SINAMICS S List Manual (LH1), 07/2007
Remedy: Re 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 %).
Re fault value = 2:
- adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
Re fault value = 3:
- adapt the speed setpoint (p1965) or suppression (skip) bandwidths (p1091 ... p1094, p1101).
Re fault value = 4:
- adapt the speed setpoint (p1965) or maximum limit (p1082, p1083 and p1086).
Re fault value = 5:
- increase the torque limits (e.g. p1520, p1521).
Re 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
Drive object: VECTOR
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 direction of rotation is inhibited.
Remedy: Re fault value = 1:
Enable the direction of rotation (p1110 or p1111).
A07987 Drive: Rotating measurement, no encoder available
Drive object: VECTOR
Reaction: NONE
Acknowledge: NONE
Cause: No encoder available. The rotating measurement was carried out without encoder (sensorless).
Alarm value (r2124, interpret decimal):
1: An encoder is not connected.
2: It involves a SINAMICS G drive unit that only supports sensorless closed-loop control.
Remedy: Re alarm value = 1:
Connect-up the encoder.
Re alarm value = 2:
None necessary.
F07988 Drive: Rotating measurement, no configuration selected
Drive object: VECTOR
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).

F07989 Drive: Rotating measurement leakage inductance (q-axis)
Drive object: VECTOR
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: An error has occurred while measuring the dynamic leakage inductance.
Fault value (r0949, interpret 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.
