231885 <location>Encoder 1 DRIVE-CLiQ (CU): Cyclic data transfer error
Message value: Component number: %1, fault cause: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred from the Sensor Module (encoder 1) involved to the Control Unit.
The nodes do not send and receive in synchronism.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 1A hex = 26 dec:
Sign-of-life bit in the receive telegram not set and the receive telegram is too early.
xx = 21 hex = 33 dec:
The cyclic telegram has not been received.
xx = 22 hex = 34 dec:
Timeout in the telegram receive list.
xx = 40 hex = 64 dec:
Timeout in the telegram send list.
xx = 62 hex = 98 dec:
Error at the transition to cyclic operation.
Remedy: - check the power supply voltage of the component involved.
- carry out a POWER ON.
- replace the component involved.

231886 <location>Encoder 1 DRIVE-CLiQ (CU): Error when sending DRIVE-CLiQ data
Message value: Component number: %1, fault cause: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred from the Sensor Module (encoder 1) involved to the Control 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.
- check whether the firmware version of the encoder (r0148) matches the firmware version of Control Unit (r0018).
231887 <location>Encoder 1 DRIVE-CLiQ (CU): Component fault
Message value: Component number: %1, fault cause: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: Fault detected on the DRIVE-CLiQ component involved (Sensor Module for encoder 1). 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.
