I need some help figuring out the proper pin and port settings for the VFD that controls the spindle on my mill.
the mill is a Hurco SM1 I am using the factory servos, Viper 200 amps, Smoothstepper, CNC4PC C23 BOB, Durapulse GS3 VFD. C15 relay board.
I have wired the VFD using this diagram from CNC4PC...
http://cnc4pc.com/Tech_Docs/C23R2toVFD2.pdfThe CNC4PC site shows an example of the ports and pins setup that shows pin 14 as the step pin which matches the wiring diagram for the spindle speed output on the C23(analog) to the VFD. The direction pin is where I need some help. The example CNC4PC indicates pin 8 for direction while the direction (CW & CCW) is handled on the wiring diagram by pin 1 and pin 16 which are the 2 built in relays on the C23. I only have 1 direction pin in the Mach setup screen, but have 2 different pins that appear to me to control direction (CW & CCW) going to the VFD. What is the correct pin number needed in the Mach setup screen?
Also since I am controlling speed with the VFD how do I setup the spindle pulleys part of the Mach spindle setup screen?
Thanks
Tom
