Mori Seiki Ex Alarm List

The vast majority of EX alarms are entirely preventable. Implement these regular maintenance routines to keep your Mori Seiki running smoothly:

Inspect hydraulic hoses for bubbles or leaks. Verify that all electrical cabinet fans are spinning and filters are free of oily dust. To help narrow down the issue, let me know: What is the exact EX alarm number and text on your screen?

Usually caused by a "rat's nest" of chips jamming the belt. Reverse the belt to clear. Door Interlock

– A general fault detected within the hydraulic system. 2. Extended EX Alarm List Reference

These alarms often relate to configuration, data loss, or specific machine modes. mori seiki ex alarm list

Check the electrical cabinet for tripped thermal overloads or circuit breakers (especially common for conveyor or coolant pump errors).

Below is a categorized table of common EX alarms compiled from machine manuals and real-world service reports. Note that while these interpretations are widely applicable, some codes can have machine-specific meanings. Always prioritize your machine's official ladder documentation.

Turret indexing and tool changing require precise mechanical and electrical synchronization.

Maintain way lube, hydraulic oil, and spindle chiller fluids at maximum levels rather than waiting for the "low" threshold. The vast majority of EX alarms are entirely preventable

Do not just look at the flashing red light. Press the or [MESSAGE] key on your MAPPS/MSG control panel. Read the specific code and text. Many Mori Seiki machines provide a secondary status sub-code or bit indicator on this page that pinpoints the exact failed sensor. 2. Check Diagnostics (PC parameters)

They interface with the machine’s or PMC.

CNC machines are messy places full of metal chips and oil. Proximity sensors often get covered in metal dust. Wipe down sensors near the tool changer, chuck, and doors.

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 To help narrow down the issue, let me

: Safety and Operation Alarms (e.g., Door Open, Emergency Stop).

The thermal relay for the coolant pump has tripped. This happens if the pump impeller is jammed with chips or if the motor winding is failing. 2. Door Interlock and Safety Alarms
