What causes KUKA Robot alarm KRC1026?

Program contains too many nested or sequential local function definitions within a single module. Excessive code generation or macro expansion creating numerous subroutines automatically. Poor program structure with all subroutines defined locally instead of distributed across multiple files. Legacy code migration or consolidation combining multiple programs into one object. Automatic code generation tools producing redundant local subroutine declarations.

How do I fix KUKA Robot alarm KRC1026?

1. Review the program structure and identify all local subroutine declarations using the KRL editor outline view 2. Refactor the code by splitting the oversized object into multiple smaller modules or program files 3. Move non-essential local subroutines to separate library files to reduce the count in the main object 4. Consolidate similar or redundant subroutines to eliminate duplicate local function definitions 5. Use external function libraries instead of defining all subroutines locally within the object 6. Recompile the program after restructuring and verify the subroutine count remains below the 2711 limit

Alarm KRC1026

KUKA Robot KRC1026 - <object name> TOO MANY LOCAL SUBROUTINES 2711

This alarm indicates that a KRL program object has exceeded the maximum allowed number of local subroutines, which is limited to 2711 per object. The compiler cannot process the program because it violates KUKA's internal structural constraints for subroutine organization.
