1、 General fault handling
1. Voltage circuit breaker failure
The contact is overheated, and there is a smell in the distribution control cabinet. After inspection, it was found that the moving contact was not fully inserted into the static contact, and the contact pressure was insufficient, resulti...
Basic concepts of timing and counting
Ancient Chinese sages invented a vessel called the "drip glass" that measured time through flowing water. It drips water into the container through a fixed hole, with 3 drops per second, 180 drops per minute, and 10800 drops per minute, forming the earliest time...
Electric motors are the main control objects of drag control systems. In industrial control, the controlled objects have many operating modes, such as jog and continuous control. Under some working conditions, only a small capacity electric motor needs to operate continuously in one direction to mee...
Fundamentals of Network Communication
The communication of PLC includes communication between PLC and PLC, communication between PLC and upper computer, and communication with other intelligent devices. The communication between PLC and PLC is essentially still computer communication, connecting mul...
1、 Motors and their classification
Electric motor (collectively known as electric motor and generator) is a device that converts electrical energy into mechanical energy, and its operating principle is based on the law of electromagnetic induction. There are many specifications for motors, which ca...
Introduction to User Program Structure
The user program structure of S7-1200 and S7-300/400 is basically the same.
Modular programming
Modular programming divides complex automation tasks into smaller subtasks corresponding to the technical functions of the production process, each of which corresp...
The frequency of the frequency converter cannot be adjusted up. If there is no hardware damage, it is usually caused by the maximum torque output of the frequency converter being less than the load lifting torque. To put it bluntly, the frequency converter has poor load carrying capacity.

一 Electrical diagram and classification
Electrical diagrams are technical language used to illustrate the composition of circuits, the operating principles of components, electrical characteristics, and installation, debugging, maintenance, and use in electrical systems or equipm...
DC reactor is not a standard configuration for frequency converters, of course, this is for some brands. Therefore, when choosing a frequency converter, targeted instructions should be made, either directly stating that a DC reactor should be installed in the frequency converter, or limiting its pow...
Siemens S7-1200PLC Motion Control Foundation - High Speed Counter
The counting process of the ordinary counter in PLC is related to the scanning operation mode. The CPU captures the rising edge of the measured signal by reading it once per scanning cycle. When the frequency of the measured signal is...
