spindle hookup

[curtisturner]

I have a 2.2K spindle from china and am using the smooth stepper board, I can not find any where exactly how to wire the spindle control to the SS board for speed control and on and off


Thanks in advance

Hi Curtis,

I'm assuming that you also got a VFD with the spindle?

The VFD should have an input for a 0-10V dc signal that can be used to control the spindle speed. It probably also has inputs for enabling the
spindle as well.

What you need is something like the DC-06 DigiSpeed that I sell. It will take the step/dir spindle control signal from the SmoothStepper and convert it to an isolated 0-10Vdc control signal. The DC-06 also has a couple of small relays on board that can be used for controlling the start/stop or enable inputs on the VFD.

The VFD also probably provides a 10V dc supply that is needed by the DC-06, so you don't need the onboard dc/dc converter.

As to setting up the Spindle control in Mach3, have a look at the relevant sections in the Mach3 manual.

If you want to send me a pdf of the VFD, I can give you more detailed advise.

Cheers,

Peter.
