I have a Fanuc OM-A controlled VMC. When I bought it was told the controll board was bad. Tha machine was sitting dormant for some time and the batterys had gone dead. I replaced the control board and re-entered the parameters. As I have read the diagnostics need to be entered first. However two of the parameters I need to enter keep changing. Parameters D320 D330. The machine seems to be in lockout or estop mode (regardless of estop button) as the servo drives, pneumatics do not power up. Any help would be appreciated.
Thanks
Kevin
