Preconditions
● You 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.
Procedure when using the BOP-2 operator panel
To start the motor data identification, proceed as follows:
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.
If the inverter does not output alarm A07991, switch off the motor as described below, and
switch over the inverter control from HAND to AUTO.
Switch on the motor to start the rotating measurement.
During motor data identification, "MOT-ID" flashes on the BOP-2.
The motor data identification can take up to 2 minutes depending on the rated motor power.
Depending on the setting, after motor data identification has been completed, the inverter
switches off the motor - or it accelerates it to the setpoint.
If required, switch off the motor.
Switch the inverter control from HAND to AUTO.
You have completed the motor data identification.
