The method of Mitsubishi PLC to control the Mitsubishi inverter

Mitsubishi PLC selection - element 1: IO points The number of ZUI IOs that can be accessed by the Mitsubishi PLC control system. Mitsubishi PLC FX series now commonly used basic unit host is: FX1SFX1N, FX1NC, FX2N, FX2NC, FX3U. FX3UCFX3G, FX5U, 9 series. ...

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, ...

If the language is a programming language without any explanation, it will be very difficult for the engineer to understand the program again, and some clarification can bring twice the result to the work. There are three types of explanations: notes, statements, and notes. Note: Explain a certain ...

1、AL. E6 - indicates servo emergency abort. There are generally two reasons for this shortcoming, one is that the 24V power supply of the control circuit is not connected, and the other is that there is no connection between the EMG and SG of the CN1 port. 2. AL.37 - parameter abnormality. The internal parameters are chaotic, and the operator may set the parameters by mistake or drive ...

1. TWR (Time Write) command Write the time preset value to the built-in real-time clock: Clock information is written to the TWR (Time Write) command. The sequence number of the action instruction is FNC167, [S ·] T, C and D can be used, and only 16-bit operations can be used, accounting for 5 program steps. The work of the directive ...

The processor performance test should be carried out in accordance with the requirements of the system manual, to ensure that the system has the function described in the manual, and is stable and reliable, including the system communication, backup battery and other special modules to view. Redundancy testing is necessary for systems with redundant equipment. i.e. the redundant design ...

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. ...

Features of the output reactor: 1. It is suitable for reactive power compensation and harmonic management 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. Effectively maintain Mitsubishi inverters and improve the power factor, which can thwart the ...

The difference between PLC and single-chip microcomputer: 1. PLC is a relatively sophisticated control system composed of single-chip microcomputer, and it is a product of the sophisticated and stable single-chip microcomputer application system that has been debugged. There is strong versatility. 2. The single-chip microcomputer can constitute a variety of application systems, and the scale of application ...

1. Control the start, stop, speed and so on of the servo motor; 2. Carry out various maintenance on the motor (overload, short circuit, undervoltage, etc.) 3. Respond to external signals, and control the servo motor (position, speed, torque) after internal PID conditioning; The manipulator is the control of the electric ...

Mitsubishi Electric's fresh air system realizes indoor ventilation, but of course, we can't just be limited to simply replacing the outdoor air into the room, a good fresh air should filter the harmful substances in the air, so that the air entering the room is not only fresh, but also clean and harmless. ...

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 ...

The encryption process is as follows: ** Open the serial port for the first time [00000000] IOCTL_SERIAL_SET_BAUD_RATE Baud Rate: 9600 (Set baud rate here) [00000000] IOCTL_SERIAL_SET_LIN ...

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. ...

(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. ( ...

It has become an irreversible trend to drive the motor through the inverter, and in the actual application process, because the matching relationship between the inverter and the motor is not very reasonable, it often leads to some problems. When selecting an inverter, you should fully understand the load characteristics of the equipment driven by the inverter. Ms. Ginseng ...

The inverter is the control equipment for the operation of the motor, and it has a certain maintenance function for the motor. Most of the inverter appliances have functions such as overvoltage, overcurrent, undervoltage and overload maintenance. Overcurrent maintenance function. In any link of motor acceleration, deceleration and constant speed operation, ...

Because the output voltage of the inverter (Variable-frequency Drive, VFD) is generally 380 volts, there should be no problem in direct measurement, but in practice, most multimeters cannot get a correct reading when testing the output voltage of VFD, and in some cases the multimeter may be burned directly. ...

When the battery voltage drops, the power supply is "ON", and the "BATT. V" LED lights up, and the battery is valid for one month from the time the light is on. However, there are times when it is found late, so after finding that the indicator light is on, the battery should be replaced as soon as possible to avoid power failure. ...

Introduction to the names and effects of capacitors in different circuits 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 names, understand ...
