Example
In this example, a 400 V/50 Hz motor is connected to the inverter which is to be operated
with maximally 75 Hz. The minimum frequency is set to 10 Hz.
• V/f characteristic on the left: The inverter is operated with a rated mains voltage of
400 V.
• V/f characteristic on the right: The inverter is operated with a rated mains voltage of
480 V. This causes the output voltage to further increase above 50 Hz.
