9910 ID RUN
This parameter controls a self-calibration process called the
Motor ID run. During this process, the drive operates the
motor and makes measurements to identify motor
characteristics and create a model used for internal
calculations.

OFF/IDMAGN
The Motor ID run process is not run. Identification
magnetization is performed, depending on parameter
9904
MOTOR CTRL MODE . In identification magnetization, the
motor model is calculated at first start by magnetizing the
motor for 10 to 15 s at zero speed (motor not rotating,
except that a permanent magnet synchronous motor can
rotate a fraction of a revolution). The model is recalculated
always at start after motor parameter changes.
• Parameter
9904 = 1 ( VECTOR: SPEED ) or 2 ( VECTOR:
TORQ ): Identification magnetization is performed.
• Parameter 9904 = 3 ( SCALAR: FREQ ): Identification
magnetization is not performed.
0
ON ID run. Guarantees the best possible control accuracy. The
ID run takes about one minute. An ID run is especially
effective when:
• vector control mode is used (parameter
9904 = 1
[ VECTOR: SPEED ] or 2 [ VECTOR: TORQ ]), and
• operation point is near zero speed and/or
• operation requires a torque range above the motor
nominal torque, over a wide speed range, and without
any measured speed feedback (ie, without a pulse
encoder).
Note: The motor must be de-coupled from the driven
equipment.
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.
Note: If motor parameters are changed after ID run, repeat
the ID run.
WARNING! The motor will run at up to approximately
50…80% of the nominal speed during the ID run.
ENSURE THAT IT IS SAFE TO RUN THE MOTOR
BEFORE PERFORMING THE ID RUN!
