Overview of Alarms
SINAMICS-Alarms
Cause: A DRIVE-CLiQ communications error has occurred from the controller extension involved to the Con-
trol Unit.
Data were not able to be sent.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 41 hex:
Telegram type does not match send list.
Remedy: Carry out a POWER ON.
240887 <location>CX32 DRIVE-CLiQ (CU): Component fault
Message Component number: %1, fault cause: %2
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: Fault detected on the DRIVE-CLiQ component involved. Faulty hardware cannot be excluded.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 20 hex:
Error in the telegram header.
xx = 23 hex:
Receive error: The telegram buffer memory contains an error.
xx = 42 hex:
Send error: The telegram buffer memory contains an error.

xx = 61 hex:
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>CX32 DRIVE-CLiQ (CU): Cyclic data transfer error
Message Component number: %1, fault cause: %2
value:
Drive object: All objects
Reaction: OFF2
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred from the controller extension involved to the Con-
trol Unit.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 0B hex:
Synchronization error during alternating cyclic data transfer.
Remedy: Carry out a POWER ON.

249150 <location>Cooling system: Fault occurred
Message -
value:
Drive object: A_INF, B_INF, S_INF, SERVO, VECTOR
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 device for the cooling system.
