F31845 (N, A) Encoder 1 DRIVE-CLiQ: Cyclic data transfer error
Drive object: All objects
Reaction: A_INFEED: OFF2
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: DRIVE-CLiQ communications error between the Control Unit and the encoder involved.
Fault value (r0949, interpret hexadecimal):
0B: Synchronization error during alternating cyclic data transfer.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Carry out a POWER ON.
See also: p9916 (DRIVE-CLiQ data transfer error shutdown threshold slave)

F31850 (N, A) Encoder 1: Sensor Module, internal software error
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE)
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge: POWER ON
Cause: Internal software error in the Sensor Module of encoder 1.
Fault value (r0949, interpret decimal):
1: Background time slice is blocked.
2: Checksum over the code memory is not OK.
10000: OEM memory of the EnDat encoder contains data that cannot be interpreted.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: - replace the Sensor Module.
- if required, upgrade the firmware in the Sensor Module.
- contact the Hotline.

F31851 (N, A) CU DRIVE-CLiQ: Sign-of-life missing
Drive object: All objects
Reaction: A_INFEED: NONE (OFF1, OFF2)
SERVO: ENCODER (IASC / DCBRAKE, NONE)
VECTOR: ENCODER (IASC / DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communications error has occurred between the Control Unit and the Sensor Module (encoder 1)
involved. The DRIVE-CLiQ component did not set the sign of life to the Control Unit.
Fault value (r0949, interpret hexadecimal):
0A: The sign-of-life bit in the receive telegram is not set.
Remedy: Upgrade the firmware of the component involved.
