Mitsubishi inverter FR-E700 series is selected

When the inverter is used to form an active control system for control, in many cases, the PLC and the inverter are used together, and how to correctly connect the PLC and the inverter together has become the key to the success of the system. 1. PLC switch command signal input Inverter input ...

(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...

1. The so-called positioning is to let the servo motor go to a confirmed position. 2. This direction can be so incremental, or so ***. For example, we are now on the road, and we have to go forward 10 meters, which is equivalent to adding 10 meters to our bearing.

The new iQ-F motion module is a controller that can perform advanced motion control such as positioning, synchronization, cam, speed, torque, etc., with a computing cycle of 500μs, and can be connected to a high-function servo amplifier through CC-Link IE TSN, making a higher contribution to the miniaturization and high functionality of the equipment. ...

A. A scanning cycle is divided into input sampling, program fulfillment, and output rewriting. B. Each scanning process. The convergence samples the input signal. The convergence rewrites the output signal. C. Component image register ...

The main steps in the planning and commissioning of the programmable manipulator application system (1) In-depth understanding and analysis of the process conditions and control requirements of the controlled target a. The controlled target is a controlled mechanical, electrical equipment, production line or ...

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...

Servo drive system requirements 1. Wide speed regulation 2. High positioning accuracy 3. Satisfactory transmission rigidity and high speed stability 4. Fast response, no overshoot In order to ensure productivity and processing quality, in addition to the requirement of high positioning accuracy ...

01. Base system problem In Mitsubishi PLC, there are binary, octal, decimal, 10, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, remember the binary number from the back, divide every 3 into a group, and each group is converted into octal respectively, such as 1 ...

1. Routine control is consistent with safety control In the MELSEC-QS series, it is necessary to prepare a system for conventional control and a system for safety control. With the MELSEC iQ-R series of safe programmable controllers, it is possible to combine conventional and safe control into a single system. Quiet...

1. The cause of the failure (1) Unreasonable mechanical design leads to excessive radial load force; (2) The load side is stuck, or the moment of severe overload; (3) The motor and reducer are not centered when installed; 2. Fault cleaning ...

Ladder concept: It is a ladder pattern composed of graphical symbols that indicate the programming elements inside the PLC. Rules for writing ladders: Suitable for the left bus, finally the right bus The contacts should be drawn on the horizontal line, not ...

1. What is suspension? The so-called suspension refers to the fact that in the process of sequentially performing the program scanning, when there is a request to respond immediately, the scanning work performed at that time is immediately suspended, and the service work specified in the request is performed first. When the service job is complete, go back to ...

1. Mitsubishi servo drive alarm code AL31.1 Fault analysis: It is the motor overspeed alarm. Cause analysis: 1. The frequency of a single pulse of the input command is too high; 2. The acceleration and deceleration time is too small, resulting in overshoot and too large; 3. Mitsubishi servo system is unstable; 4. Electricity ...

The three output types of PLC are: transistor output, thyristor output and relay output, what is the difference between these three different output types? (1) Transistor output: The biggest advantage is that it is accustomed to high-frequency action, and the echo moment is short, generally about 0.2ms, but it ...

What is the reason why the programming software on the computer and the Mitsubishi PLC cannot communicate? How do I set the port of the communication line? There are several reasons why communication may not be available: 1. It may be that the PLC is not energized; 2. Programming software to create ...

When evaluating which process is suitable for which approach in the production environment, it is important to carefully consider the problem you want to deal with and consider all the costs that the robot can save: cutting waste, improving efficiency, improving yield, improving safety, or reducing labor costs. These costs ...

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 ...

The encryption process is as follows: ** Open the serial port for the first time [00000000] IOCTL_SERIAL_SET_BAUD_RATE Baud Rate: 9600 (Set baud rate here) [00000000] IOCTL_SERIAL_SET_LIN ...

The capacity (non-functional) of the Mitsubishi inverter of the drive motor can be understood from the change in energy activity determined by the operating method. 1. When operating at speed or constant speed The efficiency of the inverter is the output current, which is the ...
