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 ...

E6, E7 fault for the majority of users must not be unfamiliar, this is a more common Mitsubishi inverter typical problem, of course, the cause of damage is also multifaceted. IC 1302H02 is damaged, which is a piece of integrated drive ...

In the process of operation, low-voltage electrical appliances will present problems due to improper use or long-term operation of aging components, and there are many kinds of problems, and the common problems are analyzed and dealt with. 1. Contact problems and repairs The contact is the primary component of the low-voltage switching coupon, ...

1. Main substrate There are a variety of models such as Q32SB, Q33SB, Q35SB, Q33B, Q35B, Q38B, Q312B and other main substrates for Q series PLC, and the meaning of the model is as follows: In the meantime, the "S" stands for ultra-thin main substrate, and only Q61SP power modules can be used, and they cannot be ...

When using Modbus communication in Mitsubishi PLCs, it is necessary to understand the address allocation of different register types. The following are the common types of Mitsubishi PLC Modbus addresses and their corresponding functions: 1. Coil Register: ...

1. Use the special crimping pliers for network cable to crimp one end of the cable and the RJ45 crystal head; The other end is connected to the FX2N-485-BD communication template according to the method shown in Figure 1-Figure 3, and the two unused P5S terminals are not connected. 2. Open the panel cover on the left side of the PLC host, and put the FX2N-485-BD communication module ...

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 ...

1. The equipment layer/fieldbus CC-Link equipment layer is a field network that connects PLC and other control equipment, sensors and drive equipment, which is the lowest layer of the entire network system. The CC-Link fieldbus connection greatly reduces the number of wirings and improves the maintainability of the system. Whereas...

The intuitive method refers to the search and analysis of faults based on the external manifestations of Mitsubishi inverter defects without any instruments. The visual method includes an unpowered view and a power-on survey. In the overhaul, the first thing to do is to check without power, that is, to use the human sensory organs (eyes, ears, hands, nose) to check the relevant plug-in.

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. Tension Manipulator Principle - Introduction The tension manipulator can be called the tension manipulator, which is usually used with magnetic particle brake, magnetic particle clutch and tension detector, which is suitable for winding, unwinding, tension control, etc. It also has the so-called manual control function, which generally refers to the fact that human beings can ...

TOKYO, March 25, 2020 – Mitsubishi Electric Corporation (TSE: 6503) today announced that it has developed a new technology that integrates power devices, passives, sensors, and other embedded components on the same substrate and performs the dispensing at 100kW (continuous) power.

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) 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 ...

1. Additional torque The torque that occurs on the motor shaft under additional voltage, extra load is called the extra torque of the motor. 2. Starting torque The torque generated by the motor at the moment when a voltage is applied to the motor in a stopped condition is called the starting torque. The starting torque characterizes the electrical...

(1) Prerequisites Mitsubishi servo motors are able to improve the inertia of the motor by adjusting the gain, so as to adapt to the load, but the Mitsubishi servo motor is able to improve endlessly. Under normal circumstances, it is considered that it can withstand within 10-15 times of the additional inertia of the motor, and Mitsubishi reducer is required to be added in addition. We know ...

In the case of impact loads such as electric welding machines, electric arc furnaces, rolling mills, etc., the voltage often flickers; In a workshop, when there are multiple Mitsubishi inverters and other capacitive rectifier loads working, the harmonics that occur are very serious pollution about the quality of the power grid, and there is also considerable damage to the equipment itself.

Press the "SET" button to end the factory setting. Defects usually occur due to problems with the resistors or wiring of the voltage detection loop, rather than the actual undervoltage of the input voltage. OC disadvantages of the A200 series ...

The main content of the protection and maintenance of Mitsubishi PLC Although the failure rate of PLC is very low, the control system composed of PLC can operate stably and reliably for a long time, and it is essential to protect and view it alone. Generally, every six months ...
