To help find the exact fix for your machine, could you tell me:
Ensure a part is properly loaded. Adjust the proximity sensors on the back of the hydraulic actuator cylinder to properly read the stroke of the drawtube. EX0350 - Tailstock Barrier / Interlock Violation
EX0600 - EX0999: Turret, ATC (Tool Changer), and Chucking Alarms mori seiki ex alarm list
The turret failed to seat and clamp back down tightly onto its curvic coupling after indexing.
Never bypass an EX safety alarm (e.g., door interlock or chuck clamp confirmation) to save cycle time. They exist to protect both the operator and the multi-ton machine investment. When in doubt, call a certified DMG MORI service technician – but now, with this guide, you’ll know exactly which EX alarm to report. To help find the exact fix for your
Understanding these codes is essential for minimizing downtime and ensuring the safety of both the operator and the machine. 1. Common Mori Seiki EX Alarm Categories

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.
When an EX alarm halts your production, follow this step-by-step diagnostic workflow to identify the root cause quickly: Step 1: Analyze the Screen Text and Code Never bypass an EX safety alarm (e
The number following “EX” is key. Most Mori Seiki EX alarms use a 4-digit code (1000-3999 range), though older models may use 3-digit codes.
