I happen to come across a guy selling a water cooled 2.2kw spindle setup that he just removed from an Avid machine due to an upgrade. Long story short, the price was right and I made the purchase. The spindle is a GMT and the VFD is a Delta VFD022M21A. The wiring (power and motor) are pretty straight forward. However, I am having trouble understanding the wiring between the vfd and my controller so I can control things through Mach3. I thought it would be pretty easy using the VFD schematic and MX4660 setup guide from Avid but I guess I was wrong. For one - the VFD schematic shows 6 wires while the controller guide shows 5. Also, I figured the wire colors would match but began to question myself on that assumption. What I am looking for is some help to cross reference the controller connections to those on the VFD.
MX4660 EGND ------> VFD XXXXX
MX4660 0-10V Out ------> VFD YYYYY
MX4660 +10Vdc In ------> VFD ZZZZZ
MX4660 Output 1- ------> VFD AAAAA
MX4660 Output 1+ ------> VFD BBBBB
What I need is help with is identifying XXXXX, YYYYYY, ZZZZZ, AAAAA and BBBBB
I've included snapshots of the relevant info from the Avid Guides and the Delta VFD manual
Thanks for your help!!
Dan
