I was not sure if I should post this in drives section or CNC section but decided to start here.
I have an Atrump cnc bed mill with a 3 hp spindle motor. Clearly not the top of the line stuff, but fits my needs.
The drive is a Delta VFD037B23A. Its a 5 hp drive, single phase input, running a 3 hp motor.
The machine is less than 2 years old and I decided to back up all the drive parameters. I found the drive setup to be an utter mess. I fixed most of it to my liking but there was zero motor thermal or overload protection. I did set it up to reduce rpm if motor amps exceed 200%, and added a load meter to the cnc controller screen, but otherwise there is no spindle motor thermal or overload protection.
So my question is how is this handled on other CNC machines? Could this be by design to limit spindle motor trips to prevent crashes? I would think that the machine would go into estop mode when spindle drive trips, which would not be great when taking a big cut, but what is the risk?
How would you set it up?
