What to do if hpmont Inverter has SCI communication time-out?
If your hpmont Inverter experiences an SCI communication time-out, check the connection of the communication cable. Ensure it is properly connected.
What to do if hpmont HD20 has SCI communication error?
If your hpmont Inverter shows an SCI communication error, check the connection of the communication cable to ensure it is properly connected. Correctly set the communication format (F17.00) and the baud rate (F17.01). Ensure that the data is sent according to the Modbus protocol.
What to do if hpmont HD20 parameters auto- tuning fault?
If your hpmont Inverter experiences a parameter auto-tuning fault, check the motor’s connection to ensure it is properly connected. Input the correct motor parameters (F08.00 - F08.04). If the issue persists, please seek technical support.
What to do if my hpmont HD20 Inverter is overloaded?
If your hpmont Inverter is overloaded, it could be due to several reasons. First, adjust the Acc. time using parameters F03.01, F03.03, F03.05, and F03.07. Also, ensure you have input the correct motor parameters (F08.00 - F08.04). Adjust the V/f curve (F09.00 - F09.06) or torque boost (F09.07, F09.08). If instant power-off occurs, set the start mode to speed tracking (F02.00 = 2). Check the mains supply voltage and ensure it is adequate. Finally, verify that you are using an inverter with the proper power rating, as the motor load might be too high.
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 output is unloaded?
If the output of your hpmont Inverter is unloaded, check the load and mechanical transmission devices for any issues. Also, ensure that the parameters are set properly using settings F20.03 to F20.05.
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.
What to do if hpmont HD20 has fault of output phase?
If your hpmont Inverter reports a fault in the output phase, check the connection between the inverter and the motor. Also, verify the quality of the motor itself.
What to do if hpmont HD20 has fault setting of parameters?
If your hpmont Inverter displays a fault related to parameter settings, it might be due to a significant difference in power rating between the motor and the inverter, or improper motor parameter settings. Select an inverter with a suitable power rating. Set the correct value of motor parameters using settings F08.00 to F08.04.
What to do if hpmont HD20 has stall overvoltage?
If your hpmont Inverter is experiencing stall overvoltage, check the power input or the function of the brake, as the bus voltage may be too high. Also, ensure that the value of stall overvoltage is set properly.
