– The turret failed to complete its rotation within the allotted time; often caused by mechanical obstruction or sensor failure. EX0374/0375: Tool Life Up – Pre-set tool life count has reached its limit. Spindle & Motor Alarms Spindle Drive Unit Alarm – A fault has occurred in the spindle amplifier or drive. Spindle Orientation Time Up

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.
The "mori seiki ex alarm list" is not a single document but a concept encompassing the sophisticated, machine-specific logic that makes these tools reliable and productive. When an EX alarm appears, it is the machine communicating that a critical mechanical or electrical condition has been met.
– Indicates a fault within the spindle amplifier or drive circuitry. When an EX alarm halts your production, follow
These errors relate to peripheral management, including chips, coolant, and temperature controls.
If the message is vague, look at the Diagnostic (DGNOS) bits. Mori Seiki manuals often list specific bits that trigger these alarms.

When an EX alarm appears, do not panic. A systematic approach will usually lead you to the root cause. Follow this general workflow:
To appreciate the EX Alarm List, one must first distinguish it from standard system alarms. A system alarm, often displayed as a numeric code (e.g., 1020, 2001), originates directly from the CNC controller (typically a Fanuc, Mitsubishi, or Siemens unit) and indicates a problem with the core control logic—such as an overloaded servo, a broken encoder, or a loss of reference position. These alarms are generic across many machine brands using the same controller.
A well-structured EX list will also provide a and recommended action for each code. For instance, an entry might read:
