d
= 5FEF
h
Boost of the V/f voltage characteristic within the range of low speed or frequency values for the (
) V/f cha-
racteristic control.
• 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 auto-
matically. 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
• When a variable switching frequency is selected, the switching frequency may change as a function of the load
and rotational frequency.

h
Setpoint speed threshold for automatic DC injection braking
• For speed setpoints with values below the thresholds a DC current is injected or the motor is not supplied with
current, depending on the setting.
