Risk of injury or material damage as a result of machine movements when switching on the
motor
Switching on the motor for identification purposes may result in hazardous machine
movements.
Secure dangerous machine parts before starting motor data identification:
• Before switching on, check that no parts are loose on the machine or can be spun out.
• 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 hanging/suspended loads to the floor.
Procedure
To initiate motor data identification and optimization
of the motor control, proceed as follows:
1. Open by double-clicking on the control panel in
2. Assume master control for the inverter.
3. Set the "Enable signals"
4. Switch on the motor.
5. Relinquish the master control after the motor data
6. Click the
You have now completed motor data identification.
Self-optimization of the closed-loop control
If you have also selected a rotating measurement with self-optimization of the vector control
in addition to the motor data identification, then you must switch on the motor again as
described above and wait for the optimization run to be completed.
