Reduced
Reduced ID run. This mode should be selected instead of the Normal
ID run
• if mechanical losses are higher than 20% (ie, the motor cannot be
de-coupled from the driven equipment), or
• if flux reduction is not allowed while the motor is running (ie, in case
of a motor with an integrated brake supplied from the motor
terminals), or
• if large speed vibrations are detected during the Normal ID run.
With Reduced ID run, the control in the field weakening area or at high
torques is not necessarily as accurate as with the Normal ID run.
Reduced ID run is completed faster than the Normal ID run (< 90
seconds).
Note:
Check the direction of rotation of the motor before starting the
motor ID run. During the run, the motor will rotate in the forward
direction.
WARNING!
The motor will run at up to approximately
50…100% of the nominal speed during the motor ID run.
ENSURE THAT IT IS SAFE TO RUN THE MOTOR BEFORE
PERFORMING THE MOTOR ID RUN!
(3)
Standstill
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 (eg, with lift or crane applications).
(4)
Autophasing
During autophasing, the start angle of the motor is determined. Note
that other motor model values are not updated. See also parameter
.
Notes:
• Autophasing can only be selected after the Normal/Reduced/
Standstill ID run has been performed once. Autophasing is used
when an absolute encoder, a resolver or an encoder with
commutation signals 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%.
(5)
Cur meas cal
Current offset and gain measurement calibration. The calibration will
be performed at next start.
