Hi All,
I have a customer who has an old Mori MV-40e which uses a variant of the Fanuc 21-m. Any axis connected to the Servo 3(Z Axis) port on the A16B-2201-0721 card results in the DRO changing when jogging or running G-Code but no movement. I would have expected a following alarm or some other type of alarm but I am not. The machine seems perfectly happy with what it is seeing. I recommended replacing the A16B-2201-0721 but would like to see what you guys thought before doing so. I'm not a huge fan of just firing the parts cannon.
I have confirmed the issue is not with the Servo Drive by swapping the connections with the Servo 2 port and the Z-Axis works fine.
