General Mach Discussion / Need Help Controlling Spindle
« on: December 24, 2011, 07:04:59 AM »
Ok I've connected my VFD to my breakout board but cannot seem to get mach to do anything.

Attached are pictures of the terminals of both. I have wired:

Vin to +10V
Out to FiV
0V to GND

CP1 to FWD
CP2 to GND

If I'm honest this was just my best guess at what should go where.

problem is i'm not sure if I'm not setting it up right in Mach or if i've wired it wrong so it can't work....

General Mach Discussion / Connecting Breakout board to Speed controller
« on: December 20, 2011, 03:15:04 PM »
Hi. I'm so close to finishing my CNC now but i have one or two issues.

I have a UIM2901 Breakout board which seems to indicate it can control spindle speed. However I am unsure how to attach it to an inverter/VDF I have (Manual Included in attachments)

I've tried posting at CNCZone but have yet to get a reply.

Can anyone here help?

If it is not possible to control through the Breakout board and hence Mach would it be possible to make a simple on off switch and maybe a potentiometer speed controller?

Thanks
