Title: How About Stepper Motor Driver Wiring DM320T?
Post by: xingyuiou3 on Jan 17, 2020, 10:52 am
I'm looking at the datasheet for the DM320T (https://www.oyostepper.com/goods-110-Digital-Stepper-Driver-03-22A-18-30VDC-for-Nema-8-11-14-16-17-Stepper-Motor.html). Anyone used them?

https://www.oyostepper.com/images/upload/File/DM320T.pdf (https://www.oyostepper.com/images/upload/File/DM320T.pdf)

I'm confused as to how to connect this to a 7i76e.
On page 4, I assume I would go with figure 3: connections to difference control signal.

+5v to Opto
Pul- to Pul
Dir- to Dir

and that's all I need? I don't need any wires from the 7i76e pul+ and dir+ pins?

Can I connect the vcc in series to 5 of these drivers from one 5v pin?

Finally, could I safely connect all the enable pins in series from one digital output pin? It's my understanding the digital io will be at field voltage so Ill need a resister (2k) per the data sheet.

You were good enough to provide a link to the datasheet stepper motor driver but you also need to provide a link for the 7i76e. I have no idea what that is.
