Siemens SINAMICS S210 - Clock Cycle Synchronous Operation Synchronization Unsuccessful; CU SYNC: Synchronization Application Clock Cycle Missing; CU DRIVE-Cliq: Synchronization of Component Not Supported

Cause: At this drive object, the connection to at least one Publisher for PROFIBUS peer-to-peer data transfer in cyclic operation
has been aborted.
Fault value (r0949, interpret binary):
Bit 0 = 1: Publisher with address in r2077[0], connection aborted.
...
Bit 15 = 1: Publisher with address in r2077[15], connection aborted.
Remedy: - check the PROFIBUS cables.
- check the state of the Publisher that has the aborted connection.
Reaction upon A: NONE
Acknowl. upon A: NONE
F01950 (N, A) PB/PN: clock cycle synchronous operation synchronization unsuccessful
Message value: -
Drive object: All objects
Reaction: OFF1 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Synchronization of the internal clock cycle to the global control telegram has failed. The internal clock cycle exhibits an
unexpected shift.
Remedy: Only for internal Siemens troubleshooting.
Note:
PB: PROFIBUS
PN: PROFINET
Reaction upon N: NONE
Acknowl. upon N: NONE
Reaction upon A: NONE
Acknowl. upon A: NONE
F01951 CU SYNC: Synchronization application clock cycle missing
Message value: %1
Drive object: All objects
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: If DRIVE-CLiQ components with different application clock cycle are operated on a DRIVE-CLiQ port, this requires
synchronization with the Control Unit. This synchronization routine was unsuccessful.
Fault value (r0949, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: - carry out a POWER ON (switch-off/switch-on) for all components.
- upgrade the software of the DRIVE-CLiQ components.
- upgrade the Control Unit software.
Note:
If a Controller Extension is being used (e.g. CX32, NX10), then the following applies:
Check whether the Controller Extension is issuing error messages, and if required, remove these.
F01952 CU DRIVE-CLiQ: Synchronization of component not supported
Message value: %1
Drive object: All objects
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
