Good after having everything assembled on my cnc, the following happens to me.

When I turn on the VFD, the Arduino loses communication with the PC and I have to turn off the software and disconnect and reconnect the communication cable between the PC and the Arduino.

the same thing always happens and I can't work.


Has this happened to someone or do you know what it could be?

It's call EMI noise you have bad wiring VFD Drives need special care when wiring or this will happen a EMI Power Filter is required mounted close to the VFD Drive input power supply

The VFD Drive to the Spindle requires a special Shielded cable and the shield correctly Grounded at both ends this cable needs to be 4 wire plus Shield correct use of Ground is required for the spindle VFD Drive power supplies Etc.
