1000

The check timer has expired while the change timer has still not expired. If, in a monitoring channel, an SGE

change (e.g. SBH is selected), then the so-called change timer is started (timer value = MD36950/p9550).

In addition, what is known as a checking timer is started in the other channel (timer value = 10xMD36950).

While the change timer is running, if the same SGE is changed again, the timer value is extended and the check

timer in the other channel only runs once.

If the change timer is extended so often that the run time is greater than for the check timer then the fault is

output.

Too many signal changes were detected during the checking timer runtime.

Remedy

Determine the SGE involved and the associated hardware signal and investigate the situation. There may be

contact problems at the sensor (e.g. poor contact) or there were too many switching operations. If necessary,

the behavior can be improved by changing the timer setting.

1002

The user agreement is not consistent: The status of the user agreement is, after 4 s has expired, different for both

monitoring channels.

%3 = status of the user agreement, NCK.

%4 = status of the user agreement, drive.

This effect can occur if the user agreement is only set or reset through one channel. An additional fault cause

is that if the F-code 1003 only occurs in one monitoring channel and then the user agreement is only withdrawn

through one channel. This means that code 1002 is then the result of a code 1003 only in one channel.

Remedy

User agreement expired

1003

When the user agreement is set, the difference between the newly determined reference point (NC actual value)

after booting (absolute value encoder) or reference point approach [homing] (distance-coded or incremental

measuring system) and the safe actual position (saved value + traversing distance) is greater than the reference

tolerance MD36944/p9544. In this case, the user agreement is withdrawn.

Remedy

Check the mechanical system of the axis - it is possible that the axis was moved when powered-down and the

actual value last saved by the control no longer corresponds with the new value the next time the system is

booted. It is also possible that the tolerance window for the test has been set too narrow. The cause should be

determined and after checking the actual values the user agreement can be again reset after an NCK-RESET.

Axis %1 error in a monitoring channel, Code%2, values: NCK%3, drive %4

1004

Violated plausibility, user agreement

• Although the user agreement was already set, an attempt was made to set it again.

• The user agreement is set although the axis has still not been referenced.

Remedy

Violated plausibility, user agreement

1005

When activating the SGEs test stop selection, the switch-off signal path test cannot be carried out because the

pulses have already been cancelled.

Remedy

Check the start conditions for carrying out the test, and if required correct. In the commissioning phase, it is also

possible that there is incorrect parameterization (or wiring) for the feedback signal regarding pulse cancellation.

1009

After activating the SGE test stop selection, the pulses have still not been cancelled after timer MD36957

$MA_SAFE_PULSE_DIS_CHECK_TIME has elapsed.

Remedy

Check the parameterization for the timer - it is possible that the value has been selected too low.

Axis %1 difference safe input %2, NCK %3, drive %4

Parameter

%1 = axis name, spindle number

%2 = monitoring function involved

%3 = interface identifier, NCK input

%4 = interface identifier, drive input

Explanation

A difference has been detected at the specified safe input. The state of the specified input signal differs in the

two monitoring channels NCK and drive during the time set in MD36950 $MA_SAFE_MODE_SWITCH_TIME.

Monitoring function involved (%2):

SS/SV difference in SGE "deselect Safe Operating Stop / safely reduced speed"

SS difference in SGE "deselect Safe Operating Stop"

SV difference in SGE "select safely reduced speed"

SP difference in SGE "select safe limit positions"

SVOVR difference in SGE "select SG corrections"

Interface identifier NCK input (SPL interface):

<io> = parameterized system variable range (01=$A_INSID, 02=$A_INSED)

<dword> = system variable - double word (1,2)

<bit> = bit number in the system variable double word (1...32)

<value> = value of the NCK-SGE (0,1)

Interface identifier, drive input (%4):

DBX<byte><bit>=<value>

<byte> = byte number in the axis-specific DB (22, 23, 32, 33)

<bit> = bit number in the byte (0...7)

<value> = value of the drive SGE (0,1)

This alarm can be suppressed using the MD10096 $MN_SAFE_DIAGNOSIS_MASK, bit 0=0.

Axis %1 error for crosswise data comparison: Static actual value difference

Parameter

%1 = axis name, spindle number

Explanation

A difference in the actual values was detected using the crosswise data comparison between NCK and drive

monitoring channel. This difference is greater than the maximum tolerance defined in MD36942

$MA_SAFE_POS_TOL. This can be checked using the safe position actual values of the two monitoring channels

displayed in the service screen. The alarm is only displayed, if monitoring with absolute reference (SE/SN) has

been enabled for the specified axis and if the user agreement has been set. The alarm is cleared as soon as the

user agreement is deleted or the actual difference between the two monitoring channels again drops below the

maximum permissible difference.

27005

Axis %1 error for crosswise data comparison: Static actual value difference

Remedy

The user agreement must be deleted if the alarm is present as a steady-state alarm. When the control has been

rebooted, the machine can be brought into the safe state again, and operation resumed by a new referencing

process and setting the user agreement.

Prior to setting the user agreement, the actual position of the axis displayed in the "User enable" screen must

be compared with the current machine position. This is absolutely necessary to ensure proper functioning of

the safe limit positions (SE) and Safe Cams (SN).

The user agreement can only be changed in key-actuated switch setting 3 or after entering a password.

Axis %1 acceptance test mode is active

Parameter

%1 = axis name, spindle number

Explanation

An SI acceptance test has been started with the acceptance test wizard at the operator panel. The acceptance

test mode is activated for the NCK and drive for the duration of this acceptance test. In the acceptance test

mode, SI power on alarms can be acknowledged with the reset button.

Response

Alarm display, on the NCK side, the alarm criterion of SI-POWER ON alarms is changed over to reset-acknowl-

edgeable.

Remedy

Deselect the acceptance test using the acceptance test Wizard or wait until it has been completed (the duration

of the acceptance test can be parameterized using MD36958 $MA_SAFE_ACCEPTANCE_TST_TIMEOUT).

Axis %1 safely reduced speed exceeded

Parameter

%1 = axis name, spindle number

Explanation

The axis has moved too quickly and faster than that specified in MD36931 $MA_SAFE_VELO_LIMIT. If function

"correction, safely reduced speed" in MD36901 $MA_SAFE_FUNCTION_ENABLE is enabled, then for SG2 and

SG4, the active correction value from MD36932 $MA_SAFE_VELO_OVR_FACTOR[0...15] must be taken into

account for the permissible speed.

Parameter

%1 = axis name, spindle number

%2 = MD name

%3 = MD field index for MD name

%4 = error code, note regarding the cause

Explanation

The parameterization of the machine data is incorrect. An additional indication is the field index of the machine

data. If the machine data is a single item of machine data, a zero is specified as a field index. This alarm occurs

in the following contexts:

•

1: The conversion of the specified MD into the internal computation format resulted in an overflow.

•

2: Error when parameterizing the input/output assignments for SGE/SGA.

•

3: One of the activated cam positions is outside the actual value modulo range.

•

4: The function "actual value synchronization 2-encoder system" (slip) is selected for a single-encoder

system.

•

5: The function "actual value synchronization 2-encoder system" (slip) is simultaneously selected with a

function with absolute reference (SE/SN).

•

6: A safety function was enabled in MD36901 $MA_SAFE_FUNCTION_ENABLE without the safety functions

SBH/SG having been enabled.

•

7: An axis-specific SGE/SGA was parameterized at the SPL interface (segment number = 4) and the function

enable for the external stops is missing (MD36901 $MA_SAFE_FUNCTION_ENABLE, bit 6).

•

8: In MD36901 $MA_SAFE_FUNCTION_ENABLE using bit 7 cam synchronization is activated, without the

cams having been enabled using bits 8...15.

•

12: A zero was entered in MD36917 $MA_SAFE_ENC_GRID_POINT_DIST.

inverted (bit 31 = 1) or the SGE "Deselect ext. STOP A" was not parameterized at the SPL interface $A_OUTSI.

•

16: MD10097 $MN_SAFE_SPL_STOP_MODE was parameterized to a value of 4 (Stop E) without having

enabled the external Stop E in all axes with SI function enable signals (MD36901 $MA_SAFE_FUNC-

TION_ENABLE not equal to 0).

•

was assigned for several axes.

•

18: It was not possible to internally pre-assign MD36919 $MA_SAFE_ENC_PULSE_SHIFT from the drive

parameterization in the drive.

•

19: MD36932 $MA_SAFE_VELO_OVR_FACTOR was parameterized with decimal places.

•

20: The values entered in MD36934 $MA_SAFE_POS_LIMIT_PLUS and MD36935 $MA_SAFE_POS_LIM-

Explanation

For cyclic crosswise data comparison between the NCK and PLC differences have occurred in the data that are

being compared. Parameter %1 specifies the incorrect system variable ($A_INSI, $A_OUTSI, $A_INSE,

$A_OUTSE or $A_MARKERSI) with field index %2.

Special cases:

• Display "Error for crosswise Data comparison NCK-PLC, $MN_PREVENT_SYNACT_LOCK[0], ..." means that

the SPL commissioning status is set differently in the NCK and PLC.

• Display "Error for crosswise Data comparison NCK-PLC, $MN_SPL_STOP_MODE[0], ..." means that the SPL

stop response (Stop D or E) is set differently in the NCK and PLC.

• Display "Error for crosswise Data comparison NCK-PLC, TIMEOUT[0], NCK: 0” means that there is a critical

communication error between the NCK and PLC - and crosswise data comparison cannot be performed.

• Display "Error for crosswise Data comparison NCK-PLC, $MN_SAFE_SPL_USER_DATA[n], ..." means that the

user data are set differently in the NCK and PLC.

• Display "Error for crosswise Data comparison NCK-PLC, $A_FRDP_SUBS[n], $A_FRDP_ERR_REAC[n], ..."

means that the specified system variables are different in the NCK and PLC.

Using parameter %4, a specific alarm message can be configured on the HMI for each of the listed system

%1 SPL protection not activated

Parameter

%1 = name of the component for which the protection is not activated (NCK or PLC)

Explanation

The protective mechanisms for the SPL have not been activated. The commissioning phase of the SPL has not

yet been completed. For an error in the crosswise data comparison between NCK and PLC, a stop response (Stop

D or E) is not initiated.

Response

Alarm display

Remedy

Remedy for NCK: Activate the protective mechanisms by writing to MD11500 $MN_PREVENT_SYNACT_LOCK

[0,1]. The number range of the synchronized action IDs used in the SPL must be entered in this MD.

Remedy for the PLC: Activate the protective mechanisms by setting the appropriate data bit in DB18.

27096

SPL start not allowed

Parameter

Explanation

To start the SPL in the protected state (MD11500 $MN_PREVENT_SYNACT_LOCK[0,1] not equal to 0), at least

one axis must have Safety Integrated functionality activated (via MD36901 $MA_SAFE_FUNCTION_ENABLE)

beforehand, and operated with active drive.

In addition, at least one SGE/SGA of this axis must have been parameterized at an SPL interface. Without this

functionality it is only permissible to operate the SPL in the commissioning state.

This alarm can be suppressed using MD10096 $MN_SAFE_DIAGNOSIS_MASK, bit 1 = 1.

Response

Alarm display

Remedy

Find the reason why SPL did not start. Possible causes could be:

• There is either an NC or drive fault (e.g. after replacing an encoder, Emergency Stop, PROFIsafe alarms)

• There is a syntax error in the SPL itself

• A safety alarm is present (e.g. "safe end position exceeded")

• At PROG_EVENT start, the name or path of the SPL was not correctly written to; observe upper and lower

case letters

• Simultaneous start of an ASUB and PROG_EVENT, parameterizing MD11602 (stop reasons, read-in inhibit)

• Problems when calling FB4/FC9

Switch control system OFF and ON again.

At least one axis is not safely referenced

Parameter

Explanation

There are two reasons for this alarm:

• the machine position of at least one of the axes monitored with SI has not been acknowledged by the user

• the machine position of at least one of the axes monitored with SI has still not been verified by subsequent

referencing

Even if the axis is already referenced there is no acknowledgement that referencing has supplied the correct

result. For example, incorrect results can occur if the axis was moved after the control was powered-down - with

the result that the stop position saved prior to powering-down is no longer correct.

To ensure that this does not happen, the user must acknowledge the displayed actual position after the first

referencing operation. After the user agreement has been set for the first time, the axis must be subsequently

referenced each time that the control is booted (with absolute encoders, this subsequent referencing is auto-

matically executed). This procedure is carried out to verify the stop position saved prior to powering-down the

control.

The alarm display can be set in MD10094 $MN_SAFE_ALARM_SUPPRESS_LEVEL (MD < 3) in such a way that

incorrect referencing is displayed separately for each axis.

Response

Alarm display

The SGA "axis safely referenced" is not set. SE is disabled if the safe actual position has not yet been acknowl-

edged by the user agreement. If the user agreement is set, SE remains active. The Safe Cams are calculated and

output, but their significance is limited because referencing has not been acknowledged.

Remedy

Move all of the SI axes to the known positions and change into the "Referencing" mode. Check the positions on

the machine displayed in the user agreement screen and set the "User agreement" using the selection/toggle

key.

If the user agreement has already been set for the axis, then re-reference the axes. The user agreement can only

be changed in key-actuated switch setting 3 or after entering a password.

Program con-

The alarm is no longer displayed when the alarm cause has been removed. No other operator actions are

Axis %1 hardware encoder fault of the safety-related actual value

Parameter

%1 = axis name, spindle number

Explanation

The encoder evaluation signals a hardware fault.

The following causes are possible:

Dirty optical encoder evaluation

Signal transfer problems

Missing encoder number after replacing the encoder (involves encoders with serial number, built-in motors or

third-party motors)

Response

Alarm display

In addition, a STOP F is initiated, that can result in the subsequent Alarm 27001 with fault IDs 0, 27023 and

Waiting for Motor Module for at least one axis

Parameter

Explanation

Alarm when booting as long as the Motor Module of at least one axis is still not ready for SI. When booting,

communications to the Motor Module have still not been established as the safety functions for at least one axis

are still not available.

The alarm display can be set in MD10094 $MN_SAFE_ALARM_SUPPRESS_LEVEL (MD < 3) in such a way that it

can be individually displayed as to whether communications have already been established for each axis. The

alarm is continuously active when booting if at least one drive does not communicate. Otherwise, the alarm is

only briefly active - and is then automatically cleared again.

Possible causes for the alarm being permanently present:

• The safety motion monitoring functions are only activated in MD36901 $MA_SAFE_FUNCTION_ENABLE,

however, not in the corresponding parameter of the associated drive (p9501).

• The axis → drive assignment via MD36906 $MA_SAFE_CTRLOUT_MODULE_NR, 10393

$MN_SAFE_DRIVE_LOGIC_ADDRESS or p0978 is incorrect

• PROFIBUS connector fallen out.

Response

always starts with 2.

For example, this means that F01600 is then called 201600. In this Chapter, faults and alarms

are described with numbers from the SINAMICS environment.

In the HMI environment, faults and alarms are treated like alarms.

Differences between faults and alarms

Type

Description

Faults

What happens when a fault occurs?

• The appropriate fault response is initiated.

• Status signal ZSW1.3 is set.

• The fault is entered in the fault buffer.

How are the faults eliminated?

• Remove the cause of the fault.

• Acknowledge the fault.

Alarms

What happens when an alarm occurs?

• Status signal ZSW1.7 is set.

• The alarm is entered into the alarm buffer.

How are alarms eliminated?

• Alarms are self acknowledging, that is, they are reset automatically when

the cause of the alarm has been eliminated.

Fault responses

The standard fault responses according to PROFIdrive, that are used for safety, are described in

the following table. The OFF2 fault response is used as additional stopping measure while the

pulses are safely cancelled via the safety-related switch-off signal paths.

Acknowledging faults

The list of faults and alarms specifies how to acknowledge each fault after the cause has been

eliminated.

List

Description

POWER ON

The fault is acknowledged by a POWER ON (switch drive unit off and on again).

Note:

If the fault cause has still not been resolved, then the fault is immediately displayed again after booting.

Re-establishing communications to the NCK or PLC after a communication failure has been detected to this

component is an exception. In this case, just the same as for a normal boot, the failsafe values are activated,

however the alarms present are acknowledged for a new communication failure.

IMMEDIATE-

Starting from a drive object, the fault can be acknowledged by the following methods:

1. Acknowledge via setting parameter:

p3981 = 0 → 1

2. Acknowledge via binector inputs:

p2103 BI: 1. Acknowledge faults

p2104 BI: 2. Acknowledge faults

p2105 BI: 3. Acknowledge faults

3. Acknowledging via a PROFIBUS control signal:

STW1.7 = 0 → 1 (signal edge)

Note:

• This fault can also be acknowledged using POWER ON.

• If the cause of the fault has not been removed the fault is not cleared after acknowledgment.

• Faults from SH/SBC

The "Safe Standstill" (SH) function must be deselected before acknowledging these faults.

READY TO

The fault can only be acknowledged in the READY state.

OPERATE

In this state, the DC link is charged and the pulses are inhibited.

ment

Explanation

The "Safety Integrated" function integrated in the drive on the Control Unit has detected a fault and initiated

a STOP A (STO via the safety switch-off signal path of the Control Unit).

• Forced checking procedure of the safety switch-off signal path of the Control Unit unsuccessful.

• Subsequent response to fault F01611 (defect in a monitoring channel).

Fault value (r0949, interpret decimal):

0: Stop request from monitoring channel 2

1005: STO active, although STO not selected and there is no internal STOP A present.

1010: STO inactive although STO is selected or an internal STOP A is present.

9999: Subsequent response to fault F01611.

Remedy

Select safe standstill and then deselect again.

- replace the Motor Module involved.

For fault value = 9999:

- carry out diagnostics for the active fault F01611.
