- 1
1. Record the exact internal sub-code (e.g., 1025) that accompanies the main fault, as this is crucial for advanced diagnostics.
- 2
2. Execute a full power cycle of the drive by removing main input power for at least 60 seconds before re-energizing.
- 3
3. Attempt to clear the fault via the drive's LCP (e.g., using the reset button or P16-90 menu).
- 4
4. Update the drive's main firmware to the latest available version if a known bug fix for this fault range exists.
- 5
5. Check all internal cable connections within the drive (e.g., between control board and power board) for secure seating and absence of damage.
