  • Ensure qualified technician performs repairs

Causes and Fixes

  1. 1

    SAFETY: Stop all machine operations

    Ensure machine is in safe state before proceeding with diagnostics.

  2. 2

    Check coordinate system programming

    Review G-code for coordinate system calls (G54-G59) and verify syntax and values are within machine limits.

  3. 3

    Verify coordinate values

    Ensure all coordinate system offset values are within the machine's travel limits and properly formatted.

  4. 4

    Reset and test carefully

    Clear alarm, verify machine position, and test program in single block mode.

Service Recommendedmedium confidence

Call a technician if:

  • ·If alarm involves coordinate system memory corruption
  • ·If machine positioning accuracy is affected
  • ·If alarm persists after program correction
  • ·When system-level memory reset is required

Prevention

  • Validate programs using simulation before execution
  • Ensure G-code matches the control's capabilities

Common Mistakes

  • Overlooking the specific block number in the alarm
  • Assuming hardware fault instead of program error
