    I’m trying to understand can a rheostat be used to control the speed output of a VFD. We have the VFD up and running but the client is not comfortable with adjusting the fans speed thru the face plates up and down menu. I swear I saw the term rheostat on the YASKAWA site somewhere. Then my crazy brain started wondering why a standard rotary style lighting dimmer could not be used. its a rheostat is it not? and to get to my bigger question, if not can someone please tell me the part number of a variable control I can connect to the YASKAWA V1000.

    To answer your question, Lighting Dimmers are actually not just a rheostat. They will usually consist of a pot connected to a Triac firing circuit to control the voltage output to your lamps being dimmed. Definitely will not work on the speed command input of the V1000, ok?

    Edmund, I just got a link from 1 of our product managers for you; http://www.galco.com/shop/Potentiometer-Operators-Potentiometers this will give lots of options for speed pots with or without knobs, single turn and multi turn as well.
