5.4.4 Identifying the motor data and optimizing the closed-loop control
Overview
Using the motor data identification, the inverter measures the data of the stationary motor. In
addition, based on the response of the rotating motor, the inverter can determine a suitable
setting for the vector control.
To start the motor data identification routine, you must switch-on the motor via the terminal
strip, fieldbus or from the operator panel.
Identifying the motor data and optimizing the closed-loop control
Preconditions
● You have selected a method of motor data identification during quick commissioning, e.g.
measuring motor data while the motor is stationary.
When quick commissioning is complete, the inverter issues alarm A07991.
● The motor has cooled down to the ambient temperature.
An excessively high motor temperature falsifies the motor data identification results.
WARNING
Unexpected machine motion while the motor data identification is in progress
For the stationary measurement, the motor can make several rotations. The rotating
measurement accelerates the motor up to the rated speed. Secure dangerous machine parts
before starting motor data identification:
● Before switching on, ensure that nobody is working on the machine or located within its
working area.
● Secure the machine's work area against unintended access.
● Lower suspended loads to the floor.
Procedure
Press the HAND/AUTO key.
The BOP-2 displays the symbol indicating manual operation.
Switch on the motor.
During motor data identification, "MOT-ID" flashes on the BOP‑2.
If the inverter again outputs alarm A07991, then it waits for a new ON command to start the
rotating measurement.
