Wiring a Chinese servo to a 7i77. Setup for yet another newbie

Just checked it again, did not notice that there is a normal output for Z (index) AND an open collector output, saw only open collector that evening, sorry my bad. Anyway i was trying to make it simple for him, due to open collector requiring resistors to be added and different wiring needs.
Back to it, the Z or index pins are 15 for enc+ and 16 for enc-.

The drive enable is so obvious now, thanks. Don’t know what was thinking.

How did you wire the enable pins?

Also make sure you have the correct motor selected in the programming. I am still looking for my parameter sheet. It is in a backup and I haven't located it yet.

I haven't wired the enable yet, still trying to get some idea how its supposed to work using a DMM. It looks like I should be sending pin 9 which is the positive supply from the drive to ENAN+ on the 7i77 and then ENAN- to pin 6 on the drive which is SRVON.
I assumed I'd be able to pick up a 12 or 24v signal from the drive though between pin 9 and ground but so far no luck so I'm still a bit lost as to what's going on.

The 7I77 drive enable pins (ENAN+ and ENAN-) are just a floating switch

Its usually a good idea to verify that you can enable /disable
the drive with a mechanical switch before wiring to the 7I77

Thats what I figured too. I thought I should be able to just bridge pins 6 and 9 on the drive and get it to enable. I'm away for a few days so I'll dig back into it when I get home

What I do is connect outputs to machine-is-on. That way relays get energized and I use the contacts to enable the drives, Its easy to blow those outputs, just ask me how I know. This way it is bullet proof.
