240887 <location>CU DRIVE-CLiQ: Component faulted
Reaction: OFF2
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.
240895 <location>CU DRIVE-CLiQ: Cyclic data transfer error
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred between the control unit and the
controller extension involved.
Fault value (r0949, hexadecimal):
0B: Synchronization error during alternating cyclic data transfer.
Remedy: - carry-out a POWER ON.

249150 <location>Cooling system: Fault occurred
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The cooling system signals a general fault.
Remedy: - check the wiring between the cooling system and the input terminal (terminal module).
- check the external control unit for the cooling system.
See also: p0266
249151 <location>Cooling system: Conductivity has exceeded the fault
threshold
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The conductivity of the cooling water has exceeded the selected fault threshold (p0269[2]).
See also: p0266
Remedy: Check the device to de-ionize the cooling water.
249152 <location>Cooling system: ON command, feedback signal missing
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: The feedback signal of the ON command of the cooling system is missing.
- after the ON command, the feedback signal has not been received within the selected
starting time (p0260).
- the feedback signal has failed in operation.
See also: p0260, r0267
Remedy: - check the wiring between the cooling system and the input terminal (terminal module).
- check the external control unit for the cooling system.
