Alarm KRC0161

KUKA Robot KRC0161 - *<command name> ACTIVE

This informational alarm indicates that the OBJH (Object Handle) command is currently being executed within the robot program. The OBJH command is used to manage object-oriented program elements and handle references to program objects in KUKA KRC systems. This is a status notification rather than an error condition, appearing when the controller is actively processing object handle operations.

KUKA Robot KRC0161 - *<command name> ACTIVE

*<command name> ACTIVE

This informational alarm indicates that the OBJH (Object Handle) command is currently being executed within the robot program. The OBJH command is used to manage object-oriented program elements and handle references to program objects in KUKA KRC systems. This is a status notification rather than an error condition, appearing when the controller is actively processing object handle operations.

Common Causes

  • Normal execution of OBJH command during program runtime
  • Object reference initialization or assignment in progress
  • Multiple OBJH commands executing sequentially in the program flow
  • Nested OBJH operations within conditional or loop structures
  • Synchronization of object handles across multiple program tasks

Troubleshooting Steps

  1. 1Verify that the OBJH command syntax is correct in the robot program source code
  2. 2Check that all referenced objects exist and are properly initialized before OBJH execution
  3. 3Review the program logic to ensure OBJH commands are executing in the intended sequence
  4. 4Monitor the teach pendant display to confirm expected program behavior during OBJH execution
  5. 5Verify that object scope and variable declarations are appropriate for the OBJH operation context
  6. 6If alarm persists abnormally, reset the program counter and restart execution from a known safe point
