I would set the 100% mark to the spindles 100% duty cycle amperage rating. some spindles have the capability to run at levels up to 150% or more amperage for short periods of time. but either way 100% should be the max continuous amperage rating allowed in the drive/motor manuals

ok thanks, my spindle is 400V 4.5kw 10A

so i set this percent = round(amps/0.10); for 100%

so my VFD has a Digital current output, i will wire this to my mesa 7i76e input.

so find found this hal code

loadrt load_conv
addf load-conv.0 servo-thread

# net vfd.Rott => spindle.0.speed-in
setp qtpyvcp.spindle-load-indicator.max-val 125
net spindle-current => load-conv.0.amps
net spindle-load qtpyvcp.spindle-load-indicator.in-f <= load-conv.0.percent
net spindle-current => qtpyvcp.spindle-load-indicator.in-f
# net spindle-speed-fb => qtpyvcp.spindle-encoder-rpm.in

so i must set my input pin to spindle-current?
is that right?
