3.5.5 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.
• Saving parameter set
3.5.6 Enabling controller and selecting speed
If the controller is in the " SwitchedOn " status:
1. Enable controller: Set terminal RFR to HIGH level.
2. Select speed:
• In the "Terminals 0" by selecting a voltage at the analog input or by selecting a fixed setpoint
via the digital inputs DI1/DI2.

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.
In order to change to the " SwitchedOn " status, the controller enable must first be
cancelled: Set terminal RFR to LOW level.
DI1 DI2 Speed selection
LOW LOW The main speed setpoint is selected via the analog input 1
• Scaling: 10 V ≡ 100 % reference speed ( C00011 )
HIGH LOW The fixed setpoint 1 ( C00039/1 ) is used as main speed setpoint.
• Lenze setting: 40 % of the reference speed ( C00011 )
LOW HIGH The fixed setpoint 2 ( C00039/2 ) is used as main speed setpoint.
• Lenze setting: 60 % of the reference speed ( C00011 )
HIGH HIGH The fixed setpoint 3 ( C00039/3 ) is used as main speed setpoint.
• Lenze setting: 80 % of the reference speed ( C00011 )

Note!
Observe the actual speed value (display in C00051 ) and the LED status display at the
controller.
