3.7.5 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.
3.7.6 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 speed setpoint.
In the "Terminal 0" control mode by selecting a voltage at the analog input via the setpoint
potentiometer or by selecting a fixed setpoint via the digital DI1/DI2 inputs:

Stop!
Before stipulating a speed setpoint, check whether the brake in the form of a holding
brake on the motor shaft has been released!

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.
DI1 DI2 Speed selection
LOW LOW The setpoint speed is selected via analog input 1
• Scaling: 10 V ≡ 100 % ≡ reference speed ( C00011 )
HIGH LOW Fixed setpoint 1 ( C00039/1 ) is used as setpoint speed.
• Lenze setting: 40 % of the reference speed ( C00011 )
LOW HIGH Fixed setpoint 2 ( C00039/2 ) is used as setpoint speed.
• Lenze setting: 60 % of the reference speed ( C00011 )
HIGH HIGH Fixed setpoint 3 ( C00039/3 ) is used as setpoint speed.
• Lenze setting: 80 % of the reference speed ( C00011 )

Note!
Observe the actual speed value (display in C00051 ) as well as the LED status displays .
