What sort of waveform should i expect to see on the output side of a 1336+2 VFD. We don't have a functional o'scope in the shop right now, and therefore the debate rages. Thanks

sawtooth

Generalized that is, the output of a VFD is pulsating DC but since it creates a waveform it can be read as AC

Just cuz I had the time...

The saw-tooth pattern is produced via Pulse Width Modulation.
