Description
The autophasing routine determines the start angle of a
permanent magnet or synchronous reluctance motor (see
page 96). Autophasing does 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.
Notes:
• This setting can only be used after a Normal, Reduced,
Standstill, Advanced
already been performed.
• Depending on the selected autophasing mode, the shaft
can rotate during autophasing. See parameter
Autophasing mode.
Requests current measurement calibration, ie. identification
of current measurement offset and gain errors.
The calibration will be performed at next start.
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!
This selection is recommended with AC induction motors up
to 75 kW instead of the
• the exact nominal ratings of the motor are not known, or
• the control performance of the motor is not satisfactory
after a Standstill ID run.
Note: The time it takes for the
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.
