At commanded S80 the frequency out from VFD should be about 32Hz and not as in picture 1.84Hz

50Hz / 125 (max speed in that gear) * 80 = 32Hz

So something is missing, scaling or ratio perhaps in comp or hal?

Is this possible?
Code:
setp gear1 => GB-2speed.0.motor-speed-out * 8.00 setp gear2 => GB-2speed.0.motor-speed-out * 6.25 setp gear3 => GB-2speed.0.motor-speed-out * 4.65 setp gear4 => GB-2speed.0.motor-speed-out * 3.70 setp gear5 => GB-2speed.0.motor-speed-out * 2.77 setp gear6 => GB-2speed.0.motor-speed-out * 2.22 setp gear7 => GB-2speed.0.motor-speed-out * 1.68 setp gear8 => GB-2speed.0.motor-speed-out * 1.33 setp gear9 => GB-2speed.0.motor-speed-out * 1.00 setp gear10 => GB-2speed.0.motor-speed-out * 2.10 setp gear11 => GB-2speed.0.motor-speed-out * 1.66 setp gear12 => GB-2speed.0.motor-speed-out * 1.25 setp gear13 => GB-2speed.0.motor-speed-out * 1.00

Don't think so.

You should most likely look inside the component how the motor-speed-out is calculated.

Maybe you did that already to end up with the factors here, but you can use the halshow to
show the values of the output pins.
And if there is something wrong in the output pins values, and the right logic with the gears work,
you need to look in the code how the wrong value is calculated. It should be possible to follow,
there aren't too many lines of code.

Can you show a screenshot of halshow with all the input pins and output pins of the component
shown when there is an output that troubles you?

S80 commanded
output of 2500 from comp is way off, should be about 640 if my calculation is correct and still it is not acting so as i only get 1.84Hz.
