The Ultimate Mori Seiki EX Alarm List Guide: Troubleshooting and Fixes

Check the hydraulic pressure gauge (typically should be around 3.5 to 4.5 MPa depending on the machine). Check the hydraulic fluid level reservoir. Inspect the pump motor for tripped thermal overloads in the electrical cabinet. EX0170 - Lube Pressure Down / Way Lube Low

Ensure a part is properly loaded and clamped. If the part is clamped but the error remains, adjust the physical positioning of the chuck clamp/unclamp proximity sensors at the rear of the spindle cylinder. EX0243: Tailstock Spindle Quill Lubrication Error

When diagnosing an EX alarm, always check your machine's specific electrical schematics and ladder diagrams. Mori Seiki customises these codes depending on the machine generation (e.g., SL, NL, NLX, DuraTurn, or NH series) and the integrated control type (MSX, MAPPS, or Fanuc).

He pulled up the on the MAPPS IV panel. It wasn't just a list; it was a confession. The list was divided into sections: EX 1000s for tool management, EX 2000s for hydraulics, EX 3000s for safety interlocks. The problem was, the manual’s description for EX 1047 was frustratingly vague: "Abnormal load on magazine servo. Check physical interference and servo parameters."

Look up the specific X-address (Inputs) or Y-address (Outputs) related to the faulted component in your Mori Seiki Electrical Schematic Manual.

: A startup safety check requiring you to cycle the door once to verify the safety circuit. Spindle & Gearbox Alarms The Ultimate Mori Seiki EX Alarm List Guide:

While the core logic remains, the user interface and some alarm messages have evolved with the company. Original machines (pre-2010s) often use the MAPPS interface with Fanuc controls and have the alarm structure documented here. DMG MORI machines use more advanced interfaces like CELOS, but they still generate EX alarms from the underlying PLC logic. When troubleshooting, focus on the EX code itself; the fundamental problem (low hydraulic pressure, door interlock fault, etc.) is often the same regardless of the machine's generation.

: Attempted cycle start during tailstock movement or with the quill in the wrong position. EX0069 - Door Lock Check Time Over

Check the way-lube oil reservoir level. Inspect the lines for physical cracks or leaks. Ensure the pressure switch on the lube pump assembly is functioning. EX0194 / EX194: Chuck Unclamped / Clamp Error EX0170 - Lube Pressure Down / Way Lube

Verify your lubricant levels and check for leaks in the air lines. Interlock Key Switch Release

The oil reservoir for the slideways or spindle bearings is empty.

The thermal relay for the chip conveyor motor has tripped.
