Hello!
I have a CNC router that I bought second hand some years ago. Now I'm updating my motion controller to a new one (C94 from cnc4pc) and switching from mach3 to uccnc. Old wiring was done by the previous owner and the spindle was controlled with the VFD:s own buttons and works fine and I didn't even try to get it to work through Mach.
The spindle is some Chinese 2.2kw water cooled 24k rpm and the VFD:s label says CT200-2D2G-2. Grid is 230v. Old card was Bsmce04u-plus
Now I would like to control the spindle with uccnc so I need to wire the VFD to the C94. The problem is that the markings on the VFD:s connection pins don't seem to resemble anything that I could find online nor do I have a manual for the VFD and can't seem to find one that has the same markings as the VFD:s connection pins. Pic of the pins and their labels attached.
So I'm pretty lost about what pin is what and I don't know how to figure them out so any help would be appreciated!
Fwd, Rev and Com are pretty self explanatory.
RA and RB are probably relay related but then I get confused when there is more than one of them as with the other connections too.
Previous owner couldn't get the mach3 spindle controls to work so I'm not even sure the previous wirings were right. They were:
From VFD -> to Motioncard
X4 -> AVI+
RA -> AVI-
FWD -> OUT2
RA -> IN1
RB -> COM-
And a jumper from vfd RA to vfd COM as seen in the picture. There were also wires from VFD RA and RB to a mpg outlet.
Maybe the VFD setting are wrong too since it didn't work but first I would like to get the wiring right before jumping into those.
And sorry if this is a dumb question or my explanations are confusing/lack information, it's my first time with CNC wiring
