In the PLC control system, the content that needs to be displayed mainly includes timer value, counter value and data register value, and the data display method can be summarized into two fundamental types: one is based on the PLC data communication interface, such as RS-232, RS-485/422, and the display device also has such an interface.

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 ...

Component conversion is a process in which an analog signal (load converter output voltage) input from outside the programmable controller is converted into a digital output value and a total component output value, and then stored in buffer memory. After the conversion process, the conversion completion (XE) will change to ON, and the transformation completion mark (Un\G1 ...

1. Graphical instruction structure: The program is expressed graphically, and the instructions are composed of different graphic symbols, which are easy to understand and remember. In the logic operation part, almost all manufacturers use a ladder diagram similar to the relay control circuit, which is easy to accept. More complex arithmetic operations, ...

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 ...

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 ...

Major Failures and Analysis: 1. Motor encoder alarm 1. The cause of the failure (1) Wrong wiring; (2) electromagnetic interference; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment; 2. Troubleshooting ...

Q: When will I choose the D740 series inverter? A: D700 is a multi-function compact inverter, more portable, less than E700, the general function can be basically realized, simple start and stop can use D700 series. Q: How should Mitsubishi inverter D740 ...

1. For the test of the power output capacity of the driving circuit, to detect the pulse terminal signal such as GU\EU, it is not possible to have voltage (or pulse waveform) alone, and the current output capacity should be detected, and then admit whether it is normal; 2. Admit the defects of the current transformer. My solution is to use the ...

The capacity (non-functional) of the Mitsubishi inverter for the drive motor can be understood from the change in energy flow determined by the operation method. 1. When accelerating or operating at constant speed The efficiency of the inverter is the output current, that is, how much current the inverter can provide to the motor. Frequency converters ...

A lot of data is used in the internal structure of the PLC and in the user's use program. These data have the following forms in terms of structure or number system. (1) Decimal number Decimal numbers are also known as word data in PLC. It is first and foremost ...

1. The workbench runs in the direction of the decrease of the value of the current value register (generally M8342=OFF in the opposite direction), and when it encounters the near-point signal, it becomes a creeping speed, and the zero-point signal after leaving the near-point signal arrives with a delay of 1ms, and the pulse output is immediately aborted. ...

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 ...

First, the control accuracy is different The step angle of the two-phase hybrid Mitsubishi servo motor is generally 1.8 ° and 0.9 °, and the step angle of the five-phase hybrid Mitsubishi servo motor is generally 0.72 ° and 0.36 °. Mitsubishi servo motors are also smaller in some functions according to the segmentation. Such as Sanyo ...

The motor of the core and winding coil is what we commonly see in our daily life, and what is the heating principle of this Mitsubishi servo motor by comparing it with other motors? We know that the winding has resistance, and the loss will occur when energized, and the size of the loss is proportional to the square of the current of the resistance.

TOKYO, March 26, 2020 – Mitsubishi Electric Corporation (TSE: 6503) announced today that it has developed a new technology for efficient design and material flow of production floor layouts and accurate estimates ® of productivity using Mitsubishi Electric's Maisart *AI.

1. The output side of the inverter is short-circuited, such as the connection line between the output end and the motor, or the short circuit inside the motor, etc.; 2. The inverter itself is not working properly, such as the two inverter equipment of the same bridge arm in the inverter bridge are constantly alternating in the working process ...

1. Characteristics of the output reactor: 1. It is suitable for reactive power compensation and harmonic control 2.
