5.12.3 Restoring safety-related parameters to the factory setting
Before starting to commission the safety functions, you should know whether the safety-
relevant parameters of the inverter have already been changed. If you do not precisely know
the setting of the safety-relevant parameters, then reset these parameters to the factory
setting.
Which parameters are reset to the factory setting?
Resetting the safety-relevant parameters to the factory setting does not change the setting of
the other parameters, e.g. the motor data or the significance of these terminals.
Restoring the factory setting sets all of the safety-relevant parameters back to their standard
values. Exceptions:
● P9761 SI password input
● P9762 SI password change
● P9763 SI confirmation of password change
Procedure
1. Connect the PC and the inverter using the PC connection kit or via the fieldbus
2. Go online by clicking on the button
and call the screen of the safety functions by
double clicking. The Safety Integrated menu is displayed in the main screen.
3. With the mouse, click on the button
at the lower edge of the screen.
4. Enter the safety password in the following screen and confirm with OK.
The safety-relevant parameters of the inverter have now been reset to the factory setting.
