Title: About Spindle Control ?
Post by: Overloaded on December 12, 2007, 03:28:17 PM

Hello All,
I'm new at this so please don't LOL.    :D
Right now I have a 1/2 hp 110v motor running the lathe spindle, speed change by step pulleys.
I have a Reliance 1 hp DC PM motor with a control box that has a pot for speed adjustment.
Can Mach be connected to the three pot terminals in such a way as to have PWM control the rpm of the DC motor  ?
Like I said, no laughing.   :-\

what is the voltage to your controller, ie does the pot put 10V when fully open.
I think there are a few devices that Mach can control for spindle speed, PeterHomann does one and I think some of the breakout boards also have them onboard now.

Hood,
Looks like 14.8 V.
I'll check with Mr.Duncan, see if his C6 board will work for me.

Thanks
