Warnings, faults and system messages
9.6 List of fault codes and alarm codes
A07980
Drive: Rotating measurement activated
Reaction:
NONE
Acknowledge:
NONE
Cause:
The rotating measurement (automatic speed controller optimization) is activated.
The rotating measurement is carried out at the next switch-on command.
Note:
During the rotating measurement it is not possible to save the parameters (p0971).
See also: p1960 (Rotating measurement selection)
Remedy:
Not necessary.
The alarm disappears automatically after the speed controller optimization has been successfully completed or for the
setting p1900 = 0.
A07981
Drive: Enable signals for the rotating measurement missing
Reaction:
NONE
Acknowledge:
NONE
Cause:
The rotating measurement cannot be started due to missing enable signals.
For p1959.13 = 1, the following applies:
- enable signals for the ramp-function generator missing (see p1140 ... p1142).
- enable signals for the speed controller integrator missing (see p1476, p1477).
Remedy:
- acknowledge faults that are present.
- establish missing enable signals.

F07983
Drive: Rotating measurement saturation characteristic
Reaction:
OFF1 (NONE, OFF2)
Acknowledge:
IMMEDIATELY
Cause:
A fault has occurred while determining the saturation characteristic.
Fault value (r0949, interpret decimal):
1: The speed did not reach a steady-state condition.
2: The rotor flux did not reach a steady-state condition.
3: The adaptation circuit did not reach a steady-state condition.
4: The adaptation circuit was not enabled.
5: Field weakening active.
6: The speed setpoint was not able to be approached as the minimum limiting is active.
7: The speed setpoint was not able to be approached as the suppression (skip) bandwidth is active.
8: The speed setpoint was not able to be approached as the maximum limiting is active.
9: Several values of the determined saturation characteristic are not plausible.
10: Saturation characteristic could not be sensibly determined because load torque too high.
