Finished Plugins for Download / Re: Huanyang VFD controller plugin
« on: November 14, 2016, 09:42:09 PM »
Hi All
I have the Huanyang VFD and spindle which works fine manually. I set up and followed the Royaumedeole method of connecting the VFD to Mach3 (is this the best way to go??). I triple checked all connections and ohm checked for shorts and polarity as well. The USB to RS485 converter is the one shown on the Royaumedeole instructions.
The problem is that when I turned the power on to the VFD (with the USB converter plugged IN to my PC) there was a slight pop from the VFD and all my power went off due to a trip of the houses earth leakage circuit breaker? Both the VFD and the USB converter are now U/S
There is a label on the front of the VFD that says 'CAUTION - confirm that output or control wires are not grounded'. I am aware that a USB port case is grounded as is one of the pins. I had checked that there were no shorts to earth before powering up. Funny thing is that if I plug the USB lead into the PC (with a new USB converter) while the VFD is powered on there is no problem. I again tried to power the VFD on WITH the USB connected to the PC and the lights went off again. Another fried USB converter!! There doesn't appear to be any shorts in the VFD on the power in or out or between them and the control terminals.
I have now purchased a new VFD and USB converter but am most reluctant to try again. I would appreciate any advice or suggestions.
