For fault value = 18:
Increase the value for p0329.
Saturation not sufficient, change the technique (p1980 = 10).
For fault value = 20:
Before carrying out a pole position identification routine ensure that the motor shaft is absolutely stationary (zero
speed).
A07975 (N) Drive: Travel to the zero mark - setpoint input expected
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.
A07976 Drive: Fine encoder calibration activated
Reaction: NONE
Acknowledge: NONE
Cause: The alarm indicates the phases of the fine encoder calibration using the alarm value.
Alarm value (interpret decimal):
1: Fine encoder calibration active.
2: Rotating measurement started (set the setpoint speed > 40 % rated motor speed).
3: Rotating measurement lies within the speed and torque range.
4: Rotating measurement successful: pulse inhibit can be initiated to accept the values.
5: Fine encoder calibration is calculated.
10: Speed too low, rotating measurement interrupted.
12: Torque too high, rotating measurement interrupted.
Remedy: Re alarm value = 10:
Increase the speed.
Re alarm value = 12:
Bring the drive into a no-load condition.
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 power-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.
