Message class: Communication error to the higher-level control system (9)
Reaction: OFF1 (NONE, OFF2, OFF3)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: 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.

F01951 CU SYNC: Synchronization application clock cycle missing
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY (POWER ON)
Cause: Internal synchronization of the application cycles 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 Control Unit software.
A01953 CU SYNC: Synchronization not completed
Message class: Internal (DRIVE-CLiQ) communication error (12)
Reaction: NONE
Acknowledge: NONE
Cause: After the drive system was switched on, synchronization between the basic clock cycle and application clock cycle
was started but was not completed within the selected time tolerance.
Alarm value (r2124, interpret decimal):
Only for internal Siemens troubleshooting.
Remedy: Carry out a POWER ON (switch-off/switch-on).
