface quality of the workpiece. Evaluation of internal drive variables is a requirement for

implementing adaptive control (AC). Adaptive control can be parameterized within the part program as follows:

• Additive influence:

The programmed value (F word) is corrected by adding.

• Multiplicative influence:

The F word is multiplied by a factor (override).

The following real-time variables can be evaluated as internal drive variables:

$AA_LOAD drive capacity utilization in %

$AA_POWER drive active power in W

$AA_TORQUE drive torque setpoint in Nm

$AA_CURR actual axis/spindle current in A

A safe position is assumed from the machining level without any collision between tool and workpiece. As well as the drive-autono-

mous stop and retract function, the CNC-controlled stop and retract function is also available. To permit gentle interpolated retraction

along the path or contour, the path interpolation can be processed further for a definable period following the trigger event.

The retraction axes are subsequently traversed in synchronism to an absolute or incremental position as programmed. These

functions are primarily used for gearing and grinding technologies.

Extended stop and retract ESR, drive-autonomous

Article No.: 6FC5800-0AM60-0YB0

The drive-autonomous extended stop and retract function can be used to separate the workpiece from the tool quickly and without

risk of damage in the event of a fault. This is distinguished from the control-based ESR function by the autonomous, purely axial stop

and retraction motion of the drive, which do not take into account any CNC coupling rules.

Feedforward control

Axial following errors can be reduced to almost zero with feedforward control. This feedforward control is therefore also called

following error compensation. Particularly during acceleration in contour curvatures, e.g. circles and corners, this following error

leads to undesirable, velocity-dependent contour violations.

• Velocity-dependent speed feedforward control

In velocity-dependent feedforward control, the following error can be reduced almost to zero at constant velocity.

• Acceleration-dependent torque feedforward control

You can use torque feedforward control to achieve precise contours even when the highest dynamic response is demanded. If the

settings are right, you can compensate the following error almost completely, even during acceleration. The result is excellent

machining precision even at high path velocities.

Feedrate interpolation (feed characteristic)

In accordance with DIN 66025, a constant feedrate over the part program block can be defined via address F. For a more flexible

definition of the feedrate profile, programming to DIN 66025 is expanded to include linear and cubic profiles over the path. The cubic

profiles can be programmed directly or as an interpolating spline.

This makes it possible, depending on the curvature of the workpiece to be machined, to program continually smooth velocity profiles,

which in turn allow jerk-free acceleration changes and thus the production of uniform workpiece surfaces.

You can program the following feedrate profiles:

• FNORM

Response according to DIN 66025 (default setting). An F value programmed in the CNC block is applied over the entire path of

the block, and is subsequently regarded as a fixed modal value.

• FLIN

An F value programmed in the block can be traversed linearly (rising or falling) over the path from the actual value at the beginning

of the block to the end of the block, and is subsequently regarded as a modal value.

• FCUB

The non-modally programmed F values (relative to the end of the block) are connected through a spline. The spline starts and

ends tangentially to the previous or following feedrate setting.

• FPO

The feedrate profile can also be programmed directly via a polynomial. The polynomial coefficients are specified analogous to

polynomial interpolation.

Feedrate override

The programmed velocity is overridden by the actual velocity setting via the machine control panel or by the PLC (0 % to 200 %).

In order for the cutting velocity along the contour to be kept constant, the feedrate calculation is referred to the operating point or

tool end point.

The feedrate can also be corrected by a programmable percentage factor (1 % to 200 %) in the machining program. This factor is

overlaid (multiplication) on the setting made at the machine control panel. The velocity setting from the PLC is axis-specific.

Follow-up mode

In follow-up mode, an axis/a spindle can be moved independently, while the actual value continues to be detected. The traversing

paths are updated in the display. Standstill, clamping and positioning monitoring functions are not effective in the follow-up mode.

Once follow-up mode is cancelled, reference-point approach of the axis does not have to be repeated.

Frame concept

Frame is the common term for a geometric expression describing an arithmetic operation, for example, translation or rotation.

For SINUMERIK CNCs, the frame in the CNC program transfers from one Cartesian coordinate system to another, and represents the

spatial description of the workpiece coordinate system.

The following are possible:

• Basic frames: Coordinate transformation from basic coordinate system BCS into basic zero system BZS

• Settable frames: Work offsets using G54 to G57/G505 to G599

• Programmable frames: Definition of workpiece coordinate system WCS

The frame concept makes it possible to transform Cartesian coordinate systems very simply by offsetting, rotating, scaling and

mirroring.

The following instructions are used to program these options:

• TRANS programmable work offset

• ROT rotation in space or in a plane

• ROTS rotation referred to the solid angle projected into the planes

• SCALE scaling (scale factor)

• MIRROR mirroring

• TOFRAME frame according to tool orientation

• TOROT rotary component of programmed frame

• PAROT frame for workpiece rotation (table rotation)

• MEAFRAME frame calculation from 3 measuring points in space (for measuring cycles).

The instructions can also be used several times within one program. Existing offsets can either be overwritten or new ones can be

added.

Additive frame instructions:

• ATRANS additive programmable work offset

• AROT additive rotation in space or in a plane

• ASCALE scale factor (multiplication)

• AMIRROR repeated mirroring

• AROTS additive rotation referred to the solid angle projected into the planes

the energy stored during spindle rotation or axis movement is fed back into the DC link, following the same principle as that used by

generators.

Generic coupling

We offer 5 different performance levels for generic (general) coupling (CP) of axes/spindles. The functionality is scalable via the

number of leading axes to one following axis, via coupling characteristics ranging from simple functionality through to technological

innovations and via the simultaneously activatable coupling types.

The options CP-Static, CP-Basic, CP-Comfort and CP-Expert are available. These options can be combined as required. The number

of coupled objects actively in use at the same time is monitored, i.e. if multi-edge machining and synchronous spindle are not

simultaneously in use, for example, CP-Basic is sufficient. However, if these two functions need to be used simultaneously, CP-Static

will be required additionally (or, depending on the number of additional coupling functions, CP-Comfort).

High-speed CNC inputs/outputs can be used for machines, such as those used for grinding and laser machining, as well as in

SINUMERIK Safety Integrated.

Input signals are possible for the following:

• Several feedrate values in one block (caliper function)

The function allows modification of the feedrate through external signals. 6 digital inputs can be combined with 6 different feedrate

values in a CNC block. There is no feed interruption in this case. An additional input can be used to terminate the infeed (starting

a dwell time), and another input can be used to start immediate retraction. Depending on the input, the retraction of the infeed axis

(or axes) is initiated by a previously specified absolute value in the IPO cycle. The remaining distance-to-go is deleted.

• Several auxiliary functions in one block

Several auxiliary functions can be programmed in one CNC block. These functions are transferred to the PLC depending on a

comparison operation or an external signal.

• Axis-specific delete distance-to-go

The high-speed inputs cause conditional stopping and delete distance-to-go for the path or positioning axes.

• Program branches

The high-speed inputs make program branches within a user program possible.

Interrupt routines with fast retraction from the contour

Option; order code M42

Article No.: 6FC5800-0AM42-0YB0

Interrupt routines are special subprograms which can be started on the basis of events (external signal) in the machining process.

Any part program block currently in progress is interrupted. The positions of the axes at the time of interruption are saved automati-

cally. It is also possible to save such things as the current states of G functions and the current offsets (SAVE mechanism) in buffer

storage, making it possible to resume the program at the point of interruption later without difficulty.

Four additional program levels are available for interrupt routines, that is, an interrupt routine can be started in the 8th program level

and lead as high as the 12th program level. An interrupt such as the switching of a high-speed CNC input can trigger a movement

via the special subprogram, which allows fast retraction of the tool from the workpiece contour currently being machined.

The retraction angle and the distance retracted can also be parameterized. An interrupt routine can also be executed following the

fast retraction.

Inverse-time feedrate

For CNC's, it is possible to program the time required to traverse the path of a block (rpm) instead of programming the feedrate for

the axis movement with G93. If the path lengths differ greatly from block to block, a new F value should be determined in every block

when using G93.

When machining with rotary axes, the feedrate can also be specified in degrees/revolution.

Involute interpolation

Option; order code M21

Article No.: 6FC5800-0AM21-0YB0

Using involute interpolation, it is possible to program a spiral contour with the shape of a circular involute in one CNC block instead

achieved, together with a shorter machining time. Undesirable facets, which could result from coarse polygon functions, are thus

avoided.

Furthermore, it is unnecessary to define the end point for the involute interpolation exactly on the involute defined by the start point;

it is possible to enter a maximum permissible deviation using machine data.

Laser switching signal, high-speed, Run MyCC /HSLC

Option; order code M38

Article No.: 6FC5800-0AM38-0YB0

For high-speed laser machining, e.g. of aperture plates, the laser is switched on and off automatically and with a very high positional

accuracy relating to the path. Under the prerequisite that all movements for which the laser must be switched off are made in rapid

traverse mode G0, it is possible to logically combine the switching signal for the laser with the rising or falling edge of G0. The laser

switching signal can also be coupled to an adjustable G1 feedrate threshold value, if required. To achieve the fastest possible

responses, the switching on and off of the digital laser signal is controlled by a hardware timer with microsecond precision depending

on the actual axis position. No programming measures are required for switching the laser itself on and off, as these procedures are

directly linked to the programmed G functions. It is only necessary to program a release with CC_FASTON (DIFF1, DIFF2) for the

path section in which the laser is switched on or off. Together with this release, the two offset values, which can offset the switching

on and off of the laser by a specific path differential in relation to the position setpoint are entered.

Leadscrew error compensation / measuring system error compensation

On SINUMERIK CNCs, interpolating compensation is divided into two categories:

• Leadscrew error compensation (LEC) or measuring system error compensation (MSEC) as axial compensation (basic axis and

compensating axis are always identical) and

• Sag error and angularity error compensation as cross-axis compensation (basic axis affects other compensation axis).

The principle of "indirect measuring" on CNC-controlled machines is based on the assumption that the leadscrew pitch is constant

at every point within the traversing range, so that the actual position of the axis can be derived from the position of the drive spindle

(ideal situation).

Tolerances in ball screw production, however, result in large dimensional deviations to a lesser or greater extent (referred to as

leadscrew error). These are complemented by dimensional deviations caused by the measuring system as well as its installation

tolerances on the machine (measuring system errors), plus any machine-dependent error sources. Because these dimensional

deviations directly affect the accuracy of workpiece machining, they must be compensated for by the relevant position-dependent

compensation values.

The compensation values are derived from measured error curves and entered in the CNC in the form of compensation tables during

commissioning. The relevant axis is compensated using linear interpolation between the intermediate points.

Leadscrew error compensation, bidirectional

Option; order code M54

Article No.: 6FC5800-0AM54-0YB0

Bidirectional compensation is an expansion of the leadscrew error compensation function (LEC) or the measuring system error

compensation function (MSEC). By contrast with the LEC and MSEC, bidirectional compensation acts in both directions.

Restricted functionality of export versions:

The correctable tolerance band is restricted to 1 mm (0.039 in).

Limit-switch monitoring

Preceding the emergency stop switch, hardware limit switches, which take the form of digital inputs controlled via the PLC interface,

limit the traversing range of the machine axes. Deceleration is realized either as rapid deceleration with setpoint zero or along a

braking characteristic. The axes must be retracted in the opposite direction in the JOG CNC operating mode.

Software limit switches precede the hardware limit switches, are not passed, and are not active until reference point approach has

been completed. Following preset, software limit switches are no longer effective. A second pair of plus/minus software limit switches

machines is to be prevented, it can be permanently linked to a particular CNC hardware unit by means of an addition to the program.

Lock MyPLC

The PLC machine program can be comprehensively protected by the know-how protection functionality provided by SIMATIC STEP 7

software version 5.5 SP3. This software guards technological knowledge against unauthorized access and modification. It prevents

the reverse engineering of machines, thus safeguarding the investments you have made.

Look Ahead

During the machining of complex contours, most of the resulting program blocks have very short paths with sharp transitions. If a

contour of this type is processed with a fixed programmed path velocity, an optimum result cannot be obtained. In short traversing

blocks with tangential block transitions, the drives cannot attain the required final velocity because of the short path distances.

Contours are rounded when traveling around corners.

The Look Ahead function is a means of optimizing the machining speed by looking ahead over a parameterizable number of travers-

ing blocks. For tangential block transitions, the axis is accelerated and decelerated beyond block boundaries, so that no drops in

velocity occur. For sharp path transitions, rounding of the contour is reduced to a programmable path dimension.

Look-ahead detection of contour violations

With collision detection CDON on and active tool radius compensation, the CNC monitors tool paths through look-ahead contour

calculation. Potential collisions are promptly identified in this way and actively prevented by the CNC.

For example, for an excessively large tool radius, the CNC identifies critical machine situations, which it compensates for by

modifying the tool paths.

• Bottleneck detection

Because the tool radius is too large to produce a narrow inside contour, the bottleneck is bypassed and an alarm output.

• Contour path shorter than tool radius

The tool bypasses the workpiece corner along a transition circle, then continues precisely on the programmed path.

• Tool radius too large for inside machining

In such cases, the contours are machined only as much as is possible without causing a contour violation.

With the machining package 5 axes, 5-axis machining tasks, such as the milling of free-form surfaces, can be simply implemented.

To this end, the machining package 5 axes provides the following functions:

• 5-axis transformation with tool orientation TRAORI

In 5-axis machining, geometric axes X/Y/Z are supplemented by additional axes such as rotary axes for swiveling the tool. The

machining task can be completely defined in Cartesian spatial coordinates with Cartesian position and orientation. The path vector

is converted in the control into the machine axes, including position and orientation, via 5-axis transformation.

• 5-axis tool length compensation for 5-axis machining

When machining with the 4th/5th axis, the lengths of the selected tool are automatically included and compensated in the axis

movement.

• Oriented tool retraction

If machining is interrupted because of tool breakage, for example, a program command can be used to carry out defined, oriented

tool retraction.

• Tool-oriented RTCP

With the remote tool center point RTCP function, the tool swivel axes can be positioned in the manual mode, as long as there is

compliance with the tool center point marked by the tool tip. The RTCP function simplifies the inclusion of program interpolation

points in manual mode with orientation of the tool.

• Cardan milling head/nutating head

Requirements: Machining package 5 axes with 5-axis transformation.

Using a cardan milling head in conjunction with the Nutating head function, it is possible to machine outside contours of spatially

formed parts at high feedrates. To do this, the CNC performs a 5-axis transformation. 3 translatory main axes X/Y/Z determine the

tool operating point; 2 rotary axes, one of which is an inclined axis (angle can be set in the machine data), permit virtually any

orientation in the working area. Version 1 and version 2 of the cardan milling heads are supported. In the case of version 2, the

position of the operating point does not change when the tool is swiveled; the compensating movements required for orientation

changes are minimal. Includes multi-axis interpolation (> 4 interpolating axes). The machining package 5 axes does not include

any additional axes/spindles which might be required.

A main program can also be called from within another main program or subprogram.

Master/slave for drives

Option; order code M03

Article No.: 6FC5800-0AM03-0YB0

The master/slave for drives function is required when 2 electrical drives are mechanically linked to an axis. With this link, a torque

controller ensures that both drives produce the exact same amount of torque, so that the motors do not work in opposition. In order

to attain tensioning between the master and slave drives, a tension torque specifiable via machine data can be applied to the torque

controller.

Application examples:

• Increasing the power rating and (occasional) mechanical linking of drives

• Drive with 2 motors that operate on a gear rack

• Remachining of wheel sets for rail vehicles

• Zero backlash reversing of mutually tensioned drives

An axis can also be a leading axis for multiple links.

Master-value coupling and curve table interpolation

For special technologies (presses, transfer lines, printing machines, etc.), the replacement of mechanical, cyclic transport tasks with

electronic functionality in AUTOMATIC mode requires constant coupling and decoupling functions between leading and following

axes. To this end, the synchronous spindle function has been expanded to include the master value coupling function, which makes

it possible for linear guide and following axes to be coupled via curve tables in the CNC program.

Any function relations between axis positions can be approximated. Soft coupling avoids the sudden change in velocity that occurs

when the guide axis is activated. Offsets (e.g. 12°), scalings (e.g. 1.00023) and mirroring using frame instructions are possible.

Electronic curve table interpolation replaces the cam disks that were once required for the computerized numerical control of cyclic

machines. Complex sequences of motion can be easily defined using familiar CNC language elements. The external reference

variable (e.g. "line shaft") is formed by the CNC's master value. The functional relation between leading and following axis can be

subdivided into segments of the leading axis (curve segments). In these curve segments, the link between master value and

following value is described using mathematical functions (normally through 3rd degree polynomials).

Cyclic machines are distinguished by constantly repeated cyclic operations with high throughput and high productivity in machining,

transport, packaging and parts handling (for example, packaging machines, presses, woodworking machines, printing machines).

With the SINUMERIK CNC, technological functions such as synchronism, electronic transfer and positioning for cyclic machines can

be implemented. Mechanical systems (line shaft, gearing, cam disks, couplings and cams) are replaced by an electronic solution

(master value coupling, curve tables, synchronized actions, and electronic cams).

In addition, the electronic functionality permits fast, axis-specific optimization, high-speed phase and path compensation, fast re-

sponses to faulty or missing parts, and fast synchronization and resynchronization, as well as decoupling from the leading axis and

execution of autonomous movements. Axis cycles and synchronization calculations are carried out in the IPO cycle.

Measuring from synchronized actions, for example, is used for detecting edges on continuous workpieces and for measuring print

marks (on continuous film, for example).

The Measure kinematics function supports the calibration of kinematic structures of 5-axis machines.

The SINUMERIK 840D sl is able to determine the parameters of kinematic transformations of the digitally or manually alignable rotary

axes quickly and automatically.

The function is ideal for initial startup, because a dimension drawing of the machine is not required. The function can also be used

Measuring cycles

Option; order code P28

Article No.: 6FC5800-0AP28-0YB0

In the case of tool measuring, the loaded tool (typically in the revolver on turning machines) is moved towards the probe, which is

either in a fixed position or swiveled into the working range by a mechanical device.

The automatically derived tool geometry is entered in the relevant tool offset data record.

In the case of workpiece measuring, a probe is moved towards the clamped workpiece like a tool. The flexible structure of the

measuring cycles means that it is possible to handle virtually every measuring task associated with turning or milling.

The flying measurement principle is used in SINUMERIK CNCs. The advantage of this principle is that the probe signal is processed

directly in the CNC. The measuring parameters and the results of the measurements are output extremely clearly in separate

displays, which are either automatically deselected at the end of the cycle or can be acknowledged when starting the CNC.

The result of the workpiece measurement can either include automatic offset of the zero point or a correction of the tool wear by the

difference between the actual value and the setpoint. The measurement results can be logged in a file.

Siemens measuring cycles offer a standard log, which can be freely configured by the user.

In order to measure tool and workpiece dimensions, a touch-trigger probe is required that supplies a constant signal (rather than a

pulse) when deflected. The probe should switch without any bounce, and mechanical adjustment may be necessary. Multidirectional

probes can be used for all tool and workpiece measurements on turning and milling machines. Bidirectional probes are treated like

a mono probe for workpiece measurements on milling and machining centers, but are not suitable for tool measurements.

Monodirectional probes can be used on milling machines and machining centers with slight restrictions in workpiece measurements,

but are not suitable for tool measurements or for workpiece measurements on turning machines.

Measuring functions/measuring cycles

Measuring functions can execute either channel-specifically including all axes programmed in the measuring block as well as axially

from the part program or from synchronized actions beyond CNC block limits. Measuring cycles are subprograms for implementing

specific measuring tasks on tools or workpieces.

They are easy to use and simply require the input of values in predefined parameters.

• Measuring in JOG

• 2 probes can be connected simultaneously

• Measurement in space with frame

• Adaptable measuring modes with/without deletion of distance-to-go

• Display and logging of measuring parameters and results (with measuring cycles)

• Results can be read in the machine or workpiece coordinate system

• Cyclic measurement with synchronized actions parallel to workpiece machining

With the advantages of the measuring functions and measuring cycles, the machining accuracy is assured, unproductive time is

reduced, sources of error are eliminated and further production processes are automated.

Measuring stage 1

Up to 2 switching probes can be connected simultaneously to the CNC. In the case of channel-specific measuring, the measuring

process for a CNC channel is always activated from the part program running in the relevant channel. All of the axes programmed

in the measuring block take part in the measuring process.

It is possible to program a trigger event (rising or falling edge) and a measuring mode with or without deletion of distance-to-go for

each measuring process. The results of measurements can be read in the part program or with synchronized actions in both the

machine and the workpiece coordinate system. You can test the deflection of the probe by scanning a variable and outputting it to

the PLC interface and deriving responses in the part program.

Measuring stage 2 (option, order code M32) provides expanded functionality (for example for axial measuring, evaluation of up to

4 trigger events, and cyclic measuring).

block. In the case of simultaneous measuring, up to 4 trigger events can be evaluated per position control cycle. Measured values

are read as a function of the 3 parameters: probe, axis and measuring edge.

In the case of continuous (cyclic) measuring, the measurement results are written to a FIFO variable. Endless measuring can be

achieved by reading out the FIFO values cyclically. Measurement results can be logged in the form of a file. The measuring cycles

Metric/inch dimensions

Depending on the measuring system used in the production drawing, it is possible to program workpiece-related geometrical data

in either metric units (G71) or inches (G70). The CNC is set to a basic system regardless of the dimension system that has been

programmed.

You can enter the following geometrical data directly and let the CNC convert them into the other dimension system (examples):

• Position data X, Y, Z, etc.

• Interpolation parameters I, J, K and circle radius CR

• Pitch

• Programmable work offset (TRANS)

• Polar radius RP

With the G700/G710 programming expansion, all feedrates are also interpreted in the programmed measuring system (inch/min or

mm/min). In the Machine operating area, the operator can switch back and forth between inch and metric dimensions using a softkey.
