These settings depend on the ini values in the SPINDLE_0 section

setp hm2_7i94.0.7i83.0.1.analogout0-maxlim [SPINDLE_0]OUTPUT_MIN_LIMIT
setp hm2_7i94.0.7i83.0.1.analogout0-minlim [SPINDLE_0]OUTPUT_MAX_LIMIT
setp hm2_7i94.0.7i83.0.1.analogout0-scalemax [SPINDLE_0]OUTPUT_SCALE

Typically you would set OUTPUT_SCALE to the spindle RPM at 10V
and OUTPUT_MAX_LIMIT to the same value. For 0 to 10V spindles,
OUTPUT_MIN_LIMIT would be 0, and for +-10V spindles, OUTPUT_MIN_LIMIT
would be the spindle RPM at -10V (probably the same as OUTPUT_MAX_LIMIT
with a minus sign)

You can drive LEDs directly with 7I73 outputs but you need a series current limit
resistor, say 220 Ohm

Thanks PCW that worked once I corrected my typo's!
setp hm2_7i94.0.7i83.0.1.analogout0-maxlim [SPINDLE_0]OUTPUT_MAX_LIMIT
setp hm2_7i94.0.7i83.0.1.analogout0-minlim [SPINDLE_0]OUTPUT_MIN_LIMIT
setp hm2_7i94.0.7i83.0.1.analogout0-scalemax [SPINDLE_0]OUTPUT_SCALE

I also solved one of my other questions:
Question 1:  Is there a way to add halui pins and add them to Axes for the second spindle or is this something I will need to build in glade etc?
I needed to add SPINDLES = 2 to both the EMCMOT & TRAJ sections in the ini file.  I only had the EMCMOT one loaded.

Now continuing with the multiple spindles theme! 
I would like to make a second set of the spindle controls in Axis for the second spindle including the override slider.  I have searched for a few hours and I have not come across anything that would show how to do this.  If I missed it please add the link below!  I also need to setup a second set of values in the DISPLAY section of the ini for MAX_SPINDLE_OVERRIDE, MIN_SPINDLE_OVERRIDE & Default Spindle Speed.  My second spindle has a low of 10000rpm so the default of 200 wont work.

Also still looking for thoughts on this question.  My thought is if I'm controlling the spindle with a 0-10V signal the drive will control the spindle i=11.0ptndependently with the encoder signal, and worst case I will only get true spindle speed if I were to tap into the encoder signal. 
   
Question 2:  I noticed that there is an encoder on my main spindle and I have the pin out the 3CN connector see pics.  I am assuming that I feed a +-10 volts to the 626MTIII Drive and with the encoder input, the Drive is able to control speed etc independently.  Can I tap off of these signals back to an encoder input & linuxcnc to get an actual speed and link up for ridge tapping?
