    What to do if the NS LED lights in red on Fuji Electric FRENIC-Multi OPC-E1-DEV Control Unit (er5 alarm cannot be reset)?
    • J
      John JacksonAug 1, 2025
      If the NS LED lights up red and the er5 alarm cannot be reset on your Fuji Electric Control Unit, the issue might stem from several causes. First, ensure the node address is unique to prevent conflicts in DeviceNet. Next, verify that the baud rate settings match. Also, confirm that the 24 V power supply is correctly connected. Inspect the DeviceNet cabling for any issues and correct them. Finally, power cycle both the inverter and the option after making any DIP switch modifications.

      If the NS LED is blinking red on your Fuji Electric Control Unit and the er5 alarm has occurred, it could be due to a broken cable during communication. In this case, repair or replace the broken cable. Another potential cause is that the I/O scan interval is too short. Try increasing the I/O scan interval to resolve the issue.

      Anita JohnsonAug 9, 2025
      If none of the LEDs on the Fuji Electric Control Unit option are lighting up, the problem may be due to a disconnected 24 VDC power supply. Check to ensure that a 24 VDC power supply is properly connected. If the power supply is connected and the LEDs still don't light, the option itself might be faulty and need replacement.

      Curtis AlvaradoAug 14, 2025
      If the NS LED is not lighting up on your Fuji Electric Control Unit, it could be due to an improper node address setting for the option. Correct the node address for the option. Another potential cause is a broken cable for DeviceNet communications. Repair or replace the broken DeviceNet communication cable.

    What to do if er4 alarm cannot be reset on Fuji Electric FRENIC-Multi OPC-E1-DEV (The MS LED lights in red)?
    • M
      Matthew MercerAug 17, 2025
      If the er4 alarm cannot be reset and the MS LED is red on your Fuji Electric Control Unit, the option might not be properly mounted. Ensure that the option is correctly mounted. Another possible cause is that the option connection cable is not connected. Connect the option connection cable. If the problem persists, the option might be faulty and require replacement.

    Why the NS LED keeps blinking in green and does not stay on in green on Fuji Electric FRENIC-Multi OPC-E1-DEV Control Unit?
    • I
      icortezAug 23, 2025
      If the NS LED keeps blinking green and does not stay on green on your Fuji Electric Control Unit, it could be because the master is not requesting a connection. Ensure the master requests a connection. The I/O scan interval might also be set too short at the start of communication; set a longer I/O scan interval. Additionally, the I/O area might be invalidly mapped; correct the I/O area mapping. Finally, there might be no I/O connection; establish the I/O connection.

    What to do if the settings for run command or speed command cannot be validated even though the NS LED lights in green on Fuji Electric Control Unit?
    • D
      Diana PorterAug 27, 2025
      If the settings for the run command or speed command cannot be validated even though the NS LED lights in green on your Fuji Electric Control Unit, verify that either NetCtrl or NetRef is set to "1." Also, check if a higher-priority run command or speed command is enabled on the inverter and disable it. Ensure that the selection of I/O Assembly Instances is correct. Finally, power OFF and then ON the inverter and the option after modifying the o31 data.
