Description
Standstill ID run. The motor is injected with DC current.
With an AC induction (asynchronous) motor, the motor
shaft is not rotated. With a permanent magnet motor
or synchronous reluctance motor, the shaft can rotate
up to half a revolution.
Note: A standstill ID run should be selected only if the
Normal, Reduced or Advanced
because of the restrictions caused by the connected
mechanics (e.g. with lift or crane applications.
See also selection Advanced
The autophasing routine determines the start angle of
a permanent magnet or synchronous reluctance motor
(see section Autophasing (page
not update the other motor model values.
Autophasing is automatically performed as part of the
Normal, Reduced, Standstill,
Standstill ID runs. Using this setting, it is possible to
perform autophasing alone. This is useful after changes
in the feedback configuration, such as the replacement
or addition of an absolute encoder, resolver, or pulse
encoder with commutation signals.
Note: This setting can only be used after a Normal,
Reduced, Standstill, Advanced
ID run has already been performed.
Note: Depending on the selected autophasing mode,
the shaft can rotate during autophasing. See parameter
21.13 Autophasing mode.
Requests current measurement calibration, i.e.
identification of current measurement offset and gain
errors.
The calibration will be performed at next start.
