Hello!
I'm trying to make heads or tails out of the documentation for the INS500 (can be found here: https://www.mycom-taiwan.com/docs/INS500%20cat%20082002-V1.11.pdf, also attached). I understand that MyCom did things a bit different and the driver can be configured with a switch to accept two different pulse trains as opposed to just one and a direction pin - I'm fine with that. What I don't get is how I'm supposed to wire the motor enable with the CO-, SEL-, and COM pins - that I just can't see from the PDF.
Also, I'm sure the first question that comes to mind is "What controller are you using?" Well, I'm building my own. I have a 3.3v microcontroller and a level converter to bring things up to 5v. I've used this circuit successfully with 2 phase drivers like the KL-5056E stepper driver, but I just can't see how to enable/disable the motor and control the SEL pin. I mean, the pdf shows that the COM pin supplies 5V for this purpose, but with respect to what? There is no ground pin available, so I can't see how that COM pin would get used.
Ugh, don't get it. Anyway, if there's anyone out there who can help me get this driver wired up correctly, I would greatly appreciate it. I'd really like to use this stepper/driver for the 5 phase NEMA 34 I already have, oherwise I'll probably just replace both parts with something a bit more modern.
Anyway, thanks in advance! Hopefully my questions make sense.
Sincerely,
Marshall
