Switching frequency
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.

Slip compensation
Slip compensation for V/f characteristic control and sensorless vector control
• A higher slip compensation results in a higher increase in frequency and voltage when the machine is under load.
• After the motor to be used has been selected from the »Engineer« motor catalogue, the suitable value can be
entered automatically. An automatic detection via the motor parameter identification is possible as well.

Auto-DCB: Threshold
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.
