Identifying motor data

Overview
Using the motor data identification, the converter measures the data of the stationary motor.
In addition, based on the response of the rotating motor, the converter can determine a
suitable setting for the vector control.
To start the motor data identification routine, you must switch on the motor.

Preconditions
• You have selected a method of motor data identification during quick commissioning, e.g.
measurement of the motor data while the motor is stationary.
When quick commissioning is complete, the converter issues alarm A07991.
• The motor has cooled down to the ambient temperature.
An excessively high motor temperature falsifies the motor data identification results.
• The PC and converter are connected to each other online.
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
• Secure the machine's work area against unintended access.
• Lower suspended loads to the floor.
