Advantages of Mitsubishi inverter installation reactor

Type: FR-E024-0.75K Fault: The boot cannot be started Maintenance: This machine does not provide any symptom information, and the display screen shows an "E.THT" error when the motor is to be started after powering on. Check the instructions refer to the ...

1. Hardware (1) I/O channeling, the PLC automatically detects the I/O fault and enters the STOP mode. (2) The I/O is damaged, and the program runs to the response signal that needs the I/O, and cannot execute the instruction downward. (3) Expansion module (functional, such as A/D) ...

1. If the PLC stops in the middle of some outputs where the output is excited, then look for the signal that caused the next operation (input, timer, line, drum manipulator, etc.). The programmer will show the ON/OFF status of that signal. ...

1. Consultation question: FR-A700 series Mitsubishi inverter, the suffix is ending in -CA1, what kind of inverter? Solution: The suffix -CA1 is a special model with take-up control. 2. Consultation question: FR-A ...

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...

1. Torque control: Torque control is based on external simulation imitation type or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. Assuming that the load on the motor shaft is less than 2.5Nm, then ...

When the inverter is used to form an active control system for control, in many cases, the PLC and the inverter are used together, and how to correctly connect the PLC and the inverter together has become the key to the success of the system. 1. PLC switch command signal input Inverter input ...

The wiring diagram steps of the input and output circuit of Mitsubishi PLC, there are generally three types in the wiring diagram of the input and output of the PLC, one is DC 12-24V input, and there is output, so what about the external input? （1 ...

What is the reason why the programming software on the computer and the Mitsubishi PLC cannot communicate? How do I set the port of the communication line? There are several reasons why communication may not be available: 1. It may be that the PLC is not energized; 2. Programming software to create ...

Capacitor is a kind of energy storage element, with the characteristics of "straight through AC, low frequency through high frequency", people in order to know and identify the capacitor in different circuits, according to its effect in the line and give it many titles, the following introduces the meaning of some commonly used titles. ...

When carrying out anti-disturbance planning for specific projects, it is necessary to select products with high anti-disturbance ability, and adopt methods such as pressing the disturbance source, cutting off or attenuating the propagation path of electromagnetic disturbance, and using software means to improve the anti-disturbance ability of equipment and systems. ...

1. The actual output waveform of the inverter is PWM wave, which contains carrier signals in addition to the fundamental wave. The carrier signal frequency is much higher than that of the fundamental wave, and it is a square wave signal, which contains a lot of higher harmonics, and the test system requires a higher sampling frequency and bandwidth. ...

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, ...

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, ...

First, the frequency converter should not be installed on the equipment with a sensation, because the main circuit connection screw in the frequency converter is simply loose, and many frequency converters are damaged due to this reason. Second, the wiring problem: the input end of the inverter is connected to an air The initial maintenance current should not be too large, ...

Mitsubishi inverter OC (overcurrent problem) will be caused by the following reasons, taking A500 series inverter as an example: 1). Caused by improper parameter setting problems, such as time setting is too short. 2）. ...

1. The switching signal of PLC controls the inverter The output point and COM point of the PLC (MR type or MT type) are directly connected to the STF (forward engine), RH (high speed), RM (medium speed), RL (low speed), and input SG ports of the inverter. The PLC can be programmed to control the inverter's start, ...

The servo system is an automatic control system that enables the output of the object's orientation, direction, and state to change with the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system.

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 ...

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...
