5i25/7i76 spindle not working

Due to the kind support here my steppers are working, so I tried the spindle setup.
My VFD does not have DIR and ENA inputs, I set up 2 outputs for CW and CCW.
PNCConf was set on the Smart Serial Tab for spindle output.
Min Output limit was set to 0
Max Output limit was set to 4000
Scale was set to 4000
The max. RPM of my spindle is 4000 so I think this is correct.

I tried MDI: M3 S1000, I heard quiet beep from the spindle motor, which means VFD on, but 0 volts on the potentiometer input.
So the outputs are working, but between Spindle- and spindle out I measured 0 volts instead of the expected 1,25 volts.
My VFD has 3 connectors for an external potentiometer: Com (wired to Spindle-), Pot (wired to Spindle out) and 5Volts (wired to Spindle +)
The VFD is configured correctly, I used the same setup with my old USB CNC setup.

Many thanks in advance.

If you look at the spindle section of the hal file you will see that there are some mistakes (pncconf errors)
so the first step may be to update pncconf to the latest version...


One fairly obvious problem is this:

net machine-is-enabled => hm2_5i25.0.7i76.0.0.spinena

which should be

net spindle-on => hm2_5i25.0.7i76.0.0.spinena

another problem is this:

net spindle-vel-cmd-abs => hm2_5i25.0.7i76.0.0.spinout

which probably should be:

net spindle-vel-cmd-rpm-abs => hm2_5i25.0.7i76.0.0.spinout

Thank you yery much, the spindle works.
How can I update Pncconf?
I tried builldbot 2.6 (not master) and started Pncconf but the result for the spindle was the same as before.
