Code 404: MEMORY CAPACITY EXCEEDED
Issue Description & Safety Warning
The Mazak Mazatrol Matrix CNC has triggered a critical MEMORY CAPACITY EXCEEDED alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Type of error: A — Operation (a wrong key was pressed or the machine was operated incorrectly) Stopped status: L — Operation continued Clearing procedure: S — Press clear key Display colour: Blue Cause: 1. Additional creation of a machining program is no longer possible since the memory has already been filled up to its machining-program data storage capacity. 2. Additional preparation of process control data is no longer possible since 100 sets of such data have already been stored. 3. Additional preparation of program layout data is no longer possible since 4000 sets of such data have already been stored. Action: Make an available storage area by either erasing an unnecessary machining program from the memory or saving a machining program onto an external storage, and then create a new machining program.
