Description

SPINDLE IS CLAMPED

An attempt was made to program a block containing a spindle code other than an M05 while the

PAL servo clamp request flag for the spindle was set.

SPINDLE MODES INCOMPATIBLE

An attempt was made to enter virtual mode when the spindle that is used for this mode is

synchronized as the follower spindle or an attempt was made to perform end face milling during

synchronization.

SPINDLE MOTOR SPEED TOO HIGH

When using a 1326 motor as a spindle, feedback resolution combined with your configured

maximum spindle speed would return feedback counts faster than the control can reliably

decode. Either reduce the maximum configured spindle speed, or reduce the configured

feedback counts for the spindle in AMP.

SPINDLE MUST BE THE LAST SERVO

When the system is AMPed, the spindle must be assigned to the first available port after all axes

have been assigned.

SPINDLE NOT ASSIGNED

A spindle axis was AMPed, but not assigned to any process.

SPINDLE ORDER ERROR, AMP AUX. 2 SECOND

AMP order of spindles must be primary spindle, aux. spindle 2, aux. spindle 3.

SPINDLE ORDER ERROR, AMP AUX. 3 THIRD

AMP order of spindles must be primary spindle, aux. spindle 2, aux. spindle 3.

SPINDLE ORDER ERROR, AMP PRIMARY 1ST

AMP order of spindles must be primary spindle, aux. spindle 2, aux. spindle 3.

SPINDLE SYNC NOT CONFIGURED

The programmer attempted to enter synchronized spindle mode before it was configured in

AMP.

SPINDLE SYNC UNAVAILABLE THIS PROCESS

An attempt was made to enter synchronized spindle mode on a dual--process control when the

process was not yet configured for both spindles in the synchronized pair.

SQUARE ROOT OF NEGATIVE ERROR

Internal math error has occurred; contact Allen-Bradley customer support services.

SQUARE ROOT OF NEGATIVE INVALID

An attempt was made to determine the square root of a negative number using the calculator or

through a paramacro SQRT command.

STORED PASSWORD LIST TO BACKUP

This message appears after the password list has been successfully stored to the control’s

backup memory.

STORING TO BACKUP - PLEASE WAIT

This message appears whenever AMP or axis calibration data in RAM is being stored in backup

memory.

SYMBOL NAME FORMAT ERROR

Check the remote symbol and CNC symbol to make sure they exist on both remote and CNC.

Check the table of the read only or write only variables.

SYMBOL NOT FOUND

Check the remote symbol and CNC symbol to make sure they exist on both remote and CNC.

Check the table of the read only or write only variables.

SYNCHRONIZATION DEADLOCK

A synchronization code is activated and caused the activating process to wait on a process that

is already waiting.

SYNCH SPINDLES MISCONFIGURED

Causes for this could be: only one spindle (either controlling or follower) was defined in the

synchronized spindle pair, you exceeded the simple feedback ratio limitation of 10 (e.g., 11:1 or

2:13), or on a multiprocess system, one (or both) of the spindles in the synch pair is currently not

available to the process making the synchronization request.

SYNCH SPINDLES REQUIRE FEEDBACK

One or both of the spindles, configured in AMP as a member of a synchronized pair, did not

have feedback. Both spindles in a synchronized pair must be equipped with an AMP configured

feedback device.

SYNTAX ERROR (COMMA)

A missing comma or an extra comma was found in the program block.

SYSTEM DIAGNOSTIC #1

An illegal parameter was passed into a switch statement (mid-program start) in the control

software. Contact Allen-Bradley customer support services.

SYSTEM DIAGNOSTIC #2

An illegal parameter was passed into a switch statement (ASCII buffer task) in the control

software. Contact Allen-Bradley customer support services.

SYSTEM DIAGNOSTIC #3

An illegal parameter was passed into a switch statement (ASCII buffer task) in the control

software. Contact Allen-Bradley customer support services.

Appendix B

Error and System Messages

Message

Description

SYSTEM MODULE GROUND FAULT

The 1394 system module has detected a ground fault. The system generates a ground fault

when there is an imbalance in the DC bus of greater than 5A. This drive error can be caused by

incorrect wiring (verify motor and ground wiring), motor malfunction, or an axis module IGBT

malfunction.

SYSTEM MODULE OVER TEMP

The 1394 contains a thermal sensor which senses the internal ambient temperature. Causes

could be: that the cabinet ambient temperature is above rating. The machine duty cycle

requires an RMS current exceeding the continuous rating of the controller. The airflow access to

the 1394 is limited or blocked. This does not necessarily indicate a motor over temperature.

Motor over temperture sensors should be wired directly into the E-Stop string.

SYSTEM MODULE OVER VOLTAGE

The 1394 system module buss voltage exceeds the maximum operating voltage. The dc power

bus is continuously monitored. If it exceeds a preset level (810V dc), a fault is sensed and the

power supply is disabled. There are several possible causes for this error.

·an undersized shunt requirement

·a blown shunt regulator fuse

·a malfunctioning shunt regulator transistor

· the power driver board is malfunctioning and incorrectly sensing the bus voltage

· an incorrectly set CNC acc/dec rate

· an excessive input line voltage

· the system inertia is too high causing excessive energy to be returned to the power supply bus

·a vertical axis with insufficient counterbalancing is overdriving the servomotor and causing excessive

energy to be returned to the power supply bus

· an incorrect power supply is installed in your system. Make sure you are using a CNC power supply

SYSTEM MODULE PHASE LOSS

The 1394 system module has detected a loss of one of the input power phases. The

three--phase input line is monitored and a fault will be issued when a phase loss is detected.

Typical causes include, one or more input line fuses have opened, contactor malfunction, or

incorrect wiring.

SYSTEM MODULE UNDER VOLTAGE

The 1394 system module voltage does not meet the minimum operating voltage. The DC power

buss shall activate the under voltage limit when the bus drops to 275 VDC or less. It will clear at

300 Vdc. Typical causes include low voltage on the three phase input.

(T) WORD IN CIRCULAR MODE

An attempt was made to activate a tool length offset in a block that generates a circular move.

Tool length offsets can be activated only in linear blocks (or in non-motion blocks if AMP is so

configured).

T--WORD NOT ALLOWED WITH M06

NEXT TOOL IN T WORD was selected as the tool--change type in AMP while a T--word is

programmed in an M06 block.

TAN CIRCLE NOT IN 1ST BLOCK

When editing a program, an attempt was made to digitize an arc using {CIRCLE TANGNT} as

the first block in the program. To use this digitizing format, the control must first have a tool path

programmed to make the arc tangent.

TEMPLATE PROGRAM NOT FOUND

A transfer line quick view item was selected without the correct part program template present in

the protected directory. There are 19 transfer line cycles and there must be part program

templates QV01 thru QV19 present in the protected directory. Refer to your T-LINE-9 Quick

Start guide for details on replacing/restoring these part program templates.

THIRD SPINDLE NOT AVAILABLE

AMP configuration error; spindle 3 can be configured only on a 9/290.

THIRD SPINDLE NOT CONFIGURED

For spindle 3 to be programmable, it must be configured in AMP; a decode error.

THRDS/IN WORD FORMAT FINER THAN

The word format programmed is requesting a finer resolution than the axis word format for the

corresponding axis allows. These word formats are set in AMP.

THREAD FEEDRATE TOO LARGE

The lead is too large in threading mode. Program slower spindle speed.

THREAD LEAD ERROR

The thread lead was too large or too small. This commonly occurs when cutting a variable

thread lead and before the end of the threading pass is reached. Either the lead goes to zero

for a decreasing lead thread, or an axis speed would exceed its maximum allowable cutting

feedrate when cutting an increasing lead thread.

B-42

Appendix B

Error and System Messages

Message

Description

THREAD LEAD IS ZERO

No thread lead has been programmed in a block that calls for thread cutting. Thread lead is

programmed with either an F- or an E-word.

THREAD PULLOUT DISTANCE TOO LARGE

The programmed threading pullout distance is larger than the programmed distance of the

thread departure.

THREAD PULLOUT STOPPED AT I--PLANE

The chamfer block of a threading cycle is shortened so that the combination of pullout angle and

pullout distance does not cause the retract in axis 1 to go beyond the I--plane. The AMP pullout

angle is still used for the chamfer.

THREADING DISTANCE IS ZERO

A threading cycle has been programmed with no thread. Program an end-point or an end-point

different from the start-point.

TIME-OUT OCCURRED WHILE WAITING FOR INPUT

When downloading AMP or PAL from the ODS workstation to the control, the message OKAY

TO DOWNLOAD? (Y/N): appears on the control screen. If you do not respond within an allowed

time, this error will appear.

TIMER MUST START WITH #

You have used incorrect search string syntax in the PAL search monitor utility.

TOO MANY ( [ ) IN EXPRESSION

The control has found an unmatched number of [] in a program block or calculator operation. All

left brackets “[”must have a corresponding right bracket “]”.

TOO MANY ( ] ) IN EXPRESSION

The control has found an unmatched number of [] in a program block or calculator operation. All

right brackets “]”must have a corresponding left bracket “[”.

TOO MANY 7300 PATTERNS IN MEMORY

An attempt was made to enter a 7300 pattern into the control’s memory when the internal

cross-reference table of pattern repeat names was full. The internal cross-reference table of

pattern repeat names can only hold 20 pattern repeat names.

TOO MANY ACTIVE PROCESSES CONFIGURED

An AMP has been loaded that has too many actively configured processes for this controller

model. The 260 series and the dual lathe can have only 2 active processes.

TOO MANY AXES AMPED FOR HARDWARE

An AMP has been loaded that has too many configured axes for this controller model. The

9/440 series can have only up to 6 axes.

TOO MANY AXES PROGRAMMED

Too many axis letters were programmed in a fixed cycle block.

TOO MANY AXES SELECTED FOR DISPLAY

When using the {AXIS SELECT} softkey, you can display only 6 axes. If you attempt to display

more than 6 axes, this message is displayed.

TOO MANY CODES IN SYNCH BLOCK

Synch codes must be in a block by themselves, except for an N- or O-word. (9/260-9/290 dual

lathe only)

TOO MANY DECIMAL POINTS

A word or parameter value has been programmed with two or more decimal points.

TOO MANY DEVICES ON I/O RING

The I/O ring cannot support the number of devices that has been connected.

TOO MANY EXPRESSION NESTS

The maximum number of nested expressions is 25; for example, [P3+[P4+[P5]]] has 3

expressions nests.

TOO MANY G67’S

A G67 cancel modal paramacro code was executed when no modal paramacro was active.

This is typically caused when there are fewer nested modal paramacros than the programmer

expected.

TOO MANY I-J-K SETS

An attempt was made to define a local paramacro parameter that is greater than #33 using I,J,K,

argument sets. A maximum of 10 different I, J, K, sets may be programmed for each set of local

parameters.

TOO MANY MACRO CALLS

The maximum number of nested paramacros was reached. Only 4 paramacros can be active at

any one time.

TOO MANY MOTORS AMPED ON 1ST BOARD

The AMP parameter for the number of motors on the first servo board is larger than the number

of axes in the system.

TOO MANY NESTED (DO) COMMANDS

More than the allowable number paramacro DO loops are active at one time. A maximum of 3

nested DO loops are allowed.

TOO MANY NONMOTION BLOCKS-DEADLOCK

There were too many non-motion blocks encountered during the look-ahead for cutter

compensation or QPP. Consult Allen-Bradley customer support services.

B-43

Appendix B

Error and System Messages

Message

Description

TOO MANY NONMOTION CHAMFER/RADIUS BLOCKS

Too many non-motion blocks separate the first tool path that determines the chamfer or radius

size (programmed with a ,R or ,C) from the second tool path. A maximum number of

non-motion blocks is set in AMP by the system installer. A non-motion block is defined as any

block that does not generate axis motion in the current plane.

TOO MANY POCKETS IN ROUGHING CYCLE

A maximum of 2 pockets can exist in a roughing cycle.

TOO MANY QPP NONMOTION BLOCKS

Too many non-motion blocks separate the first and second tool paths with unknown

intersections in QuickPath Plus. A maximum number of non-motion blocks is set in AMP by the

system installer. A non-motion block is defined as any block that does not generate axis motion

in the current plane.

TOO MANY SHARED SPINDLES

Too many spindles were specified as being shared by two or more processes.

TOO MANY SPINDLES

More than one spindle is configured on the control.

TOO MANY SUBPROGRAM CALLS

The maximum number of nested sub-programs was reached. Only 4 sub-programs may be

active at any one time.

TOOL CONFIGURATION WILL NOT FIT

When assigning a custom tool in the random tool table, the number of pockets assigned to the

tool relative to the position of the selected shaft pocket will conflict with a different tool already

assigned to a pocket. If the custom tool is to be assigned as entered, it must be assigned to a

different shaft pocket, or the tool that conflicts with the custom tools location must be moved.

TOOL ENTRY EXCEEDS LIMIT

The selected tool number entered is greater than the AMP’ed maximum tool number entered by

the system installer.

TOOL GROUP DOES NOT EXIST

An attempt was made to edit a tool group in the tool life management tables that does not yet

exist in the tool directory. A group must be created by using the {TOOL DIR} softkey options.

TOOL OFFSET CHANGES NOT ALLOWED

During certain cycles, G10 tool change operations are not allowed.

TOOL OFFSET REQUIRES MOTION BLOCK

A tool offset cannot be changed in a non-motion block. A non-motion block is any block that

does not generate axis motion in the current plane.

TOOL RADIUS TOO LARGE

The programmed tool radius in a G88 or G89 pocket cycle is too large for the pocket contour. A

smaller radius tool must be used to machine out the current pocket contour.

TOOL RADIUS TOO SMALL FOR POCKET SIZE

The programmed tool radius in a G88 or G89 pocket cycle is too small for the pocket contour.

Either select a larger tool for the pocket contour or reduce the amount of material to be removed

each rough cut of the cycle.

TOP OF PROGRAM REACHED

When performing one of the program search operations, the first block in the program has been

reached.

TRAVERSE NOT ALLOWED ON :

An attempt was made to move an axis at rapid traverse before it was been homed. This only

applies to axes that have software overtravel limits.

TYPE 1 INTERRUPT INCOMPATIBLE WITH G24

This message occurs when returning from a type 1 program interrupt that previously interrupted

a G24 block. The interrupt is allowed however the return move is invalid since the axis was

previously in the G24 mode. You must manually intervene to continue program execution. We

recommend switching to a type 2 program interrupt.

UART PORT IS ALREADY OPEN

The requested serial communications port has already been opened. This message will appear

if an attempt is made to send data to a port that is currently being used.

UNABLE TO OPEN PROGRAM

The control cannot find the program that is requested. Make sure the program name is entered

correctly or the peripheral device has the correct programs loaded in it.

UNABLE TO OPEN THE UART PORT

A serial communication port error has occurred; retry. The conditions that can lead to this error

are unusual and generally will not exist when a second attempt is made to open the port. If this

error is generated continuously, it indicates that there may be a communications port hardware

failure.

B-44

G-code Tables

Appendix Overview

This appendix lists the G-codes for 9/Series turning center. This table is

presented numerically by G--code system B along with a brief description

of their use. These G-codes are discussed in detail in the sections within

this manual that refer to their specific use.

The group numbers given in the table refer to modality. Group 00 is not

modal and independent of other G-codes. The remaining G-code groups

are modal with other G-codes with the same group number. This means

programming a G-code in group 1 replaces any other active group 1

G-code, but does not affect any G-codes that are not in group 1.

Important: This manual assumes that G--code system C is used.

Allen-Bradley 7300 Series CNC Tape

Compatibility

Appendix Overview

The 7300 Series CNC tape compatibility feature has been developed for

customers with an existing library of standard 7320 and 7360 CNC tapes.

This feature allows those 7300 tapes to be read and executed by the

control. If desired, these 7300 tapes can be copied into the control’s

memory to allow editing and execution, or they can be executed directly

from tape, with the exception of 7300 pattern repeat subprograms.

Important: This feature is not intended to let you to develop new 7300

part programs with the control. We strongly recommend that for new part

programs, you learn to develop them by using the control’s programming

method.

Important: S--Curve Acc/Dec mode is not available in 7300 mode.

To use the 7300 tape compatibility feature, the system installer must enable

this feature in PAL. Refer to your system installer’s documentation and the

PAL manual for details on how the 7300 Series CNC tape format feature is

activated.

G-code Compatibility

Table D.A lists all of the 7300 G-codes that the control can execute in 7300

mode. See the System 7360 Programming Manual for details on these

G28 and G29 Automatic Thread Cutting or Roughing Cycle

G28 and G29 are not standard 7300s Lathe G-codes, but have been

provided to enable automatic thread cutting or roughing. Both G28 and

G29 are used for the Automatic Thread Cutting cycle. This Automatic

Thread Cutting feature simplifies part programming of multiple-pass

thread cutting operations for straight or tapered constant-lead threads.

With this feature, an entire multi-pass thread cutting operation is

programmed in only two data blocks. These blocks contain parameters

that specify the following characteristics of the thread:

final thread depth

thread depth of first pass

infeed path

infeed feedrate

thread length

thread lead

pullout-in-lead distance

return pass clearance

return pass feedrate

Important: G28 and G29 are programmed consecutively within the part

program. The first automatic threading block must contain a G28 code; the

next block must contain a G29 code. An error occurs if you program these

G-codes separately.

When a G33 code is programmed in a G29 data block, it establishes

Thread Cutting mode for the automatic multi-pass thread cutting cycle.

When a G01 is programmed with a G29 data block, the G01 establishes the

Linear Interpolation mode for automatic multi-pass roughing cycles.

Either a G33 or a G01 has to be accompanied by a G29 data block in order

to perform any of the cycles mentioned above.

Important: The G01 code programmed in the G29 block is not modal; the

control automatically cancels the linear interpolation mode after a

multi-pass roughing cycle is completed.

Where:

Specifies:

final threading depth or roughing depth. For Absolute Programming mode (G90), this

parameter is programmed as an X axis position. For Incremental Programming mode

(G91), this parameter is programmed as a distance measured parallel to the X axis from

the initial work surface.

mode, the initial depth is programmed as an X axis position. For Incremental

Programming mode, this initial depth is programmed as a distance measured parallel to

the X axis from the initial work surface.

the distance between the starting point and the infeed endpoint on the Z axis. Not

programming a Z or programming a Z that does not create any axis motion results in a

plunge infeed. A plunge infeed moves the tool directly into the part with no Z component

in the move.

Programming a Z that is different than the starting point Z location generates a tapered

infeed. For threads that are cut with tapered infeed, the tool is fed into the part at an

angle comprised of both X and Z motions. The angle is determined by the linear

intersection of the start point and the endpoint. The endpoint is determined by this

parameter on Z axis and final depth is determined by D.

feedrate of the plunge or compound infeed. The infeed rate is programmed in the

units/inches per minute (IPM) in the inch mode, or millimeters/minute (MMPM) in the

Metric mode.

starting point. D value must always be programmed as an incremental distance,

regardless of the current operating mode.

thread lead, which is the distance the thread cutting tool is to move along the Z axis per

revolution of the spindle. The thread lead is always programmed in units of inches per

revolution (IPR) in the Inch format mode (G70), or millimeters per revolution (MMPR) in

the Metric format mode (G71).

Does not need to be programmed for roughing cycle.

thread lead for a tapered thread, which is the distance and direction the thread cutting

tool is to move along the X axis per revolution of the spindle. The thread lead is always

programmed in units of inches per revolution (IPR) in the Inch format mode (G70), or

millimeters per revolution (MMPR) in the Metric format mode (G71). The I-word

determines the angle of a tapered thread. If the angle is known, I-word can be

calculated with the following formulas:

I-word = K-word * Tan0

Assign a value to I only if cutting tapered threads (I ¹ 0).

Length of the roughing pass for Z axis roughing cycle, I is the distance along the X axis.

Does not need to be programmed for single axis roughing.

length of the thread. For Absolute Programming mode, the thread length is programmed

as the Z axis position of the end of the thread. For Incremental Programming mode, the

thread length is programmed as a distance measured parallel to the Z axis from the

infeed endpoint to the end of the thread.

Length of the roughing pass for roughing cycle, which is the distance measured parallel

to the Z axis.

pullout distance, which is the distance from the programmed end of the thread to the

point at which the thread cutting tool is to start pulling out from the workpiece. This

distance is measured parallel to the Z axis. If no L-word is programmed, then the tool

does not pull out until it reaches the programmed end of the thread. L-word must always

be programmed as an incremental distance, even in the Absolute Programming mode.

feedrate of the return path, which is the rate at which the tool moves away from the part

and returns to the start-point of the cycle for the next infeed. The infeed rate is always

programmed in units/inches per minute (IPM) in the Inch mode, or millimeters/minute

(MMPM) in the Metric mode. If no F-word is programmed in the G29 block, the last

programmed feedrate before the G28 block is used.

Offset Compatibility

Tool Length Offset

Considerations

When the control is in 7300 mode, tool length offsets are activated in the

same manner as on the 7300. The control supports 1- through 4-digit

T-words, and through AMP configuration, you have the flexibility of

specifying how the control activates offsets.

We recommend that you use this set-up when running your control in 7300

mode:

Set This Tool Length Offset Parameter:

To:

Explanation:

Tool Geometry Mode (AMP [202]):

immediate shift/immediate move

once the offset is programmed, the geometry offset

is activated immediately and the coordinate system

gets shifted immediately.

Tool Wear Mode (AMP [203]):

immediate shift/immediate move

once the offset is programmed, the wear offset is

activated immediately and the coordinate system

gets shifted immediately.

Tool Offset Cancel (AMP [204]):

cancel geometry & wear

both the geometry and wear offsets are cancelled

when the active offset is cancelled.

T-code Format (AMP [205]):

2-digit geometry & wear

The 2 right-most digits are used for geometry &

wear; and the leftover are used for tool number.

Example: T10 activates geometry offset 10 and

wear offset 10 on tool number 0.

Example: T915 activates geometry offset 15 and

wear offset 15 on tool number 9.

If the Tool Life Management option is present, set the following AMP

parameters for 7300 compatibility:

Set This Tool Length Offset Parameter:

To:

Explanation:

Tool Number/Group Boundary (AMP [131]):

9799

specify the division between ordinary tool numbers

and tool life groups.

T-word Programming Method (AMP [132]):

next Tool in T-word

for this method, the T-word to be activated is

programmed in a block that does not contain an

M06.

For systems with the Tool Life Management option, the T-word is limited

to four digits in the range of 1 to 9799.

Refer to the AMP manual for details on any of the above AMP parameters.

Important: When 7300 mode is active on the control, automatic tool

changing requires the proper PAL interface and may require changing the

AMP parameters described above. The random tool feature of the control

is also available to interface with special tool changers.

D-8

Appendix D

Allen-Bradley 7300 Series CNC

Tape Compatibility

The control has two offset tables: geometry and wear table. The sum from

these two tables is used to generate tool length data when the tool offset

number is programmed. When in 7300 mode, the active offset is also

computed as the sum of the geometry and wear offsets. Refer to chapter 3

for details.

When changing from inch to metric (or vice versa) in 7300 mode, the

control does automatic conversion on tool offset values. The 7300 did

not provide this automatic conversion and, instead, required the operator to

re-enter tool offsets.

A T-word cannot be programmed in circular interpolation mode (G02 or

G03).

Important: The control allows the Power-Turn-On (PTO) mode of the

control to be specified in AMP with respect to inch/metric (G70/G71) and

absolute/incremental (G90/G91) etc. For 7300 tape compatibility, these

parameters may need to be modified if a certain PTO mode is expected.

Refer to the AMP manual for details.

Additional Feature

In this section, we describe how to copy a 7300 tape to the control. This

process involves these steps:

Compatibility

Considerations

store a 7300 part program and pattern repeat into the control

execute the 7300 part program and patten repeat

Storing 7300 Part Programs

A 7300 tape can be stored in control memory by using the COPY

PRGRAM softkey function. While reading the tape to the control, any TN

code, which defined the program name for 7300s, is interpreted as a

comment block; this means a new program name must be entered. The

control prompts you to enter a program name for each part program or

pattern repeat stored. The name given to the program must adhere to the

format of control program names.

Important: When storing a pattern, the pattern name entered here must be

a 1-to 5-digit numeric prefixed with the letter O; for example, O10005.

Refer to section 11.5.9 for information on valid subprogram names.

At this time, the control creates an internal cross-reference table for all

pattern repeat names. The cross-reference table is generated so that any

blocks that call pattern repeat do not need to be rewritten with the new

program name. Refer to the section on Pattern Repeat for details.

You can not copy pattern repeat programs from memory to memory.

Doing so does not create the necessary cross-reference table.

D-9

Tape Compatibility

Pattern Repeat

A pattern repeat is a series of blocks of information repeated a specified

number of times for a specified function. A pattern repeat is called in 7300

mode with the following format:

(CP, name, r)#

where:

Name:

Indicates:

a pattern repeat is called.

name

the pattern blocks being called (part program name).

the number of times the pattern blocks get executed.

end of block.

You can store patterns in the control by using the COPY PRGRAM softkey

function. The control requires that a new program name be entered for

each pattern. The control automatically creates an internal cross-reference

table of 7300 pattern names. This cross-reference table consists of the

subprogram file name called by the main program, and the new file name

entered for the pattern repeat. The control takes the first program start

code from the tape and corresponds it to the file name you have just

entered for the pattern repeat; this way, you do not need to modify your

main program so that it still calls the correct pattern. This cross reference

table is maintained by the control, and it is transparent to you. For

example:

Important: The patterns called must be saved as independent part

programs and copied into control memory from a peripheral device. You

can not create new pattern repeat programs online. A maximum of 20

patterns can be copied into the controls memory.

You have a 7300 part program that has a pattern named

BL-M008-001. When you stored the part program to the control, the

control prompted you for a name; you entered O00001. The part

program and the pattern are now stored in the memory. At this point,

the control searches for the program start code on the tape and takes

the code and matches it with O00001. When this pattern name is

called, the control automatically searches the cross-reference table

for BL-M008-001 and executes O00001.

The (DP) block is saved in memory as part of the program, and it is treated

as a comment block during the execution of the part program.

Allen-Bradley 7300 Series CNC

Tape Compatibility

Executing 7300 Part Programs

The system installer has to write PAL program for the control to execute in

7300 tape compatibility mode. Refer to the PAL manual for details.

The control allows the Power-Turn-On mode (PTO) of the control to be

specified in AMP with respect to inch/metric (G70/G71) mode and

absolute/incremental (G90/G91) programming mode. For 7300 tape

compatibility, we recommend that you select G70 and G90 for PTO mode.

When 7300 tape compatibility mode is enabled, the following modal

conditions are automatically established and cannot be selected in AMP:

G36.1 Short block Acc/Dec enabled

G39.1 Tool Tip Radius Compensation Circular Transition

Important: When programming a G00 in 7300 mode, the 9/Series control

uses the <RAPID OVERRIDE> switch to override the rapid feedrate. This

applies to any programmed rapid move including moves generated by the

fixed cycles or pattern repeats. The operation of the <RAPID

OVERRIDE> switch is very PAL dependent, and can be alter by your

system installer’s PAL logic. See your system installer documentation for

details.

The part program can be executed from tape or control memory. If a 7300

program makes pattern calls, the patterns must reside in control memory.

The control attains compatible pattern repeat functionality by using an

M98 subprogram call. When the control executes the 7300 pattern repeat

call, it makes the following substitutes:

end of block.

Important: In order for the control to properly execute a M98 subprogram

call, the blocks called by the pattern repeat must be stored under a program

name starting with the letter O, followed by one through five numeric

characters. Refer to section 11.5.9 for information on valid file names.

Tape Compatibility

The main program, which has the pattern repeat call block “(CP, name, r),”

can be executed from tape or from the control memory. However, if you

want to make minor editing to your main program, you must copy the

program into the control memory. Refer to section 10.2, “Inputting Part

Programs,” for details on how to copy a program from tape.

Important: To execute a program from tape, the tape must be positioned

at the start of the main program.

For more information on how subprograms are executed in the control,

refer to chapter 10, “Subprogram Call (M98).”
