Tips: Can a VFD run on 400Hz?
Variable frequency drive (VFD) running on 400 Hz is not a problem as most VFDs can provide that output frequency but some may require a firmware modification to go that high. That high of an output frequency would also require a carrier frequency of at least 4 to 4.8 kHz as the ratio is required to be at least 1 to 10 but 1 to 12 is better. With that being said, the higher carrier frequency would require most VFDs to be derated a little bit.
