Siemens SINAMICS G120 - F07435 (N) Drive: Setting the ramp-function generator for sensorless vector control; A07444 PID autotuning is activated; F07445 PID autotuning canceled; A07530 Drive: Drive Data Set DDS not present

4 Faults and alarms
4.2 List of faults and alarms
SINAMICS G120 Control Units CU240B-2/CU240E-2
832 List Manual (LH11), 01/2016, A5E33839529
Remedy: For alarm value = 1:
Set the output limit in p2291 higher than in p2292.
See also: p2291 (Technology controller maximum limiting), p2292 (Technology controller minimum limiting)
F07435 (N) Drive: Setting the ramp-function generator for sensorless vector control
Message class: Application/technological function faulted (17)
Reaction: OFF2 (IASC/DCBRK, NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: During operation with sensorless vector control (r1407.1) the ramp-function generator was stopped (p1141). An
internal setting command of the ramp-function generator output caused the set setpoint speed to be frozen.
Remedy: - de-activate the holding command for the ramp-function generator (p1141).
- suppress the fault (p2101, p2119). This is necessary if the ramp-function generator is held using jogging and the
speed setpoint is simultaneously inhibited (r0898.6).
A07444 PID autotuning is activated
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: NONE
Cause: Automatic setting of the PID controller parameters (PID autotuning) was activated (p2350).
See also: p2350 (Enable PID autotuning)
Remedy: Not necessary.
This alarm is automatically withdrawn after the PID autotuning has been completed.
F07445 PID autotuning canceled
Message class: Application/technological function faulted (17)
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: The PID autotuning was canceled as a result of an error.
Remedy: - increase the offset.
- check system configuration.
A07530 Drive: Drive Data Set DDS not present
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The selected drive data set is not available (p0837 > p0180). The drive data set was not changed over.
See also: p0180 (Number of Drive Data Sets (DDS)), p0820 (Drive Data Set selection DDS bit 0), p0821 (Drive Data
Set selection DDS bit 1), r0837 (Drive Data Set DDS selected)
Remedy: - select the existing drive data set.
- set up additional drive data sets.
A07531 Drive: Command Data Set CDS not present
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The selected command data set is not available (p0836 > p0170). The command data set was not changed over.
See also: p0810 (Command data set selection CDS bit 0), p0811 (Command data set selection CDS bit 1), r0836
(Command Data Set CDS selected)
Remedy: - select the existing command data set.
- set up additional command data sets.
