    What to do if my hpmont Inverter output shows overcurrent during acceleration?

      If your hpmont Inverter shows an overcurrent error during acceleration, it could be due to several reasons. Check the connection between the inverter and the motor to ensure it's properly connected. Verify that the motor parameters (F08.00 - F08.04) are correctly set. The inverter may be too small for the application, so consider selecting an inverter with a higher rating. The acceleration/deceleration time might be too short; adjust the Acc/Dec time (F03.01 - F03.04). Finally, if you are using vector control mode, perform parameter auto-tuning (F08.06).

    Why is my hpmont Inverter showing DC bus over voltage during acceleration?

      If your hpmont Inverter displays a DC bus over voltage error during acceleration, it could be due to a few reasons. First, check the input voltage to ensure it is not too high. Second, the deceleration time might be too short; set a proper Dec time (F03.02, F03.04). Also, improper wiring can lead to overvoltage, so check the wiring and ensure the inverter is wired correctly.

    How to troubleshoot DC bus undervoltage on hpmont Inverter?
    • J
      james40Sep 1, 2025
      A DC bus undervoltage on your hpmont Inverter can occur for a few reasons. At the beginning of powering on and the end of powering off, it is normal. However, if it occurs during operation, check if the input voltage is too low and ensure that the wiring is correct.
