KUKA Robot Controller
System · Basic
KUKA Robot KRC0579 - Max. triggers (50) defined
This alarm indicates that the maximum allowable number of 50 Trigger commands has been reached in the current KRC program or motion task. The KUKA KRC controller has a hard limit on the number of trigger definitions that can be simultaneously active, and this limit has been exceeded. This typically occurs when attempting to add additional trigger events beyond the system's capacity.

Max. triggers (50) defined
This alarm indicates that the maximum allowable number of 50 Trigger commands has been reached in the current KRC program or motion task. The KUKA KRC controller has a hard limit on the number of trigger definitions that can be simultaneously active, and this limit has been exceeded. This typically occurs when attempting to add additional trigger events beyond the system's capacity.
Common Causes
- Program contains more than 50 TRIGGER() function calls or trigger definitions
- Multiple trigger commands accumulated from modular program structure or subroutine calls
- Trigger events not properly cleared or deactivated after execution
- Nested or recursive program logic creating duplicate trigger instances
- Integration of multiple program modules each containing trigger definitions exceeding combined limit
Troubleshooting Steps
- 1Review the KRC program source code and count all TRIGGER() commands and trigger event definitions
- 2Consolidate redundant trigger definitions by combining multiple triggers into single trigger handlers where functionally appropriate
- 3Implement conditional trigger logic to activate only necessary triggers during specific program phases rather than defining all triggers at initialization
- 4Use UNTRIGGER() or equivalent deactivation commands to explicitly remove trigger definitions that are no longer needed
- 5Refactor program architecture to reduce modular dependencies and eliminate duplicate trigger definitions across subroutines
- 6Verify trigger cleanup procedures execute properly at program termination and reset the trigger counter before restarting execution
