Restoring the factory setting
There are cases where something goes wrong when commissioning a drive system e.g.:
● The line voltage was interrupted during commissioning and you were not able to complete
commissioning.
● You got confused during the commissioning and you can no longer understand the
individual settings that you made.
● You do not know whether the inverter was already operational.
In cases such as these, reset the inverter to the factory setting.
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.
The settings of the safety functions are protected by a password.
Settings that are not changed when restoring the factory setting
The communication settings and the settings of the motor standard (IEC/NEMA) are kept
when restoring the factory setting.
