1. Common problem phenomena When the RS-485 port of the PLC is connected to the computer through the non-blocking PC/PPI cable, the connection between the PLC and the PLC, or the communication between the PLC and the inverter, touch screen, etc., the communication port is damaged, and the more common damage conditions are as follows: (1) R1 or R2 is burned ...

XC can be divided into multiple sub-series according to the incompatibility of functions, including XC1 (economy), XC2 (foundation), XC3 (standard), XC5 (enhanced) and their corresponding expansion modules, as well as special imitation ontology, activity control models, etc. Powerful function, complete variety, can be full ...

After overhauling and confirming that all connections of the system are correct, power on the relevant modules until the card indicator shows normal. The initiation process of the system after the scheduled repair is as follows: (1) Power supply. Turn on the power supply equipment (including the UPS...)

Motor overload: There is no need to set overload maintenance parameters in frequency conversion. The inverter generally acquiesces to the motor overload maintenance based on the motor power. Generally, it is 1.2 times 60 seconds to report the overload problem. The overload factor is not the same for different frequency converters. ...

Communication: (1) Radiation disturbance; (2) Conduction disturbance Anti-disturbing method: Regarding the disturbance signal transmitted by the radiation method, it is mainly weakened by wiring and shielding the radioactive source and the disturbed line. With regard to the disturbance signal transmitted through the line, ...

1. Look inside the electrical cabinet, for example, to see if there are small animals and their droppings, and whether there are condensation or water marks. If the dust in the cabinet is large, please clear the external radiator of the inverter. 2. Assuming that the humidity is relatively large, there are condensation or water marks, please open the cabinet door first, ventilate and dehumidify, you can use electric fans, etc.

1. When the PLC and the host computer (or touch screen) form a monitoring system, there are many times on the screen that there are "manual", "active" and other control modes (generally more than one). In the program, you can use the "MOV" command. For example, when selecting "manual", the constant 1MOV will be ...

Confirm the rated power and resistance value of the braking resistor. The rated power of the braking resistor should be determined according to the power and moment of inertia of the motor, and the resistance value should be selected according to the specifications of the VFD. In the VFD's parameter settings, find the parameters related to the braking resistor, such as the braking resistor selection ...

A：a. Now only the TGM series touchscreen supports penetration as well as network connectivity b. At present, the penetration function only supports the PLC class of Xinjie that supports the Xnet protocol, and other models do not support it temporarily c. Check whether the computer has the latest version of config installed serial port equipment tool (soft ...

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 ...

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 ...

The XDHI XLH series of 16-axis high-performance EtherCAT controllers is the perfect choice for small motion control. Product model XDH-30A16-E/XDH-30A16L-E Small/16-axis type Frequency: 600MHz Program Capacity: ...

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 ...

With the continuous development of industrial automation, PLC is widely used in industrial control professions. No matter how strong the PLC product is, it often fails to work normally. All kinds of brands of PLC have the function of self-diagnosis, but the skill of PLC repair is that when the PLC is abnormal, the function should be fully used.

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. ...

Why can't the touch screen software be installed or used properly? 1. Before the device, please close the antivirus software and system optimization things; 2. After the device is successful, double-click the software convenience icon on the desktop, "Please set the display to be true color" prompt ...

Xinjie PLC 丨Communication failure is generally summarized as the following problems: (1) Communication parameters: The communication parameters of Xinjie PLC communication port and peripheral equipment may be inconsistent. (2) Communication line: The connection may be incorrect, or the contact is poor, the user can replace the communication line and try again.

As the only domestic brand among the top 10 small PLC shopping malls in China, Xinjie has broken through the core shopping malls dominated by international brands for more than ten years, and the unswerving commitment of the leader Li Xin to independent development can be seen. ...

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 ...

1. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reason for this problem is explained and stated as follows. Depend on...
