Comprehensive Guide to Mori Seiki EX Alarm Codes: Troubleshooting and Solutions

The service engineer, Kenji Tanaka, had seen the inside of a thousand machine shops. Grease under his fingernails was a permanent feature, and the whine of a high-speed spindle was his lullaby. But the DMG Mori Seiki NTX 2000 on the floor of Tanaka Industries was different. It was a beast, a five-axis symphony of German precision and Japanese soul. And right now, it was singing a song of pure fury.

Bar feeder is out of material, material is jammed, or the emergency stop on the bar feeder was pressed. EX0550: Chip Conveyor Overload

The coolant filter is clogged and needs cleaning or replacement. EXECUTE SAFE TEST

He peered into the gloom. There, wedged between the chain link and the guide rail, was a tiny, shattered ceramic chip from a broken milling insert. It was smaller than a grain of rice, but to a servo drive expecting perfect torque curves, it was a boulder. The machine hadn't crashed because Hiro had done anything wrong. It had crashed because a previous operator had ignored a dull tool, the insert had shattered, and the shrapnel had found a home in the magazine's heart.

The coolant tank fluid volume has dropped below the safe operating limit.

The contains machine-specific recovery procedures, while the separate Ladder Manual (if you have it) provides the exact conditions for each EX alarm. If these are lost, the original machine's documentation may be available through paid technical documentation services or directly from DMG MORI.

The hydraulic unit pressure has dropped below the safe operating threshold. Check the hydraulic oil level, the pressure gauge, and the pressure switch functionality.

: A failure in the gear-shifting mechanism, often requiring a check of the gear sensors (e.g., SQ22 or SQ23).

Look at the proximity switches on the chuck, turret, or doors. Clean away accumulated metal chips or sludge that might be fooling the magnetic sensors.
