5.6 V/f control (VFCplus)
This function extension is available from software version V3.0!
If this motor control mode is set in C00006 , the output voltage of the controller follows a firmly
defined characteristic.
5.6.1 Basic settings
After the motor and controller have been optimally adjusted to each other, the "initial
commissioning steps" described in the following table are sufficient for a simple characteristic
control.
• Detailed information on the individual steps can be found in the following subchapters.

Tip!
How to optimise the control behaviour and adjust it to the concrete application is described
in the chapter " Optimising the control mode ". ( 188)
Parameterisable additional functions are described correspondingly in the chapter
" Parameterisable additional functions ". ( 200)

Note!
The operation of vertical drives/hoists is only supported up to 55 kW by the V/f control!
Initial commissioning steps
1. Defining the V/f characteristic . ( 182)
2. Setting the voltage boost . ( 183)
3. Parameterising load adjustment . ( 185)
4. Activating voltage vector control . ( 186)
• The Voltage Vector Control (VCC), which can be activated, serves to provide a torque at low field
frequencies. This task is executed by a current controller the output voltage of which is added to the
voltage from the characteristic.
5. Defining the current limit (Imax controller) . ( 187)
6. Additional "flying restart" function:
• In the Lenze setting, this parameterisable additional function is activated.
• If the flying restart function is not required, deactivate this function.  Flying restart function ( 209)

Only deactivate the flying restart if it is ensured that the drive is always at standstill in the case of controller
enable!
7. Additional "DC-injection braking" function:
• In the Lenze setting, this parameterisable additional function is deactivated.
• If DC-injection braking is required, activate this function.  DC-injection braking ( 212)
