For fault value = 2:
Bring the motor into a no-load condition.
For fault value = 10:
When selecting p1980 = 4: Increase the value for p0325.
When selecting p1980 = 1: Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the power unit involved.
For fault value = 11:
Increase the value for p0329.
Check whether the motor is correctly connected.
Replace the power unit involved.
For fault value = 12:
When selecting p1980 = 4: Reduce the value for p0325.
When selecting p1980 = 1: Reduce the value for p0329.
Check whether motor data have been correctly entered.
For fault value = 13:
Reduce the value for p0329.
Check whether motor data have been correctly entered.
For fault value = 14:
Increase the value for p0329.
For fault value = 15:
Increase the value for p0325.
Motor not sufficiently anisotropic, change the technique (p1980 = 1 or 10).
For fault value = 16:
Change the technique (p1980).
For fault value = 17:
Repeat technique.
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).
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.
