Application characteristics of PLC in the control of mixing plant

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. ...

There are many novices who are not familiar with the false load about the maintenance inverter, and the maintenance inverter uses the false load to keep many of their modules, because the maintenance novice generally does not know how to do this, and now the electric light is on to clarify that the module is going to be broken. A dummy load is a load with a resistor of several hundred ohms ( ...

Radiative disturbance from space The most useful method for radiation disturbance is metal shielding. Space radiated electromagnetic fields are mainly caused by power networks, lightning, radio broadcasting, radar, etc., and are generally referred to as radiation disturbances. Its impact mainly goes through two paths: one is ...

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 ...

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, ...

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...)

As one of the important equipment for manufacturing motors, the six-station high-speed inner winding machine is widely used in electric fans, range hoods, purifiers, automobiles and other occupations. Now there are single station, double station, four station and six station winding machine types, and the six-station inner winding machine launched by Xinjie can reach up to 1200 times/i ...

The motion control mainly touches the control of stepper motors and servo motors, and the control structure mode is generally: control equipment + driver + (stepper or servo) motor. The control equipment can be a PLC system, or a special automation device.

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 ...

Common problems with Xinjie touch screen Poor contact Touch screen installation problemRemove the screen from the control cabinet and perform an operational test. If there is no problem with the operation, i.e. the installation problem causes the installation size to be re-measured, do not install it too tightly so as not to squeeze the touchpad. Correspondence...

A universal inverter is an electronic device used to control the speed of an electric motor, which can change the speed of the motor according to the demand, and then achieve higher output power and power savings. Universal inverters have a wide range of application scales and can be used for various types of electric motors, including communication motors, direct ...

(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 ...

From 14:00 to 15:20 on May 14 last year, the X-SIGHT visual brand conference with the theme of "Vision, Light Up Intelligent Manufacturing" was held online, officially announcing that Wuxi Xinjie and Intel will join hands to create a new era of intelligent manufacturing. X-SIGHT unveiled a new Intel chip-based ...

Problem example 1 On the telegram OC problem, measure the 5, 6, and 7 pins of N1 to be 2V. Pin 7 is not 0V for the alarm reason. 1. The "imaginary short" rule of the amplifier is still established, and the N1 chip is good to judge, but the fault is in the bias circuit. 2. Further analysis, at this moment the differential amplifier has ...

　　1. Four-wire resistive touch screen: It is not afraid of dust, oil and photoelectric disturbance, and is afraid of scratches is its main defect. It is suitable for public places with fixed users, such as industrial control sites, offices, homes, etc.; 2. Five-wire resistor ...

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) The PLC itself should be grounded according to the specified wiring specifications and grounding conditions, and attention should be paid to prevent the use of common grounding wires with Xinjie servo, and the two should be separated as much as possible when grounding. (2) When the power supply condition ...

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 ...
