Description / Notes
•
Pulse frequency 0 - 7
[rating
dependent]
[0]
Sets the pulse frequency (from 2 to 16 kHz)
and the PWM mode. If silent operation is not
absolutely necessary, the losses in the inverter
as well as the RFI emissions can be reduced
by selecting lower pulse frequencies.
0/1 = 16 kHz (230 V default)
2/3 = 8 kHz
4/5 = 4 kHz (400 V default)
6/7 = 2 kHz
Even numbers = normal modulation technique.
Odd numbers = lower loss modulation
technique used when operating mainly at
speeds above 5 Hz. (Not generally for fan
and pump applications)
Due to higher switching losses at increased frequencies, certain inverters may have their maximum
continuous current (100%) derated if the switching frequency is changed from the default value.
