Analysis of problems encountered by Xinjie PLC

The internal disturbance of the PLC system is mainly caused by the mutual electromagnetic radiation between the components and circuits inside the system, such as the mutual radiation of logic circuits and their influence on the imitation circuit, the interaction between the imitation ground and the logical ground and the mutual mismatch between components. How to deal with PLC long distances effectively ...

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.

Input and output module, if it is the kind of relay output, it is normal to have a little movement, because the relay is a mechanical equipment, there will be a little noise during the action, but the average person can not hear it, if it is obvious, it is estimated that the relay is broken, such as a short circuit between the turns of the coil, please pay attention to: Rongji point ...

1. PLC input and output A small PLC controls a complex system with agility, and what can be seen is the upper and lower rows of staggered input and output relay terminals, corresponding lamps and PLC numbers, just like a piece of integrated electricity without dozens of feet. If any ego doesn't look at reason...

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 ...

1. The inverter is used in the air conditioning load class Office buildings, shopping malls and some supermarkets and factories have central air conditioning, and the electricity consumption of air conditioning is very large at the peak of electricity consumption in summer. In the hot climate, Beijing, Shanghai, Shenzhen air conditioning ...

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 ...

The frequency converter is a power converter in the motion control system. Today's motion control system includes many technical fields, and the general development trend is: communication drive, high-frequency power changer, digital, intelligent, and networked control. VFDs are power converters in motion control systems. ...

Li Xin, Chairman of Xinjie Electric, Feng Guangwei, Deputy Director of the Electronic Information Department of the Investment Promotion Bureau of the Airport Pilot Zone, and Liu Guangwei, Executive President of Foxconn Technology Group.

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.

The output voltage of low-voltage general frequency conversion is 380-650V, the output power is 0.75-400kW, and the working frequency is 0-400Hz. Its control methods have gone through the following four generations. 1U/f=C Sine Pulse Width Modulation (SPWM) Control Method ...

The most direct cause of cable problems is the breakdown due to the loss of insulation. First of all, there are: a. Overload operation. Long-term overload operation will increase the temperature of the cable, aging the insulation, resulting in breakdown of insulation and degradation of construction quality. b. Electrical: the construction process of the cable head does not meet the requirements.

Make accurate punctuality, read accurate punctuality, and stop accurate punctuality. Watchman number. Range: T600 - T618 (T600, T602, T604...) T618, numbered even) Punctuality. Accurate punctuality ...

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 ...

Xinjie XDM series PLC, XDM is the sports control PLC in the XD series, now has the following types: XDM-24T4-E/C, XDM-32T4-E/C, XDM-60T4-E/C, XDM-60T10-E/C. The XDM series has the following ...

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. 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...

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 ...
