KUKA Robot KRC0180 - SYNTAX ERROR IN FILE <filename> IN ROW <contents of the line>

SYNTAX ERROR IN FILE <filename> IN ROW <contents of the line>

This alarm indicates a syntax error was detected while the KRC controller parsed a parameter file during initialization. The controller identified invalid syntax, incorrect formatting, or malformed commands in the specified line of the configuration file, which prevents proper interpretation of robot parameters such as axis limits, tool data, or kinematic settings.

Common Causes

  • Incorrect parameter syntax or missing required delimiters (colons, semicolons, brackets)
  • Invalid data type for parameter value (e.g., text string where numeric value expected)
  • Mismatched or unclosed brackets, parentheses, or quotation marks in the file
  • Obsolete or deprecated parameter names incompatible with current KRC software version
  • Special characters, tabs, or non-ASCII characters in parameter definitions

Troubleshooting Steps

  1. 1Open the referenced parameter file in a text editor and navigate to the specified row number
  2. 2Verify the syntax of the flagged line against the KUKA KRC parameter documentation for correct format and data types
  3. 3Check for missing or extra delimiters (colons, semicolons, commas) and ensure proper bracket/parenthesis pairing
  4. 4Remove any special characters, tabs, or non-ASCII text that may corrupt the parser
  5. 5Compare the syntax with a known working parameter file template or backup to identify deviations
  6. 6Save the corrected file in plain text format (UTF-8 encoding without BOM) and reload the parameters via the KRC teach pendant or WorkVisual interface
