huanyang vfd won't communicate get errors.

Shows the differences. Which is yours?

It's the real thing. I have had it form 6 or 7 years and there was no RS485 IC in it.. I don't know if the software to work with it is in this one. Maybe I'lll buy and new one. I can see hy_vfd putting data out but the vfd just doesn't answer.

Does anyone know the outside dimensions of the 2.2KW unit. I see no problem using a 2.2KW unit with a .8KW motor as long as the current parameter is set properly. Opinions welcomed.

No problem at all just set the max current.
I drive a 3KW motor with a 1.5 KW VFD from time to time without issues as it newer gets at full load, not even close.

Received the new 2.2 KW VFD. Installed it and it took right off. Everything is working but the speed produced by the spindle is off by about 20% across the range. How are your speeds? parameters are set for 400hz and 24000 rpm. I think I can probably increase the 2400 by 20% and fix the speed but I'm curious about others success.
