P862/P863 PWM fix 1/2

On (no automatic change of the clock frequency by the inverter)

Off (autonomous change of the clock frequency by the inverter depending on the utilization)

The inverter automatically switches back to lower switching frequencies when the unit utilization reaches a specific level if the clock frequency for parameter set 1/2 is not fixed to the set value using P862/P863 PWM fixed 1/2. The modulation frequency reduces switching losses in the output stage and, consequently, unit utilization.

If the clock frequency is set to a fixed value, please note the maximum permitted nominal output current for higher clock frequencies. Observe chapter "Overload capacity".
