How to resolve stall overvoltage on hpmont HD09-4T5P5G Inverter?
If your hpmont Inverter is experiencing stall overvoltage, the bus voltage might be too high, so check the power input or the function of the brake. Alternatively, the setting of stall overvoltage might be too low, so set the value of stall overvoltage properly (F19.19).
What causes fault of power module in hpmont Inverter?
If your hpmont Inverter reports a fault in the power module, there might be a short circuit between phases output, so check the connection and connect the wire properly. There could be a short circuit to the ground, so check the connection and connect the wire properly. The output current might be too high, so check the connection and mechanism. The power module itself might be damaged, so please contact the supplier for repairing.
What to do for DC bus acceleration over voltage on hpmont Inverter?
If your hpmont Inverter shows a DC bus acceleration overvoltage, the input voltage might be too high, so please check the power input. The deceleration time might be too short, so set a proper value for deceleration time (F03.02). Improper wiring could lead to overvoltage of hardware, so check the wiring and wire the inverter properly. It may also be due to improper selection of the braking devices, so select according to the recommended braking devices of section 5.2 Braking Resistor, page 16.
What causes motor overload on hpmont Inverter?
If the hpmont Inverter indicates a motor overload, the V/f curve setting might be incorrect, so adjust the setting of V/f curve (F09.01 - F09.06). The mains supply voltage might be too low, so check the power input. It's possible the motor is running for a long time with a heavy load at low speed, so please use a special motor. Also, the motor might be running with blocked torque or the load is too heavy, so check the load and mechanical transmission devices.
Why is my hpmont HD09-4T5P5G Inverter heatsink overheating?
If your hpmont Inverter's heatsink is overheating, the ambient temperature might be too high, so consider using an inverter with higher power capacity. The inverter's external ventilation might be poor, so improve the ventilation around it. There could be a fan fault, so replace the cooling fan. It may also be a fault in the temperature detection circuit, so please seek technical support.
Why is my hpmont HD09-4T5P5G overloading?
An hpmont Inverter might overload due to several reasons: the acceleration time being too short, improper settings of the V/f curve or torque boost leading to overcurrent, low mains supply voltage, or the motor load being too high. To resolve this, try the following: * Adjust the acceleration time using parameter F03.01. * Adjust the V/f curve (F09.01 - F09.06) or torque boost (F09.07, F09.08). * Check the mains supply voltage. * Use an inverter with a proper power rating.
What to do if my hpmont HD09-4T5P5G is overloaded?
If your hpmont Inverter is overloaded, it could be due to several reasons. The acceleration time might be too short, so adjust the acceleration time using parameter F03.01. The V/f curve or torque boost settings might be causing overcurrent, so adjust the V/f curve (F09.01 - F09.06) or torque boost (F09.07, F09.08). Also, check the mains supply voltage and ensure it's adequate. If the motor load is too high, consider using an inverter with a proper power rating.
What to do if hpmont HD09-4T5P5G shows Fault of external equipment?
If your hpmont Inverter indicates a fault with external equipment due to a fault terminal operating, check the external equipment.
What to do if hpmont Inverter 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. To address this, replace the contactor.
What causes SCI communication time-out in hpmont HD09-4T5P5G?
SCI communication time-out with your hpmont Inverter can be caused by a connection fault in the communication cable, or if the cable is disconnected or not well connected. To resolve this, check the connection.
