3.7.5 Save parameter settings safe against mains failure
In order to prevent parameter settings carried out in the device from being lost by mains switching,
you have to explicitly save the parameter set with mains failure protection in the device.
Save parameter set.
3.7.6 Enable inverter and test application
If the inverter is in the "SwitchedOn" state:
1. Enable inverter: Set terminal X5/RFR to HIGH level or close contact.
• If there is no other active source for the controller inhibit, the inverter 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 at mains connection and C00142 has activated the "Inhibit at
power-on" auto-start option (Lenze setting), the inverter remains in the
"ReadyToSwitchOn
" state.
To be able to change to the "SwitchedOn
" status, the controller enable must be
deactivated first: set terminal X5/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.
