Mine looks like this, is that a problem?
# ---ARC VOLTAGE ENCODER---
net plasmac:arc-voltage-in <= hm2_7i76e.0.encoder.00.velocity
setp hm2_7i76e.0.encoder.00.counter-mode 1
#setp hm2_7i76e.0.encoder.00.filter 1
setp hm2_7i76e.0.encoder.00.scale -1

So I finally got it working.
Problem is I modified a config file from linuxcnc 2.8
So I ran PNCconfig. And made a new configuration from scratch.
I figured out for some reason F/1 does not work.
Somehow changes to Qtplasmac don’t work if you run the configuration again.
Is this a bug?
I changed Jumper to F/32 and Made another configuration from scratch. Now it works perfectly.

Change from F/1 to F/32
And change to the 0 Volt frequency
Do not influence voltagedisplay.
However the change to 0 V frequency can be seen in the qtplasma…..new file.

That is the expected behaviour:

My relay for arc on has a led with a series resistor parallel to the coil.
do I still need a flyback diode?
