Autotune fail 1
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.
tF-
41
Autotune fail 2
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.
tF-

Autotune fail 3
Measured motor inductance is too low. Ensure the motor is correctly
connected and free from faults.
tF-
43
Autotune fail 4
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.
tF-
44
Autotune fail 5
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.
