Title: Lathe Spindle AC servo Mach3 pokeys
Post by: Lotus23 on December 30, 2021, 08:18:34 PM

Hello
I have a Chinese 130ST-M07725 AC servo for a lathe spindle requiring step & Dir. So far I have had no luck in getting it to work, pokeys documentation seems a bit sketchy on this.
I assume I connect the servo drive to a motor port, but which one? Or do I set a generic digital output instead?
There doesn't seem to be any details for a spindle in the pulse engine window, just axis drives.
thanks in advance.

Pokeys will not do a servo spindle with step and direction you need to set up as plus minus 10 volts

Hi,


Are you sure about this?

I was told by PO-labs they do not support a servo spindle and threading . Set up your spindle using +/- 10 and it will work . You have to change your servo driver setting.I have an ac servo motor driving my spindle . I had to add an encoder to my spindle running 1;1 and my drive from the servo to the spindle is also 1;1 .

Yes, yesterday I got the same response from Polabs as well. However, they also told me that they are planning on this matter.

So I do use a servo to drive my lathe spindle .I control with plus mins 10 volts . You need to set up your servo driver to do speed mode .

My control board (M16 with Pokeys57E) doesn't support -/+10v. Only 0-10v. So to convert it to -/+10v I used a DPDT relay, like the one below.

I really hate relays (I have my own reasons) but I guess a relay is the only way to go.

It depends on what your servo driver needs .I am also using a cncpc M16  . I have Lichuan AC servo and motor

Mine is a Chinese drive (AASD).
