Spindle Controller

[xitian]

I am getting ready to CNC my RF-30 mill with CNC using Gecko drives and a G-rex. I would like to be able to control the spindle too. The motor is a 2HP running on 220V pulling 15Amps. Can anyone recommend where I can get a VFD and controller? I think that is what I need but I'm not clear on all of the electronics....

Thanks!

Hi


Assuming it is an AC motor, have a look at Automation Direct's GS2 range of VFDs.

Then to control the spindle speed from Mach3, have a look at the DigiSpeed-XL I sell. Apart from converting the spindle speed control signal from Mach3 into a 0-10V isolated dc control voltage, it also contains circuitry for;
1. manual control
2. relays for direction control
3. Index sensor connection and conditioning circuitry.
