Parameters 311
Standstill 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, the
shaft can rotate up to half a revolution.
Note: This mode should be selected only if the Normal,
Reduced or Advanced ID run is not possible due to the
restrictions caused by the connected mechanics (e.g. with
lift or crane applications).
3
Advanced Advanced ID run. Guarantees the best possible control
accuracy. The ID run takes a very long time to complete.
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 may run at up to the
maximum (positive) and minimum (negative)
allowed speed during the ID run. Several
accelerations and decelerations are done. The maximum
torque, current and speed allowed by the limit parameters
may be utilized. ENSURE THAT IT IS SAFE TO RUN THE
MOTOR BEFORE PERFORMING THE ID RUN!

99.16 Motor phase order Switches the rotation direction of motor. This parameter
can be used if the motor turns in the wrong direction (for
example, because of the wrong phase order in the motor
cable), and correcting the cabling is considered
impractical.
Notes:
• Changing this parameter does not affect speed
reference polarities, so positive speed reference will
rotate the motor forward. The phase order selection just
ensures that “forward” is in fact the correct direction.
