Description
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 ID run. This mode should be selected instead of the
Normal or Advanced ID Run if
• mechanical losses are higher than 20% (i.e. the motor
cannot be de-coupled from the driven equipment), or if
• flux reduction is not allowed while the motor is running (i.e.
in case of a motor with an integrated brake supplied from
the motor terminals).
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!
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 or synchronous
reluctance motor, the shaft can rotate up to half a revolution.
Note: A standstill ID run should be selected only if the
Normal, Reduced or Advanced
