Xinjie PLC cable design selection and construction anti-interference measures

It is necessary to route the signal line and the power line separately: When using the analog signal remote control inverter, in order to reduce the disturbance of the analog signal of the VFD and other equipment, please separate the signal line of the VFD control from the strong current circuit (main circuit and sequential control circuit). The spacing should be more than 30cm. Even in the control ...

The ladder diagram of the PLC can be understood as a programming language like the assembly and other calculator languages, but the scale of use is different! And the general practice is to convert your ladder diagram into C or assembly language (determined by the CPU used by the PLC), and then use the assembly or C compilation system to compile ...

Switch Mode Power Supply (SMPS) will cause the base of the switch tube to fail to get the switching pulse and intermittent operation due to the short circuit of the load, the failure of the vibration circuit itself and the loss of control of the protection circuit, which makes it difficult to locate the shortcomings of SMPS. Difficult to repair ...

The usual inverter motor (hereinafter referred to as VFD) can only regulate the speed of the communication motor, and it can be open-loop or closed-loop, depending on the control method and VFD. This is the traditional V/F mode. The basic concept of servo is accurate, precise and fast positioning. Frequency conversion is servo ...

One. How the system works The fresh air blown in by the fresh fan enters the room through the heating exchanger, refrigeration exchanger, and humidifier. In the room, the signals measured by the temperature, humidity, and differential pressure detectors are reflected to the controller. The heating and refrigeration exchanger is controlled by a digital manipulator by a reaction signal ...

Of course, PLC control is much more reliable than relay control, but if the device does not meet the requirements, it will not work. Therefore, the PLC machine should be installed correctly outside. (1) Pay attention to the environment of the installation The temperature should not be lower than 0°C and above 55°C, for example, not installed by a large stove, and ...

CNC machine tool is the abbreviation of digital control machine tool, which is an automatic machine tool equipped with a program control system. The control system is the numerical control system, the numerical control system can logically process the program with the control code or other symbolic instruction rules, and decode it, so that the machine tool action and add ...

Model introduction of Xinjie PLC 　　XC series Including XC1 (economy), XC2 (basic), XC3 (standard), XC5 (enhanced), XCM (sport), XCC (high-performance) and their corresponding expansion modules, as well as special analog bodies and other special models. XC series PLC can be ...

Why does the motor driven by the inverter overheat? This is due to the fact that the voltage of the inverter drive motor contains a rich high-frequency component. The voltage waveform of the inverter-driven motor is not a sine wave voltage, but a pulse-width modulation (PWM) voltage. According to Fu Liye's analysis, this waveform ...

1. The speed regulation power is high, which is an efficient speed regulation method. This is because after the frequency change, the motor is still working in close proximity to the synchronous speed, and the rated slip is fundamentally adhered to. It's just that in the frequency conversion equipment system, there will be conversion loss, and because of the influence of higher harmonics, the loss of the motor will increase.

1、CPU。 The CPU of the plc is actually the central processing unit, which can carry out the operation and processing of various data, convert various input signals into input registers, and then carry out logical operations, timing, counting, arithmetic operations, data processing and transmission, communication networking and various operations, ...

1. High reliability The PLC adopts a series of anti-interference methods in hardware and software, so that it can be directly installed in the industrial site and operate safely and reliably, anti-magnetic, anti-seismic and dust-proof. 2. Programming is simple and easy to grasp ...

What is a frequency converter? Variable frequency drive (VFD) uses inverter technology and microelectronics to change the operating power frequency of the motor to control the power control unit of the communication motor. The inverter is mainly composed of rectifier (from communication to DC), inverter, inverter (from DC ...

Following the launch of XDH, XLH series 16-axis and other models, Xinjie has achieved good market feedback, and the XLH-30A32 low-profile controller to be launched today can be expanded by 32 bus nodes, and has better performance in basic performance and bus control ability. ...

Although many relays, timers and counters are often used in the ladder diagram programs used by PLCs, PLC does not have these hardware physically, but uses memory and program programming methods to do logic control and editing, and connects external mechanical devices to make physical devices through output components.

1. Air opening: a total air switch, which is the power control of the entire cabinet. I believe that every cabinet must have one thing. 2. PLC: This should be selected according to the needs of the project. For example, if the project is small, it can be an integrated PLC, but if the project is more ...

Since the advent of the MS6 series B1 and B2 servo motors, they have been widely recognized by customers for their outstanding performance advantages, and their performance in terms of temperature rise, overload ability, overspeed range and protection level is far better than that of MS5 series servo motors. This MS6 series B3 motor released will ...

On March 19, 2021, the "Made in China Digital Service Summit 2021 CAIMRS and Annual Selection and Award Ceremony" held by China's industrial control network was broadcast live on the cloud of the "Industrial Control Network Digital Conference Hall". At the meeting, Pan Yingzhang, President of Gongkong®, officially released China's automation and digital ...

Xinjie touch screen is an extraordinary technology product developed by Xinjie Technology Company. It not only uses touchscreen skills, but also integrates cutting-edge skills in many fields such as human-computer interaction, visual arts, and information processing, bringing skills to users. ...
