Description
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: If the load torque is higher than 20% of motor
nominal torque, or if the machinery is not able to
withstand the nominal torque transient during the ID
run, then the driven machinery must be de-coupled
from the motor during a Advanced ID run.
Note: Check the direction of rotation of the motor
before starting the 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 ID run. Several accelerations and
decelerations are done. MAKE SURE THAT IT IS

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.
