This alarm indicates that the time taken for the spindle to change gears has exceeded the allowed limit. This can point to either an incorrect setting for the monitoring time or a mechanical problem within the spindle gearbox.
Click steps to track your progress.
Review the gear change monitoring time setting and increase it if it appears too short for the operation.
Inspect the spindle gearbox for any signs of mechanical issues, damage, or blockages.
If mechanical issues are suspected, consult a service technician for further diagnosis and repair.
