KRC0854

KUKA Robot KRC0854 - INITIAL BLOCK NUMBER > FINAL BLOCK NUMBER 2190

INITIAL BLOCK NUMBER > FINAL BLOCK NUMBER 2190

This alarm indicates that the initial block number specified in a KRL program is greater than the final block number, which is a logical impossibility. The program execution cannot proceed because the block range definition is inverted or invalid, preventing proper program flow control.

Common Causes

  • Incorrect block number parameters entered in program initialization
  • Swapped or reversed initial and final block number values
  • Manual editing error when defining block number ranges in KRL code
  • Corrupted or malformed block number configuration in the program source
  • Copy-paste error resulting in duplicate or inverted block number assignment

Troubleshooting Steps

  1. 1Verify the initial and final block numbers in the KRL program source code are correctly ordered
  2. 2Confirm that the initial block number is less than or equal to the final block number
  3. 3Review the program file for recent edits or manual modifications to block number definitions
  4. 4Check the KRL syntax around the block number declaration for formatting errors
  5. 5Reload or recompile the program after correcting the block number parameters
  6. 6If the error persists, restore the program from a known good backup and re-apply any necessary modifications
