Memory error

What does 4001 mean?

The ring-0 memory management system is unable to provide the required memory resources for NC operations. This is typically a secondary symptom of another underlying issue, leading to the controller halting normal operation or experiencing critical failures due to insufficient memory.

• Defective or unstable RAM module on the NC controller board.
• Memory leak within a specific NC software module or application (e.g., an active user program).
• Exceeded memory capacity due to too many active processes, large data buffers, or extensive PLC data tables.
• Hardware fault in the memory controller or data bus pathways on the NC mainboard.
• Incorrectly configured memory allocation parameters (e.g., P8-05 'BufferCacheSize') leading to resource exhaustion.

Click steps to track your progress.

1. 1

   1. Perform a full power cycle of the NC controller to clear temporary memory states and reinitialize.

2. 2

   2. Check NC controller diagnostic logs for memory usage statistics and specific module-related memory errors.

3. 3

   3. If applicable, reseat or swap installed RAM modules with known good ones to verify hardware integrity.

4. 4

   4. Reduce the number of active NC programs or decrease data buffer sizes (e.g., adjust parameter P8-05).

5. 5

   5. Update the NC firmware to the latest stable version to resolve potential memory leak bugs or management issues.

6. 6

   6. Run manufacturer-specific memory diagnostic tools if available through the NC service interface.
