Mitsubishi PLC main maintenance and overhaul content points

1. Error message: NO ERROR--No abnormal error occurs Abnormal content and cause: No abnormal occurrence Solution: Check whether the cable connection between the host and the I/O expansion base/module is normal 2. Error message: ...

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. ...

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 the aborted condition is called the starting torque. The starting torque characterizes the electrical...

(1) Arbitrary axis AC command (G140) G140 Instruction Address = Axis Address Instruction Address = Axis Address ... ; Command Address: Arbitrary Axis AC Command (G140) After that, specify the 1-character address set by the parameter (#12071-#12078) to be used for moving commands, etc.

[Example] a motor is equipped with an optical encoder (the optical encoder is coaxially installed with the motor), and the FX2N-32MT is used to measure the speed of the motor. 【Solution】 Because the photoelectric encoder is coaxially installed with the motor, the ...

First, the control accuracy is different The step angle of the two-phase hybrid stepper motor is generally 1.8° and 0.9°, and the step angle of the five-phase hybrid stepper motor is generally 0.72° and 0.36°. There are also some high-performance stepper motors with smaller step angles after subdivision. Communicate the control of servo motor ...

When the FR-CS80 inverter detects an abnormality, it will display an error message or alarm in the operation panel according to the abnormal content, or maintain the function action and block the output of the inverter. When maintaining a function operation, please deal with the cause of its operation before resetting the inverter, and then start working. ...

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 ...

TOKYO, March 30, 2020 – Mitsubishi Electric Corporation (Tokyo: 6503) announced today that it has been appointed by the Japan Aerospace Agency (JAXA) as the contractor for the Global Satellite Observing Satellite for the Greenhouse Gas and Water Cycle (GOSAT-GW), the third satellite in the GOSAT series, ...

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 ...

1. Enter the wiring (1) The input wiring should generally not exceed 30 meters. However, if the environmental disturbance is small and the voltage drop is not large, the input wiring can be appropriately longer. (2) The input/output lines cannot be separated by the same cable, and the input/output lines should be separated. (3) As far as possible, choose normally open ...

Generally, there are three types of Mitsubishi PLC output circuit methods, namely: relay output type, transistor output type and thyristor output type. So what are the characteristics of each of them? First, the relay output circuit Use of relays ...

(1) Ladder diagram Programming language is traditionally called a ladder diagram. The ladder diagram follows the method of relay control circuit, and it can also be said that the ladder programming language is simplified from the symbol evolution on the basis of the logic control of relays and contactors commonly used in electrical control systems.

1. Self-locking and interlocking circuits 1) Self-locking circuit: The self-locking circuit is often used for the start-stop control of the motor. Press the start button X0 motor to start running, release the start button to keep the motor running, press the stop button X1 motor to stop running. 2) Interlock ...

Mitsubishi PLC's Memory is a memory device in the measurement muscle system that is used to store processes and data. The overall information in the measuring machine, including the output of the original data, the measuring machine process, the central operating cut-off and the final operating cut-off are stored in the memory. It is based on the controller ...

Tablet PC can often be seen in today's daily life, it can be brought stronger, but also more popular with us, industrial tablet PC is gradually widespread, because industrial use will cause Tablet PC is very simple damage, so generally will use maintenance covers, so ...

1. The digital-to-analog converter is a system that converts digital signals into imitation signals, which can generally be completed by low-pass filtering. The digital signal is decoded in the first line, that is, the digital code is converted into the corresponding level to form a stepped signal, and then the low-pass filter is carried out. According to the signal and system ...

The tension controller can be called the tension manipulator, which is generally equipped with magnetic powder brake, magnetic particle clutch and tension detector, and is suitable for winding, unwinding, tension control, etc. It also has the so-called manual control function, which generally refers to the ability to give a certain amount of output through the tension manipulator ...

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.

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 ...
