General Mach Discussion / Mach3 controls and PWM

« on: April 01, 2013, 08:42:39 PM »

I have installed a VFD on my knee mill and using a PMDX 126 controller card with the PMDX 107 spindle card added to it. the VFD works from the test button on the 107 card and when I give a M3 command the spindle comes on. I have noticed when I move the Spindle override slider up the spindle motor slows down and move it down it speeds up. I'm not sure if that is normal or not but it seems to me like its backwords? the other problem I have is when I give it an S command like ( S 800 ) I get a message at the bottom of the screen saying. ( Error on line 1 - wrong number of arguments or invalid property assign) and the spindle motor will not change speed if I give any other S command. it will stop with M5 and backup with M4. and the 107 card has a LED on it for PWM and it will get brighter and dimmer when I slide the override down and up. any ideas?
Thanks.
