• The default setting does not need any changes in normal operation.
• Change the default setting in the following cases.
The wiring distance between the Inverter and motor is long:
Set the Inverter to a lower carrier frequency.
Reference carrier frequency: 10 kHz at a maximum wiring distance of 100 m and 5 kHz at a
Excessive speed or torque dispersion at low speed:
Set the carrier frequency to a lower value.
