Mori Seiki Ex Alarm List Jun 2026

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

The coolant volume in the main reservoir tank has dropped below the safe operating float switch level.

The way-lube system failed to build sufficient pressure during its scheduled pump cycle.

Understanding this distinction is critical for shop floor diagnostics. Treating an external PMC lock like an internal software glitch leads to unnecessary downtime, whereas referencing a dedicated enables operators to pinpoint the exact failing switch or fluid drop.

Check if the lube reservoir is completely empty. If full, check for physical leaks in the plastic lines tracking along the axes. Inspect the pressure switch on the lube pump assembly or look for a blocked metering valve. EX0152 / EX152: Hydraulic Pressure Decline

A massive percentage of daily EX alarms are caused by simple fluid maintenance neglect or pressure drops. Check:

Alarm: 1011 / OVERLOAD (SPINDLE/SERVO)

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.

Do not just look at the number. Read the short text next to the EX code on the screen. It often tells you exactly which part of the machine is sad. 2. Check the Ladder Diagram

Generated by the CNC core itself (e.g., servo errors, memory errors, or G-code syntax mistakes). Core control or drive errors (e

Since EX alarms are PLC-based, they are often triggered by a limit switch, proximity sensor, or pressure switch.

Mori Seiki (now DMG MORI) machines, particularly those in the EX series, are known for their robust design and precision. However, when an "EX" alarm appears, it can halt production. Unlike Fanuc system alarms (like 401 or 414), EX alarms are , often indicating a machine-specific issue (PLC/Ladder logic) rather than a pure CNC servo fault.

The chip conveyor belt is jammed, causing the motor thermal relay to trip. Understanding this distinction is critical for shop floor

The chip conveyor motor drew too much current, indicating a mechanical jam.

1. Turn off the conveyor power.2. Manually clear any jammed parts, stringy chips, or debris.3. Reset the thermal overload switch inside the electrical cabinet. AIR PRESSURE DROP
