Remedy: - carry-out a POWER ON.
- check whether the firmware version of the encoder (r0148) matches the firmware version
of control unit (r0018).
231887 <location>CU DRIVE-CLiQ: Component faulted
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: ENCODER (DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: Fault detected on the DRIVE-CLiQ component involved. Faulty hardware cannot be
excluded.
Fault value (r0949, hexadecimal):
20: Error in the telegram header.
23: Receive error: The telegram buffer memory contains an error.
42: Send error: The telegram buffer memory contains an error.
43: Send error: The telegram buffer memory contains an error.
60: Response received too late during runtime measurement.
61: Time taken to exchange characteristic data too long.
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.
231895 <location>CU DRIVE-CLiQ: Cyclic data transfer error
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: ENCODER (DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: DRIVE-CLiQ communications error between the control unit and the encoder involved.
Fault value (r0949, hexadecimal):
0B: Synchronization error during alternating cyclic data transfer.
Remedy: - carry-out a POWER ON.

231896 <location>CU DRIVE-CLiQ: Inconsistent component properties
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: OFF2 (DCBRAKE, ENCODER, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: The properties of the DRIVE-CLiQ component, specified by the fault value, have changed
in an incompatible fashion with respect to the run-up. One cause can be, e.g. that a DRIVE-
CLiQ cable or DRIVE-CLiQ component has been replaced.
Fault value (r0949, decimal):
Component ID.
Remedy: - when replacing cables, only use cables with the same length as the original cables.
- when replacing components, use the same components and firmware releases.
- carry-out a POWER ON.
231897 <location>DRIVE-CLiQ: No communications to the components
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: ENCODER (DCBRAKE, NONE, OFF1, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Communications with the DRIVE-CLiQ component specified by the fault value is not
possible.
One cause can be, e.g. that a DRIVE-CLiQ cable has been withdrawn.
Fault value (r0949, decimal):
Component ID.
Remedy: - check the DRIVE-CLiQ connections.
- carry-out a POWER ON.
