Hi thanks Richard . I am running a single phase 240v? supply to inverter running a 3 phase motor in delta. My 5 volt system? ?is not grounded as I am using? plastic enclosures not sure about grounding the 5V. The PSU 48V? and PSU 5V and? 2 stepper drivers are all in one plastic enclusure

Just to determine the situation have you changed to a 3 phase motor but
running single phase into the VFD?
If so which VFD?
How good is your grounding on any part of your system?
Is your 5v 0v connection grounded? How are all of the ground wires
connected, Star?
What is the location of various parts of the system? Encoder, Spindle
motor, Arduino control, Stepper Drives and PSU.
Good luck Richard
