5.5 Restoring the factory setting
5.5.1 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.
Procedure with an operator panel
Proceed as follows to restore the inverter safety functions to the factory settings:
1. p0010 = 30Set
Activate reset settings.
2. p9761 = ...
Enter the password for the safety functions
3. Start the reset with p0970 = 5.
4. Wait until the inverter sets p0970 = 0.
5. Set p0971 = 1.
6. Wait until the inverter sets p0971 = 0.
7. Switch off the inverter supply voltage.
8. Wait until all LEDs on the inverter go dark.
9. Switch on the inverter supply voltage again.
You have restored the safety function settings of your inverter to the factory settings.
