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).
A02050 Trace: Start not possible
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The trace has already been started.
Remedy: Stop the trace and, if necessary, start again.
A02051 Trace: recording not possible as a result of know-how protection
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: TRACE recording is not possible as at least one signal or trigger signal being used is under know-how protection.
Alarm value (r2124, interpret decimal):
1: Recorder 0
2: Recorder 1
3: Recorders 0 and 1
Remedy: - Temporarily activate or deactivate know-how protection (p7766).
- include the signal in the OEM exception list (p7763, p7764).
- Where relevant do not record the signal.

A02055 Trace: Recording time too short
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The trace duration is too short.
The minimum is twice the value of the trace clock cycle.
Remedy: Check the selected recording time and, if necessary, adjust.
A02056 Trace: Recording cycle too short
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The selected recording cycle is shorter than the selected basic clock cycle 0 (p0110[0]).
Remedy: Increase the value for the trace cycle.
A02057 Trace: Time slice clock cycle invalid
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The time slice clock cycle selected does not match any of the existing time slices.
Remedy: Enter an existing time slice clock cycle. The existing time slices can be read out via p7901.
