3.8.5 Saving parameter settings safe against mains failure
The parameter set must be saved to the device safe against mains failure to prevent parameter
settings becoming lost due to mains switching.
Save parameter set.
3.8.6 Enable controller and test application
If the controller is in the " SwitchedOn " status:
1. Enable controller: Set terminal X4/RFR to HIGH level or close contact.
• If there is no other active source for the controller inhibit, the controller changes from the
" SwitchedOn " status to the " OperationEnabled " status.
• The Diagnostics tab and C00158 display all active sources for the controller inhibit.
2. Select the respective control signals via the digital inputs.

Note!
If the controller is enabled and the "Inhibit at power-on" auto-start option is activated in
C00142 (Lenze setting) when the mains is connected, the controller remains in the
" ReadyToSwitchOn " state.
To be able to change to the " SwitchedOn " status, the controller enable must be
deactivated first: set terminal X4/RFR to LOW level.
