Internal fault

Hva betyr 38 ?

A general unspecific internal fault has occurred within the drive. This indicates a hardware or software malfunction that prevents normal operation and requires further investigation to determine the root cause, as it's a catch-all for various internal issues.

• Transient software error or firmware corruption within the drive's control board.
• Malfunction of internal hardware components such as a power supply, communication bus, or memory module.
• Electrical noise or electromagnetic interference (EMI) disrupting sensitive internal control circuits.
• Internal sensor failure (e.g., current sensor, voltage sensor) providing erroneous data to the control logic.
• Defective PCB (Printed Circuit Board) component or manufacturing defect leading to intermittent operation.

1. 1

   Record the exact fault code and any sub-code or additional diagnostic information displayed on the LCP.

2. 2

   Power cycle the drive by safely disconnecting and reconnecting the main power supply (after waiting for DC bus discharge).

3. 3

   Verify the integrity of the drive's ground connection (PE terminal) and ensure proper shielding for all control cables.

4. 4

   Check for any recent firmware updates or parameter changes that might have triggered the fault, revert if necessary.

5. 5

   If the fault persists after power cycling and ground verification, replace the drive as it indicates an unrecoverable internal hardware or software issue.
