Normal Normal ID run. Guarantees good control accuracy
for all cases. The ID run takes about 90 seconds.
This mode should be selected whenever it is
possible.
Notes :
• If the load torque will be 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 Normal ID run.
• 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. ENSURE THAT IT IS SAFE
TO RUN THE MOTOR BEFORE PERFORMING THE
ID RUN!

Reduced Reduced ID run. This mode should be selected
instead of the
Normal
or
Advanced
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
With this ID run mode, the resultant motor
control in the field weakening area or at high
torques is not necessarily as accurate as motor
control following a 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 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. ENSURE THAT IT IS SAFE
TO RUN THE MOTOR BEFORE PERFORMING THE
ID RUN!
