If i loop S1 S2 REV FWD should there be any other wires also or just the loop.
Cheers

Don't do that.!

The S1 and S2 are just set speed ranges determined by parameters in the VFD and you choose one or the other not both at the same time. Rev and FWD are what they say and obviously, you don't want both on at the same time.!

However, you have an Analog 0-10V speed output on the AXBB-E which you can use so you don't need the S1 or S2.

REV is not recommended as it will unscrew the collet nut so most don't use this either. So you only need FWD which I explained how setup further down, and for setting the speed you use the 0-10V output which connects to the Analog inputs on the VFD. There may be parameters that need changing in the VFD wire it as shown in the pic and if it doesn't work let me know and I will look at the VFD parameters.
