Autophasing
The autophasing routine determines the start angle of a
permanent magnet or synchronous reluctance motor (see
page
). Autophasing does not update the other motor
model values.
Autophasing is automatically performed as part of the
,
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
or
ID run has
already been performed.
• Depending on the selected autophasing mode, the shaft
can rotate during autophasing. See parameter
.

Current
measurement
calibration
Requests current measurement calibration, ie.
identification of current measurement offset and gain
errors.
The calibration will be performed at next start.
5
Advanced
Advanced ID run. Guarantees the best possible control
accuracy. The ID run can take a couple of minutes. This
mode should be selected when top performance is needed
across the whole operating area.
Note: The driven machinery must be de-coupled from the
motor because of high torque and speed transients that
are applied.
WARNING!
The motor will run at up to
approximately 50…100% of the nominal speed
during the ID run. Several accelerations and
decelerations are done. ENSURE THAT IT IS SAFE TO
RUN THE MOTOR BEFORE PERFORMING THE ID
RUN!
6
Advanced Standstill
Advanced Standstill ID run.
This selection is recommended with AC induction motors
up to 75 kW instead of the
ID run if
• the exact nominal ratings of the motor are not known, or
• the control performance of the motor is not satisfactory
after a
ID run.
Note: The time it takes for the
ID run
to complete varies according to motor size. With a small
motor, the ID run typically completes within 5 minutes; with
a large motor, the ID run may take up to an hour.
