PoKeys / Spindle VFD feedback
« on: November 12, 2016, 07:13:30 AM »
Hi there!!!
I own a chinese 800w VFD since 2012 and running like new, now I have a new cnc ethernet controller, I am already able to controle the spindle speed and start/stop from Mach3 but I would like to have the rpm feedback from the vfd into the mach3.
As the VFD screen shows the current rpm of the spindle, how can I get that info, which are the pins on the vfd and what time of signal is it? Pwm or analog?
Thanks
