What does PG disconnection mean on hpmont : HD5L-4T5P5?
- JjonathanhicksSep 9, 2025
If the hpmont Controller displays 'PG disconnection', it means the PG is without an input signal. Check the PG connection.
What does PG disconnection mean on hpmont : HD5L-4T5P5?
If the hpmont Controller displays 'PG disconnection', it means the PG is without an input signal. Check the PG connection.
Why did the soft start fail on my hpmont : HD5L-4T5P5 Controller?
If the hpmont Controller indicates a 'Soft start failed' error, it could be due to a contactor fault or a fault in the control circuit. Replace the contactor.
What does SCI faulty mean on hpmont : HD5L-4T5P5?
If your hpmont Controller displays 'SCI faulty', it could be due to a connection fault in the communication cable, the cable being disconnected or not well connected, a communication setting error, or communication data error. Check the cable connection, correctly set the communication format and baud rate, and ensure data is sent according to the MODBUS protocol.
What to do if my hpmont Controller is overloaded?
If the hpmont Controller is overloaded, this could be due to several reasons: the acceleration time might be too short, the V/f curve or torque boost settings could be causing overcurrent, the mains supply voltage might be too low, or the motor load could be too high. To resolve this, try adjusting the acceleration time and the V/f curve or torque boost. Also, check the mains supply voltage and consider using a controller with a more suitable power rating.
What to do if hpmont : HD5L-4T5P5 reports lack of input?
If the hpmont Controller reports a lack of input, and you are using a three-phase input controller, it indicates a phase loss fault in the power input. Check the three-phase power input.
What does 'Parameter setting faulty' mean on hpmont Controller?
If your hpmont Controller is showing a 'Parameter setting faulty' error, it could be because the power rating between the motor and the controller is too different, or the motor parameters are set improperly. Select a controller with a suitable power rating and ensure that the motor parameters are set to the correct values.
How to resolve motor overheat in hpmont : HD5L-4T5P5 Controller?
If the hpmont Controller indicates a motor overheat, it could be due to the motor actually overheating, an incorrect connection of the motor overheat terminal (digital or analogue input terminal), or incorrect motor parameter settings. Reduce the load, increase the acceleration/deceleration time, and repair or replace the motor if necessary. Verify the overheat detection input signal for correctness and set the motor parameters according to the motor’s nameplates.
What to do if hpmont : HD5L-4T5P5 has lack of output?
If the hpmont Controller is showing a lack of output, this could be due to output phase disconnection or loss, or a heavy imbalance of the controller’s three-phase load. Check the connection between the controller and the motor and verify the quality of the motor.
What causes motor over speed in hpmont : HD5L-4T5P5?
If your hpmont Controller reports a motor over speed, this could be due to a PG pulse number fault, inadequate controller torque, or incorrect speed-loop PI parameter settings. Set the proper PG pulse number, select a bigger capacity controller, and correctly set the speed-loop PI parameter.
How to troubleshoot DC bus undervoltage on hpmont : HD5L-4T5P5?
If you are experiencing DC bus undervoltage with your hpmont Controller, it could be due to normal power on/off cycling, low input voltage, or improper wiring. Check the input power voltage and ensure the controller is wired properly. Note that undervoltage can occur at the beginning of power on and at the end of power off, which is normal.
