Mori Seiki Ex Alarm List -
: Door interlock or door lock check time over.
For detailed lists and diagnostic procedures, refer to these professional documentation sources:
Turret indexes must be perfectly precise. Any misalignment triggers an external alarm.
The high-pressure coolant system cannot reach or maintain the required pressure.
Mori Seiki CNC machines are known worldwide for their rigid construction and precise engineering. However, when an external or machine-side error occurs, the control panel displays an . Unlike internal NC alarms (which relate directly to the Fanuc or Mitsubishi control system), EX alarms are defined by the machine tool builder (Mori Seiki) and relate to the machine's physical components, sensors, switches, and peripheral systems. mori seiki ex alarm list
The hydraulic unit pressure has dropped below the safe operating threshold. Check the hydraulic oil level, the pressure gauge, and the pressure switch functionality.
The oil reservoir for the slideways or spindle bearings is empty.
Clean the safety switch assembly. Replace the door interlock switch if internal contacts are failing. 4. Chuck, Tailstock, and Fixture Alarms (EX0600 - EX0799)
While (like Fanuc system alarms) relate to the core controller, EX alarms (External Alarms) are defined by the machine tool builder (Mori Seiki). These alarms indicate issues with peripheral hardware, safety interlocks, fluid levels, pneumatic pressure, or the tool changer. : Door interlock or door lock check time over
Check hydraulic pressure settings and inspect hoses for leaks or bubbles. Filters & Fans
These codes typically trigger when the machine's safety guard system detects an unsafe operating condition.
Fix: Clean chips and coolant away from the door switch. Check if the key actuator on the door is aligned properly with the switch block.
Look closely at the alarm screen. Mori Seiki MAPPS controls often provide a short descriptive sentence beneath the EX code. Note the exact wording. Step 2: Check the Physical Prerequisites The high-pressure coolant system cannot reach or maintain
Refill the way lube tank immediately. If full, check for a broken lube line causing a pressure leak, or a faulty pressure switch. EX0201 - Coolant Level Low
These errors ensure that workholding is secure before the spindle spins or axes move.
EX alarms stand for . They indicate that the CNC control itself is working fine, but an external condition required for safe operation has not been met. These alarms are programmed by Mori Seiki via the ladder logic to protect the operator, the workpiece, and the machine components.
Mori Seiki machine "EX" alarms generally refer to (Machine Alarms) defined by Mori Seiki rather than the standard NC alarms provided by the control manufacturer like Fanuc . These codes typically signal issues with peripheral machine functions such as sensors, door interlocks, hydraulics, and tool changers. Common EX Alarm Categories
