Check that the load torque is not too
high for the Turning mode (must be
less than 5%).
Check that the motor is not already
rotating when the autophasing routine
starts.
Motor is rotating during autophasing.0002
Check that encoder is not slipping.Too much difference between
measured and estimated positions.
0003
Check parameter 98.15 several times
to verify that the autophasing routine
gives consistent results.
Check the motor model parameters.
Check that the zero pulses are given
correctly.
Rotor did not rotate as expected
between zero pulses.
0004
Check that the selected mode
(parameter 21.13) is appropriate for
the motor.
Position estimate did not stabilize.0005
