Your custom.hal should be:
If output speed will be wrong take your attention to Multiplier and Divider parameters in vfdmod ini.
loadusr -W vfdmod my-config-file.ini
net spindle-cmd-rpm => vfdmod.spindle.rpm-in
net spindle-at-speed <= vfdmod.spindle.at-speed
net spindle-cw spindle.0.forward => vfdmod.control.run-forward
net spindle-ccw spindle.0.reverse => vfdmod.control.run-reverse
If output speed will be wrong take your attention to Multiplier and Divider parameters in vfdmod ini.

I changed these two lines - I forgot to rename the pins in linuxcnc 2.8 before. I left a multiplier 1 and a divisor 1 everywhere, so they shouldn't affect the values.
Now the program gives a signal to the inverter and the inverter switches to RUN and FOR but after a second there is a communication error again (code 110) and the connection is red. Now I set the minimum speed to 50 and this value is given and after pressing the inverter direction icon, the motor starts with the minimum speed but stops responding to subsequent commands and I have a connection error.
Is it possible that the vfdmod program is using a log write function not supported by my inverter? I checked that I can use function 06 and multi-save 10.
My config file:
Thanks again for your interest and help. I am very beginner, hence problems at every step

Now diode for Spindle at speed is green

It looks like the reason is electrical noise, like here: forum.linuxcnc.org/24-hal-components/391...communicaiton#168822Now the program gives a signal to the inverter and the inverter switches to RUN and FOR but after a second there is a communication error again (code 110) and the connection is red.
No, I don't think so.Is it possible that the vfdmod program is using a log write function not supported by my inverter?

ok, I disconnected the engine completely and the connection interruption problem disappeared. But I still can't change the rotation. Start and RUN forward and reverse works fine but RPM remains at the minimum setting

If your custom.hal includes line below, all should work
If not, check command frequency register address. It's also may be an additional option in your vfd, like command frequency source - potentiometer, keyboard, or rs485 line.
net spindle-cmd-rpm => vfdmod.spindle.rpm-in

Also try to play with Multiplier in [SpindleRpmIn] section, try 10, 100, 1000. Is something changes? Don't forget to remove ";" character in ini.

It works Thanks a lot, you are great Of course, it's my mistake because changing the entries in custom.hal according to what you gave above, I omitted the changes regarding the first line. There is an entry from the Github page, probably from version 2.7. These pin renaming are causing me problems. Now it's ok. I just have to deal with the shielding of the converter-motor cable and the noise filter. Will something like this be good?
