    What to do if the Mitsubishi Electric Inverter option unit does not function?
    • V
      Valerie OwensAug 15, 2025
      If the option unit of your Mitsubishi Electric Inverter isn't working, try these steps: * Ensure the option is correctly fitted. * Reset the inverter. * Perform a complete parameter reset to return to initial values, then power the inverter on again. If you're using a network, check that: * Network cables between nodes are properly connected and terminated. * Network settings are correct using the Profibus-DP Network Configuration Software. * Other nodes aren't showing network errors. * The Profibus-DP master is properly connected and functioning.

    What to do if Mitsubishi Electric FR-E720-0.1K Inverter has overcurrent trip during constant speed?
    • K
      Kevin BushAug 21, 2025
      If your Mitsubishi Electric Inverter is experiencing an overcurrent trip during constant speed operation, it indicates that an overcurrent has occurred. To address this: * Ensure the load is stable. * Inspect the wiring for any output short circuits or ground faults. * Lower the stall prevention operation level. * Activate the stall prevention operation and the fast-response current limit operation (Pr.156). * If the motor is coasting, bring it to a stop before sending a start command. Alternatively, you can use the automatic restart after instantaneous power failure/flying start function.

    How to resolve overcurrent trip during deceleration or stop on Mitsubishi Electric FR-E720-0.1K Inverter?
    • V
      vickie58Aug 25, 2025
      If the Mitsubishi Electric Inverter experiences an overcurrent trip during deceleration or stop, it signifies that an overcurrent has occurred during these phases. Here’s what you can do: * Increase the deceleration time. * Check the wiring for output short circuits or ground faults. * Verify that the mechanical brake isn't activating too early. * Lower the stall prevention operation level. * Activate the stall prevention operation and the fast-response current limit operation (Pr.156). * If the motor is coasting, stop it before issuing a start command. Alternatively, use the automatic restart after instantaneous power failure/flying start function.

    How to fix regenerative overvoltage trip during deceleration or stop on Mitsubishi Electric Inverter?
    • M
      Mr. Daniel CruzAug 27, 2025
      If your Mitsubishi Electric Inverter is tripping due to regenerative overvoltage during deceleration or stop, it means overvoltage has occurred. Try these solutions: * Increase the deceleration time to match the load's moment of inertia. * Make the brake cycle longer. * Use the regeneration avoidance function (Pr. 882, Pr. 883, Pr.885, Pr.886). * Consider using a brake resistor, brake unit, or power regeneration common converter (FR-CV) as needed.

    How to resolve regenerative overvoltage trip during acceleration on Mitsubishi Electric FR-E720-0.1K Inverter?
    • M
      Monica WebbAug 30, 2025
      If your Mitsubishi Electric Inverter is tripping due to regenerative overvoltage during acceleration, it means overvoltage has occurred during acceleration. Here are some steps to take: * Decrease the acceleration time. * Implement the regeneration avoidance function using parameters Pr. 882, Pr. 883, Pr.885, and Pr. 886. * Ensure that the stall prevention operation level (Pr. 22) is set correctly.

    What to do if Mitsubishi Electric FR-E720-0.1K shows inverter overload trip?
    • D
      daniel91Sep 2, 2025
      If the Mitsubishi Electric Inverter experiences an overload trip (electronic thermal O/L relay function), it signifies that the electronic thermal relay function for inverter element protection has been activated. To address this: * Increase the acceleration time. * Adjust the torque boost setting (Pr. 0). * Configure the load pattern selection setting (Pr. 14) according to the machine's load pattern. * Reduce the load. * Ensure the surrounding air temperature is within specified limits.

    What to do if Mitsubishi Electric FR-E720-0.1K Inverter heatsink overheat?
    • H
      haasmarthaSep 5, 2025
      If your Mitsubishi Electric Inverter's heatsink is overheating, it indicates that the heatsink temperature is too high. To address this: * Ensure the surrounding air temperature is within the specified limits. * Clean the heatsink to remove any dust or obstructions. * Replace the cooling fan if it is not functioning correctly.

    Why does Mitsubishi Electric Inverter show input phase loss?
    • A
      Andrew BakerSep 8, 2025
      If the Mitsubishi Electric Inverter is indicating an input phase loss, it means one of the three input phases is missing or the phase-to-phase voltage is significantly unbalanced. To resolve this: * Ensure all cables are correctly wired. * Repair any breaks in the cable. * Check the input phase loss protection setting (Pr. 872). If the three-phase input voltage is largely unbalanced, set Pr. 872 to '0' to disable input phase loss protection.

    What causes stall prevention stop on Mitsubishi Electric FR-E720-0.1K Inverter?
    • A
      Angela JonesSep 12, 2025
      If the Mitsubishi Electric Inverter has a stall prevention stop, it means the output frequency has decreased to 1Hz because of deceleration caused by excessive motor load. To fix this, reduce the load and check the stall prevention operation level setting (Pr. 22).

    How to fix overcurrent trip during acceleration on Mitsubishi Electric FR-E720-0.1K Inverter?
    • S
      Scott AlvarezNov 17, 2025
      If the Mitsubishi Electric Inverter experiences an overcurrent trip during acceleration, it means that an overcurrent has occurred. To resolve this, try the following: * Increase the acceleration time. * Check for output short circuits or ground faults in the wiring. * If 'E.OC1' appears consistently at start, disconnect and restart the inverter. If the problem persists, the inverter may be faulty and you should contact your sales representative. * Ensure the base frequency is correctly set (Pr. 3) for your motor (50Hz). * Reduce the stall prevention operation level and activate both stall prevention and fast-response current limit operations (Pr.156). * For regenerative driving, adjust the base voltage in Pr. 19. * If the motor is coasting, stop it before issuing a start co...
