Parameters 295
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!
1
Reduced
Reduced ID run. This mode should be selected instead of
the
or
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).
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!
2
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
ID run is not possible due to the
restrictions caused by the connected mechanics (e.g. with
lift or crane applications).
