Interfacing Bob Campbell's Breakout Board and a HuanYang VFD inverter
In order to upgrade my machine to a HuanYang VFD 2.2Kw water cooled spindle, I need to interface the Inverter to an existing Bob Campbell Combo Breakout board! This board has a built in Spindle interface, but I have no idea how to connect the pins to the inverter!
Inverter connections:
V1
DCM
ACM
FOR
REV
Breakout Board Pins:
1 - +18 dc unregulated
2 - buffered out1 step
3 - buffered out2 direction
4 - PC Gnd
5 - +12v isolated from PC
6 - Gnd isolated from PC
I have sent email's to Bob Campbell, but he was no help!

It's not what you take away, it's what you are left with that counts!
