4.2 List of faults and alarms
A07975 (N) Drive: Travel to the zero mark - setpoint input expected
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: NONE
Acknowledge: NONE
Cause: The zero mark must be evaluated in order to adjust the encoder.
It is expected that a speed or torque setpoint is entered.
Remedy: Not necessary.
The alarm disappears once the zero mark has been detected.
A07980 Drive: Rotating measurement activated
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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
Message class: Error in the parameterization / configuration / commissioning procedure (18)
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.

F07982 Drive: Rotating measurement encoder test
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Reaction: OFF1 (NONE, OFF2)
Acknowledge: IMMEDIATELY
Cause: A fault has occurred during the encoder test.
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.
5: The encoder does not supply a signal.
6: Incorrect polarity.
7: Incorrect pulse number.
8: Noise in the encoder signal or speed controller unstable.
Remedy: For fault value = 1:
- check the motor parameters.
- carry out a motor data identification routine (p1900 = 2).
- possibly reduce the dynamic factor (p1967).
For fault value = 2:
- adapt the speed setpoint (p1965) or adapt the minimum limit (p1080).
