I had my Fanuc 420i rj2 connected to the pc (using kfloppy), and it work fine... last week i saw that with a vfd(spindle) on there were interference (electric noise) and the connection brake. But when turning of the spindle of the connection between controller was fine... until this week.
Now the connection between pc and controller doesn't work any more, i try everything i could think of,
- I check the cabe with a multimeter to see if it was working, and it was ok,
- i try to configure and connect through port2 using the same rs-232, dint work,
- i reinstall the dosbox and kfloppy files, dint change...
Question don't know if the electric noise made by the vfd demadge something... is it possible?
Can anyone help me, i really need to put that robot to work and fast....
