9910 ID RUN 0, 1 1 0 (OFF/IDMAGN)
This parameter controls a self-calibration process called the Motor ID Run. During this process, the drive operates
the motor (motor rotating) and makes measurements in order to identify motor characteristics and create a model
used for internal calculations. An ID Run is especially effective when:
• vector control mode is used [parameter 9904 = 1 (VECTOR:SPEED) or 2 (VECTOR:TORQ)], and/or
• 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 (i.e. without a pulse encoder).
0 = OFF/IDMAGN – The Motor ID Run process is not run. Identification magnetization is performed, depending on
parameter 9904 and 2101 settings. 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). 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) and parameter 2101 = 3 (SCALAR FLYST) or 5 (FLY + BOOST): Identification
magnetization is performed.
• Parameter 9904 = 3 (SCALAR:FREQ) and parameter 2101 has other value than 3 (SCALAR FLYST) or 5 (FLY +
BOOST): Identification magnetization is not performed.
1 = ON – Enables the Motor ID Run, during which the motor is rotating, at the next start command. After run
completion, this value automatically changes to 0.
Note: The motor must be de-coupled from the driven equipment.
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.
The motor will rotate in the forward direction.
Ensure that it is safe to run the motor before performing the ID Run!
9915 MOTOR COSPHI 0.01…0.97 0.01 0 (IDENTIFIED)
Defines the nominal motor cos phi (power factor). The parameter improves performance especially with high
efficiency motors.
0 = IDENTIFIED – Drive identifies the cos phi automatically by estimation.
0.01…0.97 – Value entered used as the cos phi.
