How Mitsubishi PLC works

Mitsubishi CPU module engineering creation method Start engineering tools, create projects. [Establishment process] 1. Select the CPU module to be used in the "Model" item. In the "Programming Language" project, select ...

1. Characteristics of the output reactor: 1. It is suitable for reactive power compensation and harmonic control 2. The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and output harmonic current according to the press; 3. ** Ground protection of Mitsubishi inverter and improved power factor, can block from the grid ...

In the MR Configurator2 servo commissioning software, Mitsubishi has developed a "one-button adjustment" function to solve the problem of rigid noise of servo motors, as follows: 1. Set PA08 to 0003 and adjust the gain to ...

TOKYO, February 21, 2020 – Mitsubishi Electric Corporation (TOKYO:6503) announced today that it has been appointed by the Japan Aeronautics and Astronautics Agency (JAXA) as the contractor for the Mars Lunar Probe (MMX) space probe. Mitsubishi Electric has launched development activities for the project that will utilize MMX's system ...

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 ...

You can use two commands: TWR (Time Write) command and TRD (FNC166) TRD(P) command to adjust the built-in time. 1. TWR (Time Write) command Instructions to write time presets to the built-in real-time clock: Clock ...

1. If you want to use the inverter to drive the motor with a capacitor to improve the power factor, but the motor does not move, please explain the reason. The current flowing into the inverter is used to improve the power factor, but the capacitor cannot be started because its charging current causes the inverter overcurrent (OCT), as a countermeasure, ...

Discrete control and motion control, Mitsubishi's instructions are abundant, there are dedicated positioning instructions, control servo and stepping are easy to complete, to complete some messy action control is also Mitsubishi's strength, and Siemens is weaker in this area, there is no special instruction, do servo or step positioning control is not ...

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 ...

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. 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 is adopted, and the number of wiring is greatly reduced, and the maintainability of the system is improved. Combine...

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 ...

After overhauling and confirming that all connections of the system are accurate, power on the relevant modules until the card indicator is normal. The initiation process of the system after the scheduled repair is as follows: (1) Power supply. Open power supply equipment (including throwing up...

1. If the problem code E.OC1 is displayed on the screen of the Mitsubishi inverter, it means that the overcurrent may speed up the operation when the inverter is accelerating. We need to check whether the output of the inverter is short-circuited and whether the main power supply is operating normally; ...

Press the abort button SB1, the contactor KM coil is de-energized, and the auxiliary normally open contact of the KM connected in parallel with SB2 is disconnected to ensure that the KM coil continues to lose power after the button SB1 is released, and the main contact of the KM connected in series in the motor circuit is continuously disconnected and the motor stops. Auxiliary to the KM in parallel with SB2 ...

Q: When will I choose the E740 series inverter? A: E700 is an economical and small inverter with high driving performance, with the function of holding the brake, and can also add options to expand the function, which can be used for transportation, lifting occupations, and has high cost performance. Q: Mitsubishi inverter E740 should ...

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, ...

The switching quantity control inverter of PLC is selected (that is, the switching output terminal of PLC is directly connected to the switching input terminal of the inverter, and the PLC can control the start, stop, forward and reverse rotation of the inverter and high, medium and low speed multi-stage speed operation through the program). ...

01 USB connection USB connection requires the device USB driver, generally the device will be actively driven after the installation of GX Works2 software, but at a single time due to anti-virus software or system reasons, or the device may not be available, then we need to manually drive the device to the accounting machine. The specific device method is ...

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 ...
