Mitsubishi PLC communication detection steps

The models of QnUDVCPU series products are Q03UDVCPU, Q04UDVCPU, Q06UDVCPU, Q13UDVCPU, and Q26UDVCPU. Data logging settings can be written to the target memory of the Mitsubishi QnUDVCPU module. When writing data recording settings, you should write data in the purpose of the writing settings.

Step Instruction (STL) is an instruction that uses internal software components to control the process step on top of the sequential control program. A step-to-back instruction (RET) is an instruction that is used to return to the main program (bus) after the state (S) process is completed. ...

1. FX series programmer The programmer is an important peripheral device of the PLC, which is used to write the user program to the PLC user program memory. On the one hand, it can be programmed by the PLC, and on the other hand, it can monitor the working status of the PLC. With the development of PLC skills, the multi-...

1. Occasions to choose a servo motor with brakes: The servo motor is mainly loaded through the motor shaft, if the load driven by the motor shaft is in the straight direction, after the whole control system is powered off, the load on the servo motor shaft will be driven to run down under the effect of gravity, so that ...

Each element of the Mitsubishi FX2N series PLC is indicated by a characteristic letter, such as X indicates the input relay, Y indicates the output relay, M indicates the auxiliary relay, T indicates the timer, C indicates the condition element, etc., and these elements have a specified number. ...

1. The ERR problem is an under-voltage problem, which is usually caused by the problem of voltage detection loop resistance or wiring, rather than the actual input voltage showing undervoltage. Most of the OC problems of the A200 series are caused by the damage of the drive circuit, and its drive circuit ...

1. Step Instruction (STL/RET) Step instruction is an instruction that is specially planned for sequential control. In the field of industrial control, many control processes can be completed by sequential control, and the use of step instructions to complete sequential control is not only convenient to complete, but also easy to read and modify. There are two in the FX2N ...

Mitsubishi Electric IGBT is the English word Insulated Gate Bipolar Transistor, which means insulated gate bipolar transistor in Chinese. Functionally, IGBT is a circuit switch, and the advantage is that it uses electricity.

(1) Aging of the drive circuit Due to the use of a long period of time, it will inevitably lead to the aging of components, which will cause the drive waveform to be distorted, and the output voltage will be unstable, so OC alarm will often appear as soon as it is running. ( ...

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 ...

Generally, asynchronous motors are planned according to constant frequency and constant voltage, and it is impossible to completely adapt to the requirements of frequency conversion speed regulation. The following is the influence of the inverter on the motor: Regardless of the form of the inverter, the building automation training device operates ...

When calculating the electronic gear ratio of the Mitsubishi servo motor, the first thing to pay attention to is to check whether your Mitsubishi servo motor has been directly set to XX pulse one turn, if this parameter is not directly set, we can go through a simple formula to calculate the electronic gear ratio of the Mitsubishi servo motor. ...

Control requirements: press and hold the forward rotation button, the servo motor rotates forward, release the forward rotation button, and the servo motor aborts the work. Press and hold the rotary button, the servo motor rotates, release the rotary button, and the servo motor aborts the work. When turning forward, pressing the turn button has no effect. When turning, pressing the forward turn button is invalid ...

When evaluating which process is suitable for which approach in the production environment, consider the problem you want to solve and consider all the costs that the robot can save: reduce waste, improve efficiency, improve productivity, improve safety, or reduce labor costs. These costs ...

There are several ways to classify Mitsubishi inverters: According to the classification of the main circuit operation method, it can be divided into voltage-type inverter and current-type inverter; According to the classification of switching methods, it can be divided into PAM control inverter, PWM control inverter and high carrier frequency PWM control inverter; Depend on...

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. 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 ...

1. Speak before you start With regard to defective electrical equipment, it is necessary not to rush to start, but to inquire about the passage and defective phenomena that cause defects. For unfamiliar equipment, you should also understand the circuit principle and structural characteristics, and follow the corresponding rules. Before dismantling, it is necessary to fully understand each electrical department ...

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, ...
