The main pneumatic supply inlet pressure has dropped below the minimum requirement (typically ~0.5 MPa).
The machine never threw an EX 1047 again. But more importantly, the operators learned that the EX Alarm List wasn't a curse. It was a conversation. And if you ignored it long enough, the machine would have the last word.

Wipe down door interlock channels and chuck proximity sensors to prevent chip buildup. mori seiki ex alarm list
This was the genius of the Mori Seiki system. It wasn't just a list of emergencies; it was a story of neglect. The clogged filter had caused higher back-pressure. The higher pressure had starved the hydraulic unclamping mechanism, making the drawbar grip a tool holder just a little too tightly. When the tool changer tried to pull that holder from position 173, the servo had to fight. It won the fight, but the jarring motion had dislodged the ceramic chip that had been resting on top of the holder. The chip fell into the chain guide, and the next tool change caused the EX 1047.

While it requires the user to understand the difference between the Fanuc control brain and the Mori Seiki machine body, once that concept is grasped, the list is incredibly effective. It reduces downtime significantly compared to machines that provide vague error messages.
These are defined by Mori Seiki. They monitor things like door interlocks, hydraulic pressure, coolant levels, chuck status, and bar feeder sync.
Top off the coolant tank with water and soluble oil mixture. Clean any chips accumulated around the float switch that might keep it stuck down. EX0300 to EX0499: Chuck, Tailstock, and Fixturing Alarms It was a conversation
: Alarms like EX0557 (Lubricant) or EX2595 (Filter) are often simple maintenance reminders. Before calling a tech, verify oil levels and clean your filters .
A: You must first follow your machine's "disaster recovery" or "emergency recovery" procedure. This almost always involves referencing specific axes to their home positions, re-establishing the tool magazine status, and confirming the tool changer arm and pallet changer positions. Attempting to just reset and restart will often create mechanical collisions.
The machine detects that the operator door or a parts catcher/chute safety switch is open during automatic operation.
