What are the faults that Industrial automation equipment may encounter during the application process?

With the continuous improvement of technology and production processes, there are also more and more fields using  Industrial automation equipment. But there are still some problems with Automated integrated equipment now, mainly due to external factors and equipment itself.

From the perspective of the causes of faults, there are hard faults and soft faults, and both types of faults can also exist simultaneously; In addition, faults can be divided into static faults and dynamic faults. Static faults are relatively easy to observe and eliminate. It seems that Automated equipment may experience malfunctions.

1. Power supply malfunction

This type of fault is a static fault. The occurrence of such faults is mostly caused by open circuits, misconnections, or poor contacts in the power or ground wires. Of course, it is also possible that the input voltage of the equipment or circuit board components exceeds the allowable deviation range, or the output voltage of the power components themselves exceeds the allowable deviation range due to circuit faults.

2. Passive components malfunction

This situation is mainly caused by open circuit of capacitors, loose and falling end caps of resistors, and changes in resistance values. If the resistance value changes, it may cause fuzzy logic values. If the capacitance value changes, it may lead to poor decoupling, changes in oscillator frequency, and equipment such as motors that cannot be started.

3. Poor decoupling of power supply

This problem usually occurs when the interference waveform overlaps with the normal waveform. Large capacity filtering capacitors and ceramic capacitors with excellent high-frequency performance can be used to prevent these interferences.

In addition to the above faults, there may also be software design faults, equipment design faults, and poor contacts. It is difficult to avoid faults in Automated equipment, but it is necessary to identify the cause of the problem, find methods to improve or prevent it, and the number of faults in Automated equipment during operation will also decrease.
