I recently decided to upgrade to a bigger spindle motor with a VFD (HUANYANG), controlled by a cnc4pc c11 card. After a steep learning curve and some other issues I finally got the VFD set and the elusive +10V analog output out of the c11 to control the motor speed. As far as I can see, when I increased/decrease the spindle speed in Mach3, I can measure the voltage going up and down, as well as the frequency in the VFD, but the motor does no turn.
I can operate the motor manually using the VFD panel, but when I try to operate it remotely with the analog input, it doesn't. I know that there's got to be a PD setting that needs to be changed, but I cannot figure it out. Anyone...please!
