A01953 CU SYNC: Synchronization not completed
Reaction: NONE
Acknowledge: NONE
Cause: After the drive system was powered up, 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 (power off/on).
A02050 Trace: Start not possible
Reaction: NONE
Acknowledge: NONE
Cause: The trace has already been started.
Remedy: Stop the trace and, if necessary, start again.
A02055 Trace: Recording time too short
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
Reaction: NONE
Acknowledge: NONE
Cause: The selected recording clock cycle is lower than the basic clock cycle 500µs.
Remedy: Increase the value for the trace cycle.
A02057 Trace: Time slice clock cycle invalid
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.

A02058 Trace: Time slice clock cycle for endless trace not valid
Reaction: NONE
Acknowledge: NONE
Cause: The selected time slice clock cycle cannot be used for the endless trace
Remedy: Enter the clock cycle of an existing time slice with a cycle time >= 2 ms for up to 4 recording channels or >= 4 ms
from 5 recording channels per trace.
The existing time slices can be read out via p7901.

A02059 Trace: Time slice clock cycle for 2 x 8 recording channels not valid
Reaction: NONE
Acknowledge: NONE
Cause: The selected time slice clock cycle cannot be used for more than 4 recording channels.
Remedy: Enter the clock cycle of an existing time slice with a cycle time >= 4 ms or reduce the number of recording channels
to 4 per trace.
The existing time slices can be read out via p7901.
