VFD controlled by Mach3. I Need to lower my 0-10VDC to bring the actual speed (requested in mach3) to the speed that I actually get (as shown by my Index Pulse card)
Its all working, by I cannot lower my voltage enough either on my CNC4pC board or my dedicated 12vdc PS to "tune" the spindle (actually RPMs) to the RPM's I request.
Can I just put a resistor on the PS output? or on the 0-10VDC output on my CNC4pC card? if so, what value would I try to get an approximate 20-25% reduction in voltage output?
Thanks,
Nate.
