Fanuc · Series 0i-D/0i Mate-D Maintenance
This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the machine lock function is active for the Z-axis during a tool change operation. This is an unsafe condition prevented by the control.
Click steps to track your progress.
Deactivate the 'Machine Lock' function before initiating a tool change sequence on the Z-axis.
Review the PMC ladder logic for the tool change sequence to ensure it correctly disables machine lock during the operation.
Check the NC program for any 'Machine Lock' commands issued during a tool change operation that could trigger this alarm.
Manually jog the Z-axis (if safe) to ensure it is not stuck, and then reset the alarm.
Verify the status of the 'Machine Lock' input signal in the PMC diagnostics to ensure it is not active when it shouldn't be.
