Fanuc · Series 0i-D/0i Mate-D Maintenance
This Fanuc Series 0i-D/0i Mate-D malfunction prevention alarm indicates that the control detected a command specifying a value exceeding the maximum allowed speed for a rotational axis or spindle.
Click steps to track your progress.
Examine the NC program (S-code, G-code) for any speed commands that exceed the machine's specified maximum limits.
Verify the machine's maximum permissible spindle speed and feedrate parameters (e.g., Parameter 3701 for spindle max speed) are correctly set.
Check the gearing or transmission settings in relevant parameters, ensuring they are correctly configured for the commanded speed range.
Temporarily reduce the commanded speed in the NC program to test if the alarm clears.
Ensure that the maximum speed set in parameters aligns with the physical capabilities of the motor and spindle/axis.
