Faults and Alarms
List of faults and alarms
Remedy:
Re alarm value = 1:
- check the motor parameters.
- carry-out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 0.25).
Re alarm value = 2, 5:
Adapt the speed setpoint (p1965) or minimum limiting (p1080).
Re alarm value = 3, 6:
Adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
Re alarm value = 4, 7:
Adapt the speed setpoint (p1965) or maximum limiting (p1082, p1083 and p1086).
Note:
The moment of inertia identification routine can be disabled using p1959.2.

A07985
Drive: Speed controller optimization, vibration test
Reaction:
NONE
Acknowledge:
NONE
Cause:
A fault has occurred during the vibration test.
Alarm value (r2124, decimal):
1: The speed did not reach a steady-state condition.
2: The speed setpoint was not able to be approached as the minimum limiting is active.
3. The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
4. The speed setpoint was not able to be approached as the maximum limiting is active.
5: Torque limits too low for a torque step.
6: No suitable speed controller setting was found.
Remedy:
Re alarm value = 1:
- check the motor parameters.
- carry-out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 0.25).
Re alarm value = 2:
Adapt the speed setpoint (p1965) or minimum limiting (p1080).
Re alarm value = 3:
Adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
Re alarm value = 4:
Adapt the speed setpoint (p1965) or maximum limiting (p1082, p1083 and p1086).
Re alarm value = 5:
Increase the torque limits (e.g. p1520, p1521).
Re alarm value = 6:
Reduce the dynamic factor (p1967).
Note:
The speed controller vibration test can be disabled using p1959.4.

F07986
Drive: Speed controller optimization, ramp-function generator
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
Problems with the ramp-function generator have occurred during the automation speed controller optimization rou-
tine.
Fault value (r0949, decimal):
1: The positive and negative direction of rotation is inhibited.
Remedy:
Re fault value = 1:
Enable the direction of rotation (p1110 or p1111).
A07987
Drive: Speed controller optimization, no encoder available
Reaction:
NONE
Acknowledge:
NONE
Cause:
No encoder available. The automatic speed controller optimization routine is carried-out without encoder (sensor-
less).
Alarm value (r2124, decimal):
1: An encoder is not connected.
2: It involves a SINAMICS G drive unit that only supports sensorless closed-loop control.
