What does fault of input phase mean on hpmont HD30-4T055G/075P Inverter?
If your hpmont three-phase input inverter shows a fault of input phase, it means a phase loss fault has occurred to the power input; check the three-phase power input. If this doesn't solve your problem, seek technical support.
Why is my hpmont HD30-4T055G/075P showing DC bus over voltage during acceleration?
DC bus over voltage during acceleration in your hpmont Inverter can occur due to several reasons. The input voltage might be too high, so check the power input. Also, the deceleration time could be too short; adjust it using parameters F03.02, F03.04, F03.06, and F03.08. Improper wiring can also lead to overvoltage, so inspect the wiring and ensure the inverter is wired correctly. If an instant stop occurred and the motor restarted, set the start mode to speed tracking (F02.00=2). Finally, ensure that the braking devices are properly selected according to the user manual's recommendations.
How to fix hpmont HD30-4T055G/075P Inverter output overcurrent during acceleration?
To resolve an hpmont Inverter output overcurrent during acceleration, consider these potential causes. Ensure proper connection between the inverter and the motor. Verify and correct motor parameters using F08.00, F08.04, F13.01, and F13.05. If the inverter's rating is too small, select one with a higher rating. Also, adjust the acceleration and deceleration times using parameters F03.01 and F03.08. If an instant stop occurs and the motor restarts, set the start mode to speed tracking (F02.00=2).
What causes a motor overload on my hpmont HD30-4T055G/075P Inverter?
A motor overload on your hpmont Inverter can stem from several causes. An improper setting of the V/f curve can be a factor, so adjust it using parameters F09.00-F09.06. Also, a low mains supply voltage can contribute, so check the power input. If the motor runs for a long time with a heavy load at low speed, consider using a special motor designed for such conditions. Ensure the motor’s overload protection factor is properly set. Finally, check for a blocked torque or an excessively heavy load, and inspect the load and mechanical transmission devices.
What to do if my hpmont Inverter shows DC bus undervoltage?
DC bus undervoltage on your hpmont Inverter can be caused by a few things. First, check the input power voltage to ensure it is not too low. If it is, correct it. Also, improper wiring can lead to undervoltage, so verify the wiring and ensure the inverter is wired correctly. Note that this can be a normal status during powering on and powering off.
What does access fault of control board EEPROM mean on hpmont Inverter?
An access fault of the control board EEPROM on your hpmont Inverter indicates a memory circuit fault of the control board EEPROM. Contact the supplier for repairing.
What to do if there is a fault of current detection circuit on hpmont HD30-4T055G/075P Inverter?
If there is a fault of the current detection circuit on your hpmont Inverter, indicating that the current detection circuit is damaged, contact the supplier for repair.
What does access fault of display panel EEPROM mean on hpmont Inverter?
An access fault of the display panel EEPROM on your hpmont Inverter indicates a memory circuit fault of the display panel EEPROM. You can try replacing the display panel. If the problem persists, contact the supplier for repairing.
What causes parameters auto-tuning fault on hpmont HD30-4T055G/075P?
A parameters auto-tuning fault on your hpmont Inverter can occur if the parameter auto-tuning times out, so check the motor’s connection. Ensure that you input the correct motor parameters (F08.00, F08.04, F13.01, F13.05). If problems persist, seek technical support.
Why am I getting a fault setting of parameters error on my hpmont HD30-4T055G/075P?
A fault in the parameter settings of your hpmont Inverter can occur if the power rating between the motor and inverter is too different; select an inverter with a suitable power rating. It can also be due to improper setting of motor parameters, so set the correct values for motor parameters (F08.00, F08.04, F13.01, F13.05).
