Hello,
Just putting this out there in case anybody needs it. This is compiled from info already available from other sites, i'm just cooking it down to make it work for the WD-1.
This is about how to enable the Mach3/WD-1 stock setup, turn on and off a Huanyang 2.2 VFD controlled spindle without any extra relays:
Disclaimer! Proceed at your own risk, your model may vary...
Change the VFD PD1 setting to 1 for external control. Disconnect and deactivate (remove or insulate) the two AC wires (Line and Load) going to the spindle control relay on the WD-1 control board, this is the relay used to switch the spindle outlet on and off. Attach two new insulated wires to those positions on the relay and route those to the VFD. Connect those wires to the positions marked DCM and FOR connections on the VFD upper rails - FOR for forward operation-REV for the other direction if needed. That's it, now when the software turns on the spindle on the WD (the outlet control) -the VFD controlled spindle turns on. As a test, do make sure it turns the right way as some people have their VFD set to REVERSE in the PD settings. If this is the case then just connect the wire to REV instead of FOR on the upper rails. This system works because all you have to do is SHORT the FOR (or REV) and DCM connections on the VFD to start the motor, this idea just uses the switching of the router control relay of the WD to accomplish the same thing. No extra relays needed, the only loss is the receptacle, but that could be wired to the other if needed, mind the current limitations though..In my case I was able to attach a decent size shop vac to the WD outlets now that the Router was taken care of separately.
