Encoder 3 Drive-Cliq (Cu): Alternating Cyclic Data Transfer Error; Encoder 3 Drive-Cliq (Cu): Inconsistent Component Properties; Encoder 3: Unknown Fault - Siemens Sinamics S120 Diagnostic Manual

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.
233895 <location>Encoder 3 DRIVE-CLiQ (CU): Alternating cyclic data transfer error
Message value: Component number: %1, fault cause: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred from the Sensor Module (encoder 3) involved to the Control 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.

233896 <location>Encoder 3 DRIVE-CLiQ (CU): Inconsistent component properties
Message value: Component number: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF2 (IASC/DCBRAKE, NONE, OFF1, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY
Cause: The properties of the DRIVE-CLiQ component (Sensor Module for encoder 3), specified by the fault value, have
changed in an incompatible fashion with respect to the properties when booted. One cause can be, e.g. that a DRIVE-
CLiQ cable or DRIVE-CLiQ component has been replaced.
Fault value (r0949, interpret decimal):
Component number.
Remedy: - carry out a POWER ON.
- when a component is replaced, the same component type and if possible the same firmware version should be used.
- when a cable is replaced, only cables whose length is the same as or as close as possible to the length of the original
cables should be used (ensure compliance with the maximum cable length).
233899 <location>Encoder 3: Unknown fault
Message value: New message: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: OFF1 (IASC/DCBRAKE, NONE, OFF2, OFF3, STOP1, STOP2)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: A fault occurred on the Sensor Module for encoder 3 that cannot be interpreted by the Control Unit firmware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Fault value (r0949, interpret decimal):
Fault number.
Note:
If required, the significance of this new fault can be read about in a more recent description of the Control Unit.
Remedy: - replace the firmware on the Sensor Module by an older firmware version (r0148).
- upgrade the firmware on the Control Unit (r0018).
