What to do if hpmont HD20 motor is overload?
If the motor connected to your hpmont Inverter is overloaded, adjust the setting of the V/f curve (F09.00 - F09.06). Check the power input to ensure it is adequate. If the motor needs to operate for a long time with a heavy load, use a special motor designed for such conditions. Also, check the load and mechanical transmission devices for any issues.
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 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.
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 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.
