Autotune Failed
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.
-
41
Measured motor stator resistance 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.
-
42
Measured motor inductance is too low. Ensure the motor is correctly connected and free from
faults.
-
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.
-
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 connected drive.
