296 Parameters
Reduced
Reduced ID run. This mode should be selected instead of the
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).
3
Reserved
4…5
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!
