Identify motor data
Danger to life from machine movements while motor data identification is in progress
The stationary measurement can turn the motor a number of revolutions. 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 working area against unintended access.
• Lower suspended loads to the floor.
Preconditions
● You selected a method of motor data identification during basic commissioning, e.g.
measurement of the motor data while the motor is stationary.
When basic commissioning is complete, the inverter issues alarm A07991.
● The motor has cooled down to the ambient temperature.
An excessively high motor temperature distorts the results of motor data identification.
Procedure with STARTER
To initiate motor data identification and optimize the motor control, proceed as follows:
1. Open the control panel.
