Xinjie PLC problems and solutions

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. Save the transformation cycle, no need for large-scale construction: eliminate the trouble of wiring maintenance, and easily complete the transformation within one day and meet the requirements of communication stability. 2. The device is simple, no programming is required: the wireless communication terminal only needs to ...

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 ...

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. ...

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) There is no need to adjust the parameters, we can maintain the original parameters (default value) when the inverter leaves the factory. (2) It is the parameter that needs to be set and changed before the trial operation. (3) It is a parameter that is adjusted in the operation of the demand. Frequency converters ...

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.

Tile programming features The editing and display mode in all Chinese greatly improves the readability of the program; Customizable programming instructions. Not only can the name of the instruction be modified according to the characteristics of the industry, but also the instruction can be added or deleted according to the needs of the equipment; Adopt a procedural editing mode. ...

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.

1. The switching quantity is also called the logical quantity, which means that there are only two values, 0 or 1, ON or OFF. It is the most commonly used control, and it is the advantage of PLC to control it, and it is also the most basic use of PLC. The intention of switching quantity manipulation is to use the current input combination of the switching quantity with the historical input ...

1. Maintenance of the inverter itself: Instantaneous overcurrent, overvoltage, undervoltage, overload, short circuit to ground, abnormal control circuit, then for the maintenance of the inverter itself, the overcurrent, overvoltage, undervoltage and so on set the limit value, when the inverter is running, if ...

The suffix is XT and only supports RS232 communication, 4 inches out. The suffix MT supports RS 232/485/422 communication. The suffix is UT on the basis of MT, and a U disk port is added, which can be used to import and export engineering and CSV data from U disk. The suffix is named ET and is added to the UT ...

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. Check the full-load power supply of the inverter (Variable-frequency Drive (VFD). 1. Ground the terminal strip of the VFD. 2. Type the switching power supply of VFD into the terminal and receive it from the switching power supply through the power switch of the leakage protector. 3. ...

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 ...

In order to prevent the control signal line between the PLC and the inverter from being disturbed by the space electromagnetic field, the outer layer of these control signal lines can be connected with shielded wires to improve the anti-interference ability of the system. This kind of wiring must be noted, and only one point can be selected for the shielded connection address. Whether it's on the PLC side, or ...

W-BOX is a 2.4GHzWifi-based wireless communication module independently developed and recently launched by Xinjie in line with the trend of wireless communication. W-BOX can be connected with wireless AP (hotspot) in various occasions to complete long-distance monitoring of PLC and overall control of PLC wireless networking in various environments.

1. On the premise of satisfying the production equipment and process requirements, the acceleration or deceleration time should be increased as much as possible, and then the overcurrent generation in the process of acceleration or deceleration can be avoided. 2. Check whether the inverter, motor, and production equipment are well matched, whether the transmission part is sensitive, and whether the material is ...
