I'll try to keep it short.
Looking at upgrading the spindle to a 1.5kw servo motor to control in mach3.
Just need to know which inputs/outputs to use on the CN2 connection for: on/off, speed control, and if poss e-stop for if the spindle gets stuck so it stops Mach.
Shows that on the board:
The 2 connections for spindle on/off control goes top conn to FOR and bottom conn goes to DCM
The 2 for the 0-10V spindle speed output goes top to VI and bottom to ACM
Unsure if there is a stop circuit there.
Looks like the the speed/voltage regulation is + VREF & - AGND.
Looking at the diagram and vid with the VI and ACM inputs previously I assume the line that went to ACM input from the BOB is the negative? Correct?
Just need to know which to use for on/off and e-stop
