PROGRAM SIZE OVER

What does ER02 mean?

This Fanuc Series 0i-D/0i Mate-D PMC alarm indicates that the sequence program (ladder program) is too large, exceeding the available memory for PMC operation. This makes the program invalid.

• The size of the sequence program exceeds the PMC's available memory capacity.
• The ladder step count option installed is insufficient for the program's size.
• Inefficient programming leading to an unnecessarily large program.

Click steps to track your progress.

1. 1

   Review the sequence program and identify opportunities to simplify logic or remove redundant code to reduce its overall size.

2. 2

   Consolidate subprograms or macros to optimize memory usage where possible.

3. 3

   Verify the current PMC memory configuration and compare it against the program's requirements.

4. 4

   Confirm the specified ladder step count option matches the actual capacity of the PMC.

5. 5

   If further program reduction is not possible, contact FANUC support for guidance on obtaining a larger ladder step count option.
