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?

Yesterday i got a working Spindleloadbar on Probe basic with the VFDMod at my DZB VFD

I´m Happy. Thanks.

I’m trying to wrap my head around this . 
I installed Linuxcnc from the main iso for 2.9.2 ,    Is that upspxe -dev?
Do I have todo any thing to my install to use load_conv.comp.  Can I just install what’s needed ?
Sorta don’t want to have to start over just for spindle load gauge since the only other thing I need todo for my machine is m6 remap.

I just re-installed this morning from the new 2.9.2 iso and was able to do
sudo halcompile --install load_conv.comp

from the folder that i had the load_conv.comp in (In my case my config folder) and it worked nothing else was needed.

Could you share how I achieved it?

you have to do install the load_conv with
sudo halcompile --install load_conv.comp

and then you have to edit and paste that in your hal
loadrt load_conv

addf load-conv.0 servo-thread

setp qtpyvcp.spindle-load-indicator.max-val 100
net spindle-current => load-conv.0.amps
net spindle-load qtpyvcp.spindle-load-indicator.in-f <= load-conv.0.percent

Thanks for your reply. I understand that, what I don't know is where you get that spindle load value from, do you get it through MODBUS or through the analog output of the VFD?
