3.4.4 Save parameter settings safe against mains failure
In order that parameter settings made in the device do not get lost by means of mains switching,
you must safe the parameter set explicitly safe against mains failure in the device.
• Save parameter set
3.4.5 Enable controller and select speed
When the controller is in the "SwitchedON" state:
1. Enable controller:
Set terminal X4/RFR to HIGH level or close contact to terminal X4/12I n.
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.
 Tip!
More control functions in the "Terminals 0" control mode:
• DI3: HIGH level ≡ request DC-injection braking
• DI4: HIGH level ≡ request change of direction of rotation
 Note!
If the controller is enabled at power-on and the auto-start option is activated in C142
(Lenze setting), the controller remains in the "ReadyToSwitchON
" state (display in C137).
For changing to the "SwitchedON
" state, first deactivate the controller enable: Set termi-
nal X4/RFR to LOW level or open contact to terminal X4/12I.
DI1 DI2 Speed selection
LOW LOW The setpoint speed is selected via the analog input 1
• Scaling: 10 V ≡ 100 % ≡ reference speed (C011
)
HIGH LOW The fixed setpoint 1 (C039/1
) is used as setpoint speed.
• Lenze setting: 40 % of the reference speed (C011
)
LOW HIGH The fixed setpoint 2 (C039/2
) is used as setpoint speed.
• Lenze setting: 60 % of the reference speed (C011
)
HIGH HIGH The fixed setpoint 3 (C039/3
) is used as setpoint speed.
• Lenze setting: 80 % of the reference speed (C011
)
 Note!
Observe the actual speed value (display in C051) as well as the LED status display and
Display messages
indicated in the keypad.
