Parameters and firmware blocks
Standstill ID run. The motor is injected with DC current. With
asynchronous motor, the motor shaft is not rotating (with permanent
magnet motor the shaft can rotate < 0.5 revolution).
Note: This mode should be selected only if the Normal or Reduced ID
run is not possible due to the restrictions caused by the connected
mechanics (e.g. with lift or crane applications).
During autophasing, the start angle of the motor is determined. Note
that other motor model values are not updated. See also parameter
11.07 AUTOPHASING MODE, and section
Notes:
• Autophasing can only be selected after the Normal/Reduced/
Standstill ID run has been performed once. Autophasing is used
when an absolute encoder has been added/changed to
a permanent magnet motor and there is no need to perform the
Normal/Reduced/Standstill ID run again.
• During Autophasing the motor shaft must NOT be locked and the
load torque must be < 5%.
Current offset and gain measurement calibration. The calibration will
be performed at next start.
