hi guys
have been lurking around here for a bit. there are some great conversions and very knowledgeable people kicking around here.
i have a BP clone mill that i have converted using 400w yaskawa servos. so far all going well, only a couple of issues that were more related to hardware than anything else.
due to how user friendly mach 3 is i have got through the conversion reasonably pain free but this latest issue has me stumped.
i have been running the mill for a couple of months and now want to get the spindle speed up and running. i was only using the dc03 from peter homann for on/off duty but now want to use it to vary speed.
i have had email conversation with Peter about my issue but it looks like his board is set up, wired and should operate correctly. i have also email him some screen shots of my mach setup and it all looks right.
i have taken pics of my dc03 setup and he confirmed it seems correct but it doesn't matter what i do all i get is 100% speed output from the unit. when i power up the board i get the correct flashes and when i activate the pins i get the fast flash saying the board has signal. if i deactivate the pin in mach 3 the flash on the dc03 changes to say it is getting no signal.
so my question is how do i tell if machi3 is outputting the PWM to the board?
i am sure it will be something basic but i have spent literally hours trying to get this thing working but no joy. i have used a pot on the inverter to confirm i have the inverter set correctly and when i put the dc03 in trimpot mode and turn the on board pot the speed changes accordingly. got me stuffed
any ideas?
