I am a little confused on this. In the wiring diagram for the axbb-e has a relay with the hook up going to a u+ and u- on the spindle decoder.
1. What's a spindle encoder?
I am using a teknomotor 2.2kw spindle
Acs150 vfd
2. Is a relay needed to turn on and off the spindle when using uncnc software?
What would be the proper way to wire these?
Any help is appreciated this is the most confusing part of my setup and I always like to understand what I am working with.
