What to do
Try other autophasing modes (see
parameter 21.13 Autophasing
possible.
If the Turning with Z-pulse
selected, check the zero pulse given by
the encoder.
Check that the motor ID run has been
successfully completed.
Clear parameter 98.15 Position offset
user.
Check that the encoder is not slipping on
the motor shaft.
Check that the motor is not already
turning when the autophasing routine
starts.
Check the setting of parameter
Motor type.
Check the settings of parameters
and 35.62.
Check the dimensioning of the motor
cable in regard to required load.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware manual.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
