What to do if hpmont HD20 Inverter has Fault of current detection circuit?
- DDonald RiceSep 23, 2025
If your hpmont Inverter indicates a fault in the current detection circuit, please contact the supplier for repairing.
What to do if hpmont HD20 Inverter has Fault of current detection circuit?
If your hpmont Inverter indicates a fault in the current detection circuit, please contact the supplier for repairing.
What to do if hpmont HD20 output has overcurrent in Acc process?
If your hpmont Inverter shows an output overcurrent during the acceleration process, it could be caused by several factors. Ensure the inverter and motor are properly connected. Verify and set the correct motor parameters using settings F08.00 to F08.04. If the problem persists, consider using an inverter with a higher power rating. Also, check and adjust the acceleration and deceleration times using parameters F03.01 to F03.08. If an instant stop occurs and the motor restarts, set the start mode to speed tracking by setting F02.00 to 2.
What to do if hpmont Inverter DC bus has over voltage in Acc process?
If the DC bus of your hpmont Inverter experiences overvoltage during acceleration, first check the power input to ensure it is not too high. Set a proper value for the deceleration time using parameters F03.02, F03.04, F03.06, and F03.08. Verify the wiring is correct. If an instant stop occurs and the motor restarts, set the start mode to speed tracking (F02.00 = 2). Also, ensure that the braking devices are selected according to the recommendations in the user manual.
What to do if hpmont HD20 Inverter output has fault of power module?
If your hpmont Inverter indicates a fault in the power module, check for a short circuit between the output phases or a short circuit to the ground. Ensure the wiring is properly connected and check for any issues with the connection and mechanism. If the output current is too high, inspect the connections. If the power module is damaged, please contact the supplier for repairing.
Why hpmont Inverter shows heatsink overheat?
If your hpmont Inverter's heatsink is overheating, it could be due to several reasons. The ambient temperature might be too high, or the inverter's external ventilation might be insufficient. Check for a fan fault or a fault in the temperature detection circuit. You can use an inverter with higher power capacity and improve ventilation around the inverter. If there is a fan fault, replace the cooling fan and if there is a fault occurs to temperature detection circuit, please seek technical support.
What to do if hpmont HD20 Inverter has PID reference loss?
If your hpmont Inverter experiences a PID reference loss, and the analogue reference signal is smaller than F20.12, check the connection. If the issue persists, please seek technical support.
What to do if hpmont HD20 Inverter has PID feedback out of limiting?
If the PID feedback on your hpmont Inverter is out of limiting, and the analogue setting signal is bigger than F20.16, check the connection. If the issue persists, please seek technical support.
What to do if hpmont HD20 has PID feedback loss?
If your hpmont Inverter experiences a PID feedback loss, and the analogue setting signal is smaller than F20.14, check the connection. If the issue persists, please seek technical support.
Why hpmont HD20 contactor is not actuated?
If the contactor in your hpmont Inverter is not actuating, it could be due to a contactor fault or a fault in the control circuit. Try replacing the contactor. If the issue persists, please seek technical support.
What to do if hpmont HD20 Inverter shows DC bus undervoltage?
If your hpmont Inverter indicates a DC bus undervoltage, note that this is normal when powering on and off. However, if it occurs during operation, check the input power voltage to ensure it is sufficient. Also, inspect the wiring and ensure the inverter is wired properly.
