I have a RNR Control board with a HY 1.5 VFD . Im running a relay from my control board to a relay to the VFD. Im pretty sure the wiring is correct not so sure if mach3 is correct, Problem : when I hit my MPG or try to use Mach 3 to start and stop my spindlel nothing happens. the jumper is switched over to VI from the VR position to give control to a external control. I have looked over the wiring I can't tell you how many times and it is correct. When the jumper in on the VR position I can control the on /off and speed by the potentiometer on the VFD. When the jumper is switched back to VI, the mach3 spindle light just blinks yellow.. I can get the relay to change when I put in the M3 and M4 codes. M5 cancels the codes like it is suppose to. Question how do I activate the spindle using my external device.

PSS I have my VFD set the following settings:

Pd005=400hz
Pd004=400
Pd003=400
Pd072=400
Pd144=3000
Pd141=110 v
Pd142=4 amps
Pd143=2

Any ideas
