KUKA Robot KRC0181 - GENERAL ERROR: <error no.> <function> <additional info>

GENERAL ERROR: <error no.> <function> <additional info>

KRC0181 indicates that the robot controller received an unexpected or unrecognized feedback response from a function call within the object-oriented program structure. This occurs when a called function returns a value or status that does not match the expected data type, range, or format defined in the program logic, causing the controller's interpreter to fail validation of the function's output.

Common Causes

  • Function return value does not match the declared data type in the function signature
  • Corrupted or incomplete data transmission from a called subroutine or library function
  • Incompatible software versions between the main program and called function modules
  • Memory corruption or stack overflow affecting function return pointer or output variable
  • Incorrect parameter passing or uninitialized variables being returned from the function call

Troubleshooting Steps

  1. 1Review the program log files and enable detailed error logging to identify which specific function triggered the alarm and what unexpected feedback was received
  2. 2Verify that all function return types match their declarations in the program source code and that no type casting errors exist
  3. 3Check for software consistency across all loaded programs and libraries; reload or recompile the main program and all called functions from source
  4. 4Perform a controller memory test using the Diagnostics menu to detect potential memory corruption or DRAM failures
  5. 5Validate all function parameters at the point of call and ensure no variables contain undefined or out-of-range values before function execution
  6. 6If the error persists, perform a complete controller backup, restore to factory defaults, and reload the application program from a verified source file
