I am wanting to get my Hurco to run a bit faster, especially with trying to run aluminum dry. I need to setup the spindle and servo load meters. They are an analog signal from the devices 0-10 volt. I know I will have to convert the analog signal back to a digital signal for my PPMC. I though Jon had told me it can handle 10bits, so I was going to find a converter that can at least handle that. I am torn on using it as a real-time component as its not required for motion, just a tool that can aid in me pushing the machine a bit closer to the limits and reduce the instances of going to far.

this should be an easy converter to use.
What do yall think? this is a rough idea at the moment.
Thanks!
I was thinking about
Code:
# spindle LOAD display
addf lowpass.1 servo-thread
net spindle-load ppmc.0.din.28.delta conv-s32-float.0.in
net spindle-load conv-s32-float.0.out mult2.0.in0
setp mult2.0.in1 1 # (0-10V)
net SpindleLOAD mult2.0.out => lowpass.1.in
setp lowpass.1.gain 1
newsig SpindleLOAD float
linkps lowpass.1.out => SpindleLOAD
Meter
