Mori Seiki Ex Alarm List ((link)) -

On Mori Seiki machines (typically utilizing Fanuc, Mitsubishi, or proprietary MAPPS control systems), alarms are generally split into internal and external categories.

Triggered by low coolant levels in the main tank, high coolant temperature, or a tripped thermal overload on the coolant pump motor.

Main hydraulic system pressure has dropped below the safe threshold required to hold the chuck, actuate the tailstock, or change gears.

Core control or drive errors (e.g., servo errors, axis communication faults).

1. Check the way lube reservoir level.2. Inspect lines for physical leaks.3. Verify pump operation and pressure switch functionality. HYDRAULIC PRESSURE DROP

The tool turret failed to properly seat and lock back into position after indexing.

The automatic lubrication system failed to build pressure within the designated time cycle.

Spindle drive alarm is present. Check the amplifier in the cabinet. This public link is valid for 7 days

Flow switch in the coolant system is detecting low flow. Check pump, nozzle blockage, or coolant level.

The automatic way lubrication system failed to build up adequate pressure within the designated time frame during a lube cycle.

Most proximity sensors on Mori Seiki machines feature a built-in LED light. Manually actuate the mechanism (if safe to do so) to see if the light switches on and off, validating that the sensor reads target metal. Step 4: Clear the Alarm Safely

Lack of oil or pressure in the tailstock movement system.

The Automatic Tool Changer arm or magazine motor encountered excessive resistance.
