Mach4 General Discussion / Mach 4 ESS C82 Huanyang VFD PWM Spindle setup

« on: February 23, 2021, 02:45:04 PM »

CNC4PC supply a wiring diagram for a C82 and Huanyang VFD.  I have configured the VFD to operate correctly from its keypad.  However, I am entirely confused by all the posts / videos as to the Mach 4 ESS setup.  Please anyone running a recent (4517) Mach 4 & (v270) ESS -- spindle control setup?  The C82 uses Port 1 pins 14 & 16 as spindle relays, plus provide a 0-10V analog output (not sure what pin this is mapped to).  Although the supplied C82 pin config diagram labels the Port 1 relays as PWM and Dir, I have my C82 jumper set to "international" which implies these relays will be FOR & REV. ...That is how they are connected to the VFD.  And that is as far as I can go.  I would very much appreciate some help.
