These values are still from the pncconf wizard, I think it is for a spindel connected via the 7i76e, didn't clean the files yet...

Finally I found out to set PD0144 to 3000, mine was set to 1440. According to the sound of the spindel
I think it is just the display showing the correct values.

Hi Strahlensauger.

I guess you are from Germany like me. If you have any further question you can pm me in German.

I have a chines 2,2kw spindle work with RD485 on a standard Huanyang VFD. I switched to Hitachi now but i keep all configs.

Your .ini part for the spindle look like this (refelct the VFD settings you made)

[SPINDLE_0]
P = 1000.0
I = 0
D = 0
FF0 = 1
FF1 = 0
FF2 = 0
BIAS = 0
DEADBAND = 0


MAX_OUTPUT = 24000.0
OUTPUT_MIN_LIMIT = 6000
OUTPUT_MAX_LIMIT = 24000
OUTPUT_SCALE = 24000

Your custom.hal like this:

loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 38400 
net spindle-vel-cmd-rpm 		=> vfd.speed-command
net spindle-cw spindle.0.forward 	=> vfd.spindle-forward
net spindle-ccw spindle.0.reverse 	=> vfd.spindle-reverse
net on spindle.0.on 			=> vfd.spindle-on 		=> hm2_7i76e.0.7i76.0.0.output-13 #thats my solenoid to start the water pump for cooling
net spindle-at-speed 			<= vfd.spindle-at-speed

Here the spindle parts in my machine hal:

net spindle-at-speed          =>  spindle.0.at-speed
#net spindle-vel-fb-rps         =>  spindle.0.speed-in
net vfd.Rott         =>  spindle.0.speed-in
net spindle-index-enable      <=>  spindle.0.index-enable

# ---Setup spindle at speed signals---
# done in custom hal
#sets spindle-at-speed true

Best,
Udo

No it is not, it was removed due to way to many requests over PM, and that defeats the purpose of an open forum.
