Internal fault (Specific range)

Hva betyr 1024–1284 ?

A general internal fault has occurred within a specific range of internal error codes. This indicates an unspecified internal hardware or software malfunction that requires specialized attention.

• Firmware execution error or software crash within a specific module of the drive's control system.
• Detection of an invalid memory address access or data corruption within the drive's RAM.
• Failure of an internal sensor or monitoring circuit (e.g., for voltage, current, temperature) that is not categorized as a standard fault.
• Intermittent communication bus failure between the main control board and power board components.
• Degradation or failure of a critical internal power supply rail (e.g., 5V, 3.3V) on the control board.

1. 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

   2. Execute a full power cycle of the drive by removing main input power for at least 60 seconds before re-energizing.

3. 3

   3. Attempt to clear the fault via the drive's LCP (e.g., using the reset button or P16-90 menu).

4. 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

   5. Check all internal cable connections within the drive (e.g., between control board and power board) for secure seating and absence of damage.
