Clean the safety switch assembly. Replace the door interlock switch if internal contacts are failing. 4. Chuck, Tailstock, and Fixture Alarms (EX0600 - EX0799)
The automatic tool changer is a complex dance of mechanical and electronic coordination. Interruptions are common but usually resolvable.
Drain water traps daily. Clean dry air prevents the EX0105 Air Pressure Down fault and protects internal pneumatic solenoids.
This comprehensive guide breaks down the standard Mori Seiki EX alarm list, what these codes mean, and how to safely troubleshoot them to minimize your workshop's downtime. Understanding EX Alarms mori seiki ex alarm list
In the world of high-precision manufacturing, a CNC machine tool is far more than an assembly of motors, guides, and spindles; it is a complex, intelligent system capable of self-diagnosis. For operators and maintenance engineers of Mori Seiki (now DMG MORI) equipment, few tools are as vital as the . Far from a mere error catalog, this list represents the machine’s primary means of communicating its internal state, guiding users from the symptom of a sudden halt to the root cause of a malfunction. Understanding the structure, logic, and application of the EX Alarm List is not just a technical skill—it is fundamental to maximizing uptime, ensuring safety, and preserving the longevity of these sophisticated assets.
The automatic way-lube system failed to build up or vent pressure within the programmed time limit.
Do not just look at the blinking red light. Press the or [ALARM] hard key on your Mori Seiki control. Look for sub-text or second pages that display additional PMC diagnostic data. 2. Check the PMC Diagnostics (D-Bits and X-Bits) Clean the safety switch assembly
The main hydraulic unit pressure dropped below the safe operating limit (often required for chucking and tailstock movement).
The true value of the EX Alarm List emerges during unplanned downtime. Consider a scenario: A Mori Seiki NLX lathe suddenly stops mid-operation with the message “EX0315 COOLANT TANK LEVEL LOW.” Without the EX list, an operator might waste hours checking the CNC program, servo drives, or tool offsets. With the list, the diagnosis is immediate: either the coolant has evaporated, there is a leak, or the level sensor has failed. The machine has effectively diagnosed itself.
Minimising downtime requires proactive care of the systems that monitor these alarms. Chuck, Tailstock, and Fixture Alarms (EX0600 - EX0799)
Vacuum dust filters; ensure fans run smoothly to prevent overheating. Control Overheat Alarms If you want to isolate a specific error code, let me know: The on your screen
Check the HPU oil level. Look for a tripped circuit breaker for the hydraulic pump motor in the electrical cabinet. Replace the pressure switch if it fails to register valid pressure. EX0401 / EX401: Coolant Level Low
