74 Fault tracing
AtF-01
40
Autotune Fault
Measured motor stator resistance varies between
phases. Ensure the motor is correctly connected and
free from faults. Check the windings for correct
resistance and balance.
AtF-02
41
Measured motor stator resistance too large. Ensure
motor is correctly connected and free from faults.
Check that the power rating corresponds to the
power rating of the connected drive.
AtF-03
42
Measured motor inductance too low. Ensure the
motor is correctly connected & free of faults.
AtF-04
43
Measured motor inductance is too large. Ensure the
motor is correctly connected and free from faults.
Check that the power rating corresponds to the
power rating of the connected drive.
AtF-05
44
Measured motor parameters are not convergent.
Ensure the motor is correctly connected and free
from faults. Check that the power rating corresponds
to the power rating of the drive.
