Overview of Alarms
SINAMICS-Alarms
Cause: A DRIVE-CLiQ communication error has occurred form the Control Unit to the power unit involved.
The nodes do not send and receive in synchronism.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 21 hex:
The cyclic telegram has not been received.
xx = 22 hex:
Timeout in the telegram receive list.
xx = 40 hex:
Timeout in the telegram send list.
Remedy: - carry out a POWER ON.
- replace the component involved.

Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred form the Control Unit to the power unit involved.
Data were not able to be sent.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 41 hex:

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 = 43 hex:
Send error: The telegram buffer memory contains an error.
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.
