Moisture in air lines damages pneumatic valves, leading directly to frequent air pressure drops and slow ATC cycles. Ensure your shop air dryer is serviced regularly.
Check if the lube reservoir is completely empty. If full, check for physical leaks in the plastic lines tracking along the axes. Inspect the pressure switch on the lube pump assembly or look for a blocked metering valve. EX0152 / EX152: Hydraulic Pressure Decline
The coolant tank level has dropped below the minimum sensor threshold. EX0451 (Spindle Lube Alarm):
Among the various alarm classifications, are unique. Unlike system or servo alarms that originate deep within the CNC control software or drives, EX alarms are generated by the machine's Programmable Logic Controller (PLC) or ladder logic. They generally point to issues with peripheral hardware, safety interlocks, fluid levels, or mechanical limits. mori seiki ex alarm list
Open your Fanuc or Mitsubishi control screen to view current I/O bit states: Press the key. Select the PMC softkey, then choose DIAGNOSIS or STATUS .
Alarm: 3001 / OVER TRAVEL (LIMIT)
If you want, I can:
Check the hydraulic solenoid valve operating the turret clamp/unclamp. Verify the unclamp proximity switch is functioning. EX1201: ATC Magazine Arm Fault
Here are a few examples of common alarms found on the Mori Seiki EX alarm list:
NC alarms are usually related to software or control data, but . They alert you to a real-world problem detected by a sensor, limit switch, or other physical component like a door lock, a hydraulic pump, or a gearshift mechanism. Moisture in air lines damages pneumatic valves, leading
– The spindle failed to orient or index within the allotted time.
The machine door is open while trying to execute a cycle, or the interlock switch is not engaging.
The turret took too long to rotate to the next tool station or failed to hydraulically re-seat and clamp back down tightly onto the curvic coupling. If full, check for physical leaks in the
