C00018
Parameter | Name:
C00018 | 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.

C00019
Parameter | Name:
C00019 | 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.
