Remedy:
For fault value = 1:
- check the motor parameters (rating plate data). After the change: Calculate p0340 = 3.
- check the moment of inertia (p0341, p0342). After the change: Calculate p0340 = 3.
- carry out a motor data identification routine (p1910).
- if required, reduce the dynamic factor (p1967 < 25 %).
For fault value = 2:
- adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
For fault value = 3:
- adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
For fault value = 4:
- adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086).
For fault value = 5:
- increase the torque limits (e.g. p1520, p1521).
For fault value = 6:
- reduce the dynamic factor (p1967).
- disable the vibration test (p1959.4 = 0) and repeat the rotating measurement.

F07986
Drive: Rotating measurement ramp-function generator
Reaction:
OFF1 (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
During the rotating measurements, problems with the ramp-function generator occurred.
Fault value (r0949, interpret decimal):
1: The positive and negative directions are inhibited.
Remedy:
For fault value = 1:
Enable the direction (p1110 or p1111).
F07988
Drive: Rotating measurement, no configuration selected
Reaction:
OFF2 (NONE, OFF1)
Acknowledge:
IMMEDIATELY
Cause:
When configuring the rotating measurement (p1959), no function was selected.
Remedy:
Select at least one function for automatic optimization of the speed controller (p1959).
