4.
Switch on the motor.
The inverter starts the motor data identification. This measurement can take several
minutes.
Depending on the setting, after motor data identification has been completed, the inverter
switches off the motor - or it accelerates it to the currently set setpoint.
5.
If required, switch off the motor.
6.
Relinquish the master control after the motor data identification.
7.
Save the settings in the inverter (RAM → EEPROM):
You have completed the motor data identification.
❒
Self-optimization of the speed control
If you have not only selected motor data identification with the motor stationary, but also
rotating measurement with self-optimization of the speed control, you must switch on the
motor again as described above and wait for the optimization run to finish.
Quick commissioning has been completed once the motor data identification has been
successfully completed.

Restoring the factory setting
5.6.1
Restoring the factory setting
When must you reset the inverter to the factory settings?
Reset the inverter to the factory settings in the following cases:
●
The line voltage was interrupted during commissioning and you were not able to complete
commissioning.
●
You can no longer trace the settings that you made during commissioning.
●
You do not know whether the inverter was already operational.
Restoring the factory settings when the safety functions are enabled
If you are using the integrated safety functions of the inverter, e.g. "Safe Torque Off", you
must reset the safety functions separately from the remaining inverter settings.
