How to reset Fuji Electric Controller password protection (inverter lock)?
- F
  Frank BassAug 25, 2025
  To reset the password protection (inverter lock) on your Fuji Electric Controller, you can: * Delete the password setting. Delete the password with the all clear command (PRG >5 > 2 >10). Note that when doing so, all inverter settings will also be initialized simultaneously. Then, reset the password. * To clear the Lok alarm while retaining the inverter settings, notify Fuji Electric and append the clear application number (PRG > 5 > 8). Fuji Electric will ensure that no illegal operations have been performed, and then issue an alarm clear code.

How do I troubleshoot a Fuji Electric Controller external alarm?
- K
  Kimberly RivasSep 10, 2025
  To troubleshoot an external alarm on your Fuji Electric Controller: * Check the operation of external equipment and remove the cause of the alarm that occurred. * Ensure that the external alarm signal wiring is correctly connected to the terminal to which the "Enable external alarm trip" terminal command THR has been assigned (Any of E01 through E07, E98, and E99 should be set to "9."). Connect the external alarm signal wire correctly. * Verify that the "Enable external alarm trip" terminal command THR has not been assigned to an unavailable terminal (with E01 through E07, E98, or E99). Correct the assignment if necessary.

- H
  harriskevinSep 17, 2025
  To resolve an enable circuit error on your Fuji Electric Controller: * Check whether the interface board is securely attached to the unit. The alarm will be cleared by turning ON the power again. * Check whether outputs from safety switches and so on are input to both terminals EN1 and EN2 with the same logic (High/High or Low/Low). The alarm will be cleared by turning ON the power again. * If unable to clear the error with the above procedures, the inverter condition is abnormal.
