5.3 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 your inverter is using safety functions, e.g. "Safe Torque Off" or "Safely Limited Speed",
then you must first always reset the safety functions.
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.
Resetting the safety functions to the factory settings
If the safety functions are enabled in your inverter, then the safety function settings are
password-protected. You must know the password to reset the safety function settings.
Procedure
Proceed as follows to restore the inverter safety functions to the factory settings:
1. Go online
2. Call the safety functions screen form
3. In the "Safety Integrated" screen form, press the button for restoring the factory setting.
4. Enter the correct password.
5. Switch off the inverter supply voltage.
6. Wait until all LEDs on the inverter go dark.
7. Switch on the inverter supply voltage again.
You have restored the safety function settings of your inverter to the factory settings.
