Hello all,
I have an older Journeyman 300 that I am trying to figure out if I am able to use the Existing Spindle drive with MACH 3 or do I have to get a different drive does anyone have any ideas for running DC spindles?

Can you post a picture and model number of your drive?

Normally they take either 0-10VDC or +/- 10VDC command signal. With the correct breakout board, 0 - 10VDC is easily available for Mach3.

Or use something like this for step & direction control. https://www.automationtechnologiesin...er-dg4s-016035

That motor shows a Tach, is this one of the old voltage feedback drives?
These were generally as Jim says, +/-10v analogue input.
I see this is posted in the Kmotion/Kanalog forum, are you using this type of controller?

I was going to use a smooth stepper. I can get a picture of the drive shortly but their are a lot of inputs that I’ll have to figure out how to get it to function. This machine I would say is from the 80’s.

Would a gecko drive work for this application?

The Gecko 320X drive is only 80 volts max input, your motor is 140V. So would most likely not be a good fit in spindle application.


This drive is 160V max input and would be a better choice. https://www.automationtechnologiesin...er-dg4s-016035

...Westamp 5810?

Modern DC drives do not use the tach feedback, I usually removed the tach brushes to avoid any future problems etc.

So a motion controller would work to drive this motor than? I assume the smooth stepper should be able to run the drive with Mach 3. I could possible use the DG4s to drive the DC servos for the axis as well?

Assuming that the axis drives are within the voltage and current rating of the DG4 drives, then they should work fine.

I have dc4 drives.. works verry good at 180v.. you just need to instal a encoder to that motor.
