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 quick commissioning, e.g.
measurement of the 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 distorts the results of motor data identification.
● The PC and inverter are connected to each other online.
Procedure with STARTER
To initiate motor data identification and optimize the motor control, proceed as follows:
1. Open the control panel.

2. Assume master control for the inverter.
3. Set the "Enable signals"
