Description
Defines the nominal motor power. Must equal the value on
the motor rating plate.
Power
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.
The Motor ID run process is not run. Identification
magnetization is performed, depending on parameter
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
TORQ): Identification magnetization is performed.
• Parameter 9904 = 3
magnetization is not performed.
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
[VECTOR: SPEED] or 2
• 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!
