How do I fix output earthing on my Alpha 6000S?
If the Alpha Inverter is experiencing output earthing issues, and the output earthing current exceeds the specified value, check whether the motor insulation has become poor. Also, check whether the connection line between the frequency inverter and the motor is damaged.
Why is the heat radiator overheating on my Alpha Inverter?
If the heat radiator of the Alpha Inverter is overheating, the environment temperature might be too high, so reduce the environment temperature. The air duct could be blocked, so clear the air duct. The fan may be working abnormally or damaged, so replace the fan.
What does an external fault with RS485 serial communication mean on my Alpha Inverter?
If the Alpha Inverter displays an external fault with the RS485 serial communication, the serial (MODBUS) transmission may be wrong, so set the correct timeout detection time or set the Pb.03 timeout detection time as 0.0s. A fault may be caused by the external control circuit, so check the external control circuit. Check the input terminal conditions. If terminals are not used but the fault is still displayed, please seek the technical support for settlement.
