I just bought a new Huanyang HY02D2 to replace the old Fuling. I'm trying to wire it the same as the Fuling but the labels on the control circuit terminals are totally different. I got the power in and out to the spindle figured out, but the old Fuling had 2 wires (red & white) going to S1 and DCM terminals. The terminals on the new Huanyang are: FA FC FB 24V DCM -- 5V ACM AI VI RS- RS+

Fuling: S1 S2 DCM S3 S4 S5 S6 DCM EV -- SG+ SG-

Anybody know how these are wired? I don't even know what those 2 wires go to, I just want it connected the same as it was to the old one.

Thanks
