What to do if hpmont HD3L-4T7P5 Controller shows 'Too small running current'?
If the hpmont Controller shows a 'Too small running current' message, it may be due to improper settings of F16.14 and F16.15. Correct the setting of F16.14, F16.15, check the connection between the controller and motor, detect controller whether output, and detect whether the output contactor work is normal.
What to do if hpmont HD3L-4T7P5 shows 'Input voltage phase loss'?
If the hpmont Controller displays 'Input voltage phase loss', the power input to the three-phase unit is experiencing a phase loss fault. Check the three-phase power input.
Why is my hpmont Controller overheating?
The hpmont Controller's heatsink may be overheating due to several reasons: the ambient temperature is too high, there is poor external ventilation, the fan is faulty, or there's a fault in the temperature detection circuit. To resolve this, consider using a controller with a higher power capacity, improve ventilation around the controller, or replace the cooling fan.
How to troubleshoot SCI communication error on hpmont HD3L-4T7P5?
An SCI communication error with the hpmont Controller can arise from a faulty or disconnected communication cable, or errors in communication settings or data. Check the connection, ensure the communication format and baud rate are correctly set, and verify the data is sent according to the MODBUS protocol.
How to fix faulty setting of parameters on hpmont HD3L-4T7P5?
Faulty parameter settings on the hpmont Controller can result from a significant difference in power rating between the motor and controller, or from incorrect motor parameter settings. Select a controller with a suitable power rating and set the correct value of motor parameters.
What causes excessive speed deviation in hpmont HD3L-4T7P5?
Excessive speed deviation in the hpmont Controller can stem from a brake or contactor fault, PG pulse number fault, improper settings of F05.19 and F05.20, inadequate controller torque, or incorrect speed-loop PI parameter settings. Try changing the contactor, set the proper PG P/R, correct the setting of F05.19, F05.20, select a controller with bigger capacity or correctly set speed-loop PI parameter.
What to do if hpmont HD3L-4T7P5 Controller displays 'Output voltage phase loss'?
If the hpmont Controller indicates 'Output voltage phase loss', there may be a phase disconnection or loss, or the three-phase load is severely unbalanced. Check the connection between the controller and the motor and verify the quality of the motor.
What causes motor over speed in hpmont HD3L-4T7P5?
Motor over speed in the hpmont Controller can be caused by a PG pulse number fault, inadequate controller torque, or incorrect speed-loop PI parameter settings. You can set the proper PG pulse number, select a bigger capacity controller or correctly set speed-loop PI parameter.
How to resolve DC bus undervoltage on hpmont Controller?
DC bus undervoltage on the hpmont Controller can occur at power on/off, if the input voltage is too low, or if there's improper wiring. Check the input power voltage and ensure the wiring is correct.
What to do if hpmont HD3L-4T7P5 Controller shows 'Acc over voltage'?
If the hpmont Controller is showing an 'Acc over voltage' error, the input voltage might be too high, the deceleration time might be too short, or the wiring is improper. Check the power input, set a proper value for Dec time, and verify the wiring.
