Is it possible to somehow wire this spindle inverter up to Mach3?
Currently I need to turn on the spindle by pressing the blue button on the inverter then press cycle start, I'd like to use Mach to start the spindle, control the rpm and stop the spindle.....is it possible?
Easy, find the manual for it. See how to program the I/O lines to do what you want and wala. The I/O lines usually take 0-10 volts and 4-20 mA. Or put up manual i'll look at it. You can make it control the speed also.
Does it only have the Network plug in it?
Most vfd's i've seen also have i/o lines
