How does the Strander Controller Have No Output Signal?

How does the strander controller have no output signal?

In the process of using the strander, there may be extra work scale. If it exceeds the extra scale, the equipment will be abnormal. Excessive power grid fluctuation will lead to abnormal controller, frequency converter and sensor of strander. The main performance is that the controller has no output signal, and the frequency converter presents overvoltage or undervoltage alarm. So, how to deal with this situation?

The conventional way is to join a communication regulator at the power input of strander. After the strander controller is powered on, it will carry out system self-test to detect whether the signal of peripheral sensors is normal. When the sensor signal is abnormal, the controller will display the error code. The signal of the external button needs to be judged with the help of detection tools. After troubleshooting, the controller can start normally.
