General Mach Discussion / VFD Speed Control

« on: November 22, 2006, 09:36:12 AM »

So i just finished up installing my VFD.  My spindle is a 24000rpm spindle.  The VFD speed control uses a 10v signal to tell it the speed.  But some reason i cant get it to go the right speed that mach tells it. 

If i set mach to max 24krpm and tell it to run 12krpms its is actualy running at 15krpm.  But if i twist the nob on the speed controller going to the VFD so that its running at 12krpm instread of 15k then it runs slower than 24krpms when you tell it 24k.

Id like to get it running within 500rpm of the actualy speed typed in.  Is this possable?

My breakout board is simple.  All it has it the lpt port and blocks to connect wires.  I do not think it has a analog output.

Well i just ordered a Ekstrom Carlson Spindle to replace my porter cable.  I just couldnt deal with the run-out any longer.

Can anyone give me a rundown on the best way to wire the VFD to mach3?  The simplist way.

Thanks for the quick response guys.  I am upgrading from a older mach3 to a newer mach3.  Hopefully i do not run into any issues.  The only thing i can think of i might run into is i changed my hotkeys around.  Hopefuly that transfer over.  I think there is a second file i should backup.  The one that has the mach3 hotkets on it.

General Mach Discussion / Easiest way to control spindle rpm.

« on: August 29, 2006, 05:16:10 PM »

Hello,
I would like mach to control my spindle speed.  Ive herd people talk about vfd's and stuff.  but i know nothing about them.  If anyone can point me in the right direction it would be great.

I have a 3.25 hp porter cable router.  About the only thing i know about it is it pulls 120v and 15 amps.  Right now its hooked up on a solid state relay to control on and off. 

Thanks,

i have the same problem.  the voltage is so low that the 110v going to the spindle interfers with it i think.

That worked great Hood.  Thanks for the help.  Now i got my pendant working perfect.  Only thing left is to install my safety charge pumps to turn on my controller soon as i open mach3.  I want to setup this machine so its a 1 button turn on process.
