DC Motor speed control (Resolved)

Post by Upnorth »

I just ordered another acorn but just noticed what may be a potential problem. I'm using a KBWT-240 speed control to control a 180 VDC mptor.

The problem is I just noticed that the acorn only has a 0-10 volt output for speed control. I need a 0-5 volt output for the speed control. Can I use something like a voltage divider to halve the voltage or should I look somewhere else for a solution?

Thanks

Acorn will do 0-5 vdc analog out, no problem, just select which one you want with the Setup wizard.

PWM out is also now available as well for Spindle and/or Laser control.

Thanks Keith.

I looked on the features part of the website and I only saw the 0 to 10 volt spec. I checked the wizard on my milling machine and there it was.

Thanks for pointing me in the right direction.
