After the first installation of different servo motors on the machine, they may be poorly matched to the machine during operation, resulting in vibration, noise and other phenomena. The cause of the problem is a mismatch between parameters such as the rigidity of the servo motor and the load-inertia ratio and the machinery. Due to the large number of parameters that affect ...

Mitsubishi inverter we have to maintain the inverter module frequently, to regularly check the Mitsubishi inverter module, especially the maintenance of the cooling fan, due to the high power of the cooling fan, high speed, in the dusty working environment, simply lead to the radiator exhaust hole blockage, so that the internal electric ...

Mitsubishi inverter OC (overcurrent problem) will be caused by the following reasons, taking A500 series inverter as an example: 1). Caused by improper parameter setting problems, such as time setting is too short. 2）. ...

1. For the switching input and output circuits, pay attention to the consistency criterion of maintaining the state; The positive logic criterion is usually used, that is, when the input and output are live, it is in the "ON" state and the data value is "1"; Conversely, when the input and output are powered off, it is in the "OFF" state and the data value is "0". Such...

Introduction to the names and effects of capacitors in different circuits Capacitor is a kind of energy storage element, with the characteristics of "straight through AC, low frequency through high frequency", people in order to know and identify the capacitor in different circuits, according to its effect in the line and give it many names, understand ...

1. Control the start, stop, speed and so on of the servo motor; 2. Carry out various maintenance on the motor (overload, short circuit, undervoltage, etc.) 3. Respond to external signals, and control the servo motor (position, speed, torque) after internal PID conditioning; The manipulator is the control of the electric ...

(1) Random Access Memory (RAM) The user can read out the content of the RAM with the programming device, and can also write the user program to the RAM, so the RAM is also called read/write memory. It is volatile memory, and when its power is interrupted, the stored information is lost. The use of the computer's memory module ...

PLC is an industrial small computer, it has a problem, the first thing to clean up is the PLC ontology problem is still a peripheral problem, if there is a problem with the PLC ontology, often the ERR light is on, maybe the red light is flashing, the normal situation is generally RUN running green light, if it is the ontology to produce this kind of problem, ...

When you are ready to communicate through AJ71QE71, perform the ping procedure in MS-DOS mode to check if the connection is correct before the Mitsubishi PLC's GPPW starts to communicate. Support communication with Weilun touch screen through serial port. Under...

1. If the PLC stops in the middle of some outputs where the output is excited, then look for the signal that caused the next operation (input, timer, line, drum manipulator, etc.). The programmer will show the ON/OFF status of that signal. ...

When the contact screen is connected with the PLC, in fact, the memory of the PLC is used, (the contact screen also has a small amount of memory, which is only used to store system data, that is, the screen, controls, etc.), the contact screen and the PLC communication is generally a master/slave relationship, that is, the contact screen reads data from the PLC, and after making a judgment, it is displayed in the display ...

01. Base system problem In Mitsubishi PLC, binary, octal, decimal 10, hexadecimal, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, the binary number is remembered from the back, every 3 dividends in a group, each group is separated into 8 bases, such as 1 ...

1. Motion manipulator The use of motion control in the field of robotics and CNC machines is more chaotic than in specialized machines, which are more sketchy and often referred to as General Motion Control (GMC). 2.plc Programmable logic manipulators are a kind of specialized ...

There is a capacitance between the wires of the cable, and a qualified cable can limit this capacitance to a certain size. It is a qualified cable, when the cable length exceeds a certain length, the capacitance value between the lines will also exceed the required value, when the cable is used for PLC input, the capacitance between the lines will be ...

(1) Eliminate finger tremor: use the differential instruction DIFU (13) to retrieve the rising edge of the button to send the electrical signal, and the PLC only executes it once in an execution cycle, and then prevent such misoperation; (2) Unconscious operation: (1) Optimize the display function and use different fingers...

In the process of using the PLC control system, it is often necessary to correct some parameters, and the most common is to correct the set value of the timer. In order to facilitate the operator to correct the set value of the timer, the following methods can be used: 1. The use of man-machine ...

Mitsubishi PLC split source type (PNP) or drain type (NPN), here are their differences 1: Leakage logic: When the current flows out of the signal input terminal, the signal becomes ON, which is leakage logic. The current flows through the terminals and has the output characteristics of an NPN transistor. 2: Source logic: When ...

The processor performance test should be carried out in accordance with the requirements of the system manual, to ensure that the system has the function described in the manual, and is stable and reliable, including the system communication, backup battery and other special modules to view. Redundancy testing is necessary for systems with redundant equipment. i.e. the redundant design ...

The PLC control cabinet is the final level of equipment in the power distribution system. It mainly protects, supervises and controls the entire circuit, which is convenient for unified management. The power distribution cabinet is a kind of equipment that can reasonably distribute electrical energy and make the circuit easy to open and close. But because it is a circuit device, the requirements for the level of safety protection ...
