P2-24 PWM switching frequency

Setting range: 2 to 16 kHz (power-dependent)

Specifies the pulse width modulated switching frequency. A higher switching frequency means less motor noise, but also higher losses in the output stage. The maximum switching frequency depends on the inverter power rating.

The inverter reduces the switching frequency automatically when the heat sink temperature is excessively high. This automatic protection function can be deactivated with P6-02.
