h
Boost of the V/f voltage characteristic in the range of small speeds or frequencies with V/f characteristic control
( VFCplus ) and V/f control ( VFCplus+encoder )
• This may increase the starting torque.
• After the motor to be used has been selected from the motor catalogue, the suitable value can be entered
automatically. An automatic detection via the motor parameter identification is possible as well.

Selection of the pulse width modulated switching frequency transferred from the inverter to the motor
• Select between an ideal setting for the drive which provides smooth running, and an optimal setting with regard
to the inverter which keeps its losses to a minimum (min. Pv).
• Both possibilities offer fixed and variable switching frequencies.
• When a variable switching frequency is selected, the switching frequency may change as a function of the load
and rotational frequency.
