Mori Seiki Ex Alarm List Here

EX alarms originate from the PLC (Programmable Logic Controller) ladder logic. They are not hardware failure alarms (those usually start with "SV", "SP", or "OH"). Instead, EX alarms are triggered by:

Each alarm is assigned a 4-digit number (e.g., EX0001 to EX1999) and a plain English message. The list varies slightly depending on the machine model, control version (MAPPS I, II, III, IV, Celos), and optional equipment.

Entry-level Dura series share simpler alarms:

The Mori Seiki EX series (now DMG MORI EX) are high-performance CNC turning centers known for rigidity, accuracy, and productivity in metalworking. The alarm (error) system on these machines provides numeric and sometimes alphanumeric codes that indicate faults in drives, spindle, axes, probes, I/O, PLC, servo, following errors, temperature, encoder issues, and safety/interlocks. Correct interpretation of alarms is critical for safe, fast troubleshooting and minimizing downtime.

No single article can list every EX alarm, because machine builders and integrators add custom alarms. To get the official and complete list: mori seiki ex alarm list

Since the EX series utilizes Fanuc controls (typically 16i/18i/21i or 0i-TD/TC), you will see standard Fanuc alarms.

Mori Seiki EX Alarms are machine-specific external errors triggered by the Programmable Machine Control (PMC) rather than the base Fanuc or Mitsubishi CNC system. These codes typically relate to physical machine hardware like doors, turrets, spindles, and safety interlocks. www.scribd.com Common EX Alarm Categories Safety & Interlocks : Issues with door locks, emergency stops, or safety tests.
