Trace: Pretrigger Time Too Long; Trace: Parameterization Deleted Due To Unit Changeover; Trace: Insufficient Control Unit Memory; Cu: Computing Dead Time Current Controller Too Short - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
202075 <location>Trace: Pretrigger time too long
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The selected pretrigger time must be shorter than the trace time.
See also: p4721 (Trace recording time), p4722 (Trace trigger delay)
Remedy: Check the pretrigger time setting and change if necessary.
202080 <location>Trace: Parameterization deleted due to unit changeover
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The trace parameterization in the drive unit was deleted due to a unit changeover or a change in the reference param-
eters.
Remedy: Restart trace.
202099 <location>Trace: Insufficient Control Unit memory
Message value: -
Drive object: All objects
Reaction: NONE
Acknowledge: NONE
Cause: The memory space still available on the Control Unit is no longer sufficient for the trace function.
Remedy: Reduce the memory required, e.g. as follows:
- reduce the trace time.
- increase the trace clock cycle.
- reduce the number of signals to be traced.

202100 <location>CU: Computing dead time current controller too short
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: NONE
Acknowledge: NONE
Cause: The value in p0118 produces a dead time of one clock cycle because it is prior to setpoint availability. A possible cause
could be, for example, that the system characteristics no longer match those parameterized after a component has
been replaced.
Alarm value (r2134, floating point):
The minimum value for p0118 where a dead time no longer occurs.
Remedy: - set p0118 to a value greater than or equal to the alarm value.
- set p0117 to an automatic setting.
- check the firmware releases of the components involved.
