It's mentioned in the 8i20 product page as basically turning the 8i20 into a full featured servo drive but it doesn't actually seem to exist. I've seen a few questions about it on here but no responses. Does it or will it exist?
I use the 8i20 as a spindle drive for a BLDC motor with added encoder. It's working pretty well but has some limitations in my application. It may be a 7i76e speed thing or my limited PID tuning skills but I'm currently limited to a spindle speed of 3000rpms and some operations cause the spindle to act like a rubber band as the current ramp takes a moment to spring back on demand. I'm thinking the 8i20 running in velocity mode with the 8C20 might be better suited for a spindle.
