: Use the right arrow softkeys to find "OPERATIONAL HISTORY" or "ALARM HISTORY". Execute Output

Hot chips, sticky coolant residue, and fine metal dust frequently collect on proximity sensors, causing false readings. Clean the sensors using a lint-free cloth. mori seiki ex alarm list

In a CNC environment, chips, sludge, and coolant constantly bombard sensors. If an EX alarm points to an unexecuted mechanical action (e.g., tailstock not home, tool changer not indexed), locate the proximity switch. Clean away any metallic chips, check for loose wiring, and ensure the sensor target is within the correct sensing distance (usually 1–2mm). Step 4: Perform a Hard Power Cycle

The Mori Seiki EX alarm list is a valuable resource for machine operators, providing a comprehensive guide to troubleshooting and resolving issues. By understanding the alarm codes and messages, operators can quickly identify and address problems, minimizing downtime and optimizing machine performance. Regular review of the alarm list, combined with best practices for troubleshooting and maintenance, can help ensure the Mori Seiki EX machine runs smoothly and efficiently.

Keep a printed EX alarm quick-reference sheet near your machine’s electrical cabinet. Train every operator to differentiate between an EX alarm (usually a recoverable condition) and an NC alarm (requires deeper technical intervention). And finally, use historical EX alarm data to drive predictive maintenance—because the best downtime is the one that never happens.

The door lock signal was not confirmed within the allowed time. PANEL ALARM General error with the flat operation panel or its I/O. ELECTRICAL CABINET OVER HEAT

Triggered when the way lube reservoir is empty or the lubrication pump fails to build adequate pressure within a set time cycle. In a CNC environment, chips, sludge, and coolant

Occurs often after power-on. A simple cycle of opening and closing the front door will clear this.

Check for mechanical tool interference or heavy weight imbalances on the turret. Check the turret clamp/unclamp proximity sensors located inside the turret housing sheet metal. Verify hydraulic pressure to the turret clamping mechanism.
