4 Faults and alarms
4.2 List of faults and alarms
Remedy: Carry out a POWER ON.
F34887 VSM DRIVE-CLiQ (CU): Component fault
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY
Cause: Fault detected on the DRIVE-CLiQ component (Voltage Sensing Module) involved. Faulty hardware cannot be
excluded.
Fault cause:
32 (= 20 hex):
Error in the telegram header.
35 (= 23 hex):
Receive error: The telegram buffer memory contains an error.
66 (= 42 hex):
Send error: The telegram buffer memory contains an error.
67 (= 43 hex):
Send error: The telegram buffer memory contains an error.
96 (= 60 hex):
Response received too late during runtime measurement.
97 (= 61 hex):
Time taken to exchange characteristic data too long.
Note regarding the message value:
The individual information is coded as follows in the message value (r0949/r2124):
0000yyxx hex: yy = component number, xx = error cause
Remedy: - check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
- check the electrical cabinet design and cable routing for EMC compliance
- if required, use another DRIVE-CLiQ socket (p9904).
- replace the component involved.
F34895 VSM DRIVE-CLiQ (CU): Alternating cyclic data transfer error
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: NONE (OFF1, OFF2)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred from the Voltage Sensing Module involved (VSM) to the Control
Unit.
Fault cause:
11 (= 0B hex):
Synchronization error during alternating cyclic data transfer.
Note regarding the message value:
The individual information is coded as follows in the message value (r0949/r2124):
0000yyxx hex: yy = component number, xx = error cause
Remedy: Carry out a POWER ON.

F34896 VSM DRIVE-CLiQ (CU): Inconsistent component properties
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3, STOP2)
Acknowledge: IMMEDIATELY
Cause: The properties of the DRIVE-CLiQ component (Voltage Sensing Module), specified by the fault value, have changed
in an incompatible fashion with respect to the properties when booted. One cause can be, e.g. that a DRIVE-CLiQ
cable or DRIVE-CLiQ component has been replaced.
Fault value (r0949, interpret decimal):
Component number.
