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
1. Enable controller
• 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:

Tip!
Other control functions in the "Terminal 0" control mode:
• DI3: HIGH level ≡ Request DC-injection braking
• DI4: HIGH level ≡ Request a change of direction of rotation

brake on the motor shaft has been released!
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 )
