Mori Seiki Ex Alarm List __exclusive__

Machining environments are highly volatile. Fine metal chips and heavy coolant spray frequently coat proximity switches (on the chuck, doors, and tool changers), causing false EX alarms. A quick spray of cleaner or a wipe down fixes a massive percentage of these errors. Summary Table: Quick Reference EX Alarm Code Common Meaning Primary Action EX0001 Door Interlock Error Clean door switch; ensure fully closed. EX0015 External Emergency Stop Reset all E-stops on machine & accessories. EX0151 Hydraulic Pressure Down Check hydraulic oil level and pump gauge. EX0170 Way Lube Low / Fault Refill way lubricant reservoir. EX0201 Coolant Level Low Add coolant; check float sensor for chip buildup. EX0310 Chuck Unclamp Fault Adjust actuator proximity switches; check stroke. EX0520 Turret Index Error Check for mechanical obstruction or low hydraulics. If you want to isolate a specific code, let me know: The exact EX alarm number showing on your screen

Incorrect work offsets, programming error, or a failed soft-limit parameter. EX0220: Axis Interlock Active mori seiki ex alarm list

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. Machining environments are highly volatile

This article provides a comprehensive overview of the (also commonly found on DuraTurn and DuraVertical series), focusing on interpreting these "EX" codes and offering troubleshooting steps to get your CNC machine back into production. Summary Table: Quick Reference EX Alarm Code Common

In the world of DMG MORI service documentation, the term is searched thousands of times each month by engineers desperate to decode a flashing "EX 1050" or "EX 1402."

If it persists, re-examine the PMC diagnostics screen to see if another interlock condition remains unfulfilled. Preventive Maintenance to Reduce EX Alarms

Always start by verifying the obvious: hydraulic fluid levels, door closures, and chip conveyor jams. When those fail, access your machine’s PMC message history or log into the DMG MORI service portal with your serial number. For the rare, undocumented EX alarm, reading the PLC ladder directly is your ultimate fallback.
