[ Vfdmod ] An easy VFD control over MODBUS RTU

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.

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?
