Internal fault (Specific range)

Hva betyr 1379–2819 ?

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.

• Transient power supply instability on the internal 5VDC or 3.3VDC rails.
• Firmware corruption due to an interrupted update procedure or internal memory write error.
• Component degradation on the main control board (e.g., a failing electrolytic capacitor or integrated circuit).
• Overheating of internal processing units leading to calculation errors or unexpected behavior.
• Corrupted configuration data in non-volatile memory (EEPROM or Flash) that affects critical system startup.

1. 1

   Record the exact fault sub-code displayed on the Local Control Panel (LCP) for further analysis.

2. 2

   Power cycle the drive by disconnecting mains voltage (L1, L2, L3) for at least 60 seconds.

3. 3

   Verify the drive's internal cooling fan operation and clean any dust from internal heat sinks.

4. 4

   Measure the internal 24VDC, 5VDC, and 3.3VDC supply voltages on designated test points of the control board.

5. 5

   Attempt to re-upload the drive's firmware using the specified programming tool and the correct firmware version.

6. 6

   Backup drive parameters, then perform a factory reset via Parameter P14-22 (Reset options) set to 2 (Load LCP defaults).
