No real luck with my servo drives. Thought i had 3, but seems 1 is only moving in one direction. After spending so much time trying to nut them out, i think im going to cut my losses and get something else. I have 9 drives, and only 2 are running. In the docs i got with the machinen the previous owner seems to be chasing drives. Maybe they weren't very reliable. I would rather just get something i can be confident is going to work and be replaceable. Just sent an enquiry to mesa about 2 x 7i29. They are only listing 1 in stock, not sure if im able to get 2. Has anyone ran 7i29 with a 7i49 for resolvers instead of encoders?

I haven't used the 7i49 with the 7i29, but I do use a couple of machines with 8i20 drives and I am extremely happy with them.

The 7i29 store page doesn't seem to link to the manual, so here is a direct link.

A 5i24 with 2x7i29 on one header and 1x7i49 on the other would give you 4 axes and leave a header free for general IO (maybe a 7i44 and a 7i84). You would end up "wasting" the encoder inputs on the 7i29 and the analogue outputs on the 7i49, but I do the same on my machines and I am almost over it

Thanks Andy. I also have 7i44 and 7i84, so that should work. Now just to let go of days in the shed working on the drives, and replace them..... I sure i will also get over it... One day.

10 week wait on 7i29...sigh...
