7I76ED XYZ 0-10V Spindle was created by chili023
Hello everybody,I have a XYZ Mill with 4 Stepper and a 0-10V VFD.
I used pncconf to get my initial setup and all steppers work.
I used the desired spindle outputs and was able to get a voltage signal withas a hal command.However the spindel output does not react to the commands from the gui.
I then tried to edit my custom.hal:This tied hm2_7i76e.0.7i76.0.0.spinout to the exact value of spindle-output.The output wants to have 0-100 values, so I wanted to scale by editing my custom.hal withand added to the maschine.iniApparently this was not of success.Do I need to use a loadrt scale for the output?

I used the desired spindle outputs and was able to get a voltage signal with
setp hm2_7i76e.0.7i76.0.0.spinout 10 or 100.I then tried to edit my custom.hal:
net spindle-enable hm2_7i76e.0.7i76.0.0.spinena
net spindle-output hm2_7i76e.0.7i76.0.0.spinoutsetp hm2_7i76e.0.7i76.0.0.spinout-minlim [SPINDLE_0]OUTPUT_MIN_LIMIT
setp hm2_7i76e.0.7i76.0.0.spinout-maxlim [SPINDLE_0]OUTPUT_MAX_LIMIT
setp hm2_7i76e.0.7i76.0.0.spinout-scalemax [SPINDLE_0]OUTPUT_SCALE[SPINDLE_0]
P = 0
I = 0
D = 0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 0
MAX_OUTPUT = 20000
OUTPUT_SCALE = 25000
OUTPUT_MAX_LIMIT = 100
OUTPUT_MIN_LIMIT = 5

With an output scale of 25000 and a output max limit of
100, the maximum output voltage would be 40 mV
Typically you would set the output max limit to the same
value of the output scale

Ok.
But why is spinout still going to 20000?
And the maximum value of spinout is 100.
So what do I miss?

The output max limit limits the analog output to V*max_limit/output_scale
where V is the applied voltage to the analog output circuit (usually 10V)
That is, if you set max-scale to the RPM at 10V (25000 in your case)
setting the max limit to 100 would limit the maximum RPM to 100
