Commissioning
5.4 Quick commissioning
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.
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.
Procedure
1. Open the control panel.
2. Assume master control for the converter.
3. Set the drive to enable state.
4. Switch on the motor.
The converter starts the motor data identification. This measurement can take several
minutes.
Depending on the setting, after motor data identification has been completed, the
converter switches off the motor - or it accelerates it to the currently set setpoint.
