1. Select the power supply with excellent performance and press the disturbance introduced by the power grid The power supply of the PLC controller is powered by a non-power line, and is powered by a special line directly led by the main bus of the low-voltage distribution room. Barrier transformer should be selected, the transformer capacity should be 1.2-1.5 times larger than the actual need, and can be used in the barrier...

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 ...

1. Operating temperature. The inverter is a high-power electronic component, which is easily affected by the operating temperature, and the product is generally required to be 0-55 °C, but in order to ensure the safety and reliability of the operation, it should be considered to leave room for use, and it is best to control it below 40 °C. In the control box, the inverter ...

1. Non-short-circuit overcurrent, which is mainly due to: (1) The motor is severely overloaded. (2) The motor accelerates too fast. (3) Due to the U/f ratio (torque compensation) setting is too high, the motor is in a light load condition. 2. Short circuit ...

(1) The PLC shall be installed in an environment that meets the requirements of the rules. (2) In order to facilitate ventilation and disassembly, a space of more than 80mm should be left around the PLC. (3) PLC should be a vertical device and not a horizontal device, that is, the device universal is the direction in which the words on the unit panel can be read normally, otherwise the PLC ...

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. ...

PLC programmable logic manipulators are the core part of industrial control. According to the number of I/O points of PLC, PLC can be divided into three categories: small PLC, medium and large. It is a digitally operated electronic device designed for industrial production. It uses a programmable memory to store programs that execute user-facing ...

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 ...

PLC is the abbreviation of programmable logic manipulator, which is a digital operation manipulator with a microprocessor for automatic control, which can load control instructions into memory at any time for storage and fulfillment. PAC is an abbreviation for Programmable Automation Manipulator. PAC in industrial control ...

(1) Whether there is an abnormal change in the sound during the operation of the motor, including whether there is vibration during the operation of the motor. (2) Whether the installation environment of the inverter has changed. Whether the ambient temperature is normal, the operating temperature of the inverter is generally required to be in the range of -10 °C - +40 °C, and it is better to take about 25 °C.

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 ...

At present, in the domestic PLC market, there are many kinds, but there are not many domestic PLC manufacturers with real strength, most of the domestic PLC is not an individual without legal person qualifications, or a single-chip microcomputer enthusiast, from the domestic PLC factory to buy the underlying programming code or buy a domestic PLC chip (the domestic P ...

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) Investigation and investigation of problem phenomena. There are many kinds of inverter problem phenomena, for example, the same type of problem may have different problem phenomena, and different types of problems may have the same problem phenomenon, which brings difficulties to find the problem. However, the problem phenomenon is the basic basis for overhauling the inverter ...

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 ...

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. Introduction TP Contact Industrial Graphic Displayer (referred to as contact screen) is a human-machine interface (known as HMI or MMI in foreign countries) that connects humans and machines (mainly PLC), which is known as the face of PLC. It is a generation ...

Introduction to Thermal Transfer Transfer printing refers to a printing method that selects the corresponding pressure to transfer the graphics and text on the intermediate carrier film to the substrate, and according to the different selection pressures, transfer printing can be divided into water transfer printing, heat transfer printing, air transfer printing, screen transfer printing, low temperature transfer printing and so on. In the meantime, the heat ...

1. Why can't the PLC communicate with the peripherals? Communication failures are generally summarized as the following problems: 1. Communication cable: The connection may be incorrect, or the contact is poor, the user can change the communication cable and try again. 2. Communication parameters: PLC communication port and peripheral equipment ...
