Peter I'm a bit tied up at the moment but a quick glance tells me that's covered round about reply #150 to this thread

gasmeter:
OK to answer the inhibit part of the question.

MP23 is for axis IV on connector X10
0 - Ref pulse inhibit
2 - Ref pulse inhibit active

A ref mark is traversed every full rotation of the sensor .
If there are multiple pulses the pulse inhibit can be controlled by a cam switch or similar.

I'm lucky enough to not need that as my encoder will give 1 ref pulse  per rev, so I don't need pulse inhibit.

Hi Andrew

I added to reply #156, so I hope that quote contains most of the info in one place to help others .
