1. Error message: NO ERROR--No abnormal error occurs Abnormal content and cause: No abnormal occurrence Solution: Check whether the cable connection between the host and the I/O expansion base/module is normal 2. Error message: ...

1. The speed of the system bus is different. Although the FX5U series is small but precise, compared with the previous product FX3U, the system bus speed is greatly increased by 150 times, and the maximum expansion module can be expanded by 16 intelligent expansion modules, built-in 2-in and 1-out analog functions, built-in Ethernet interface and 4-axis 200kHz high-speed positioning function. ...

01. Base system problem In Mitsubishi PLC, there are binary, octal, decimal, 10, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, remember the binary number from the back, divide every 3 into a group, and each group is converted into octal respectively, such as 1 ...

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, which are also some functions, have a smaller step angle after segmentation. ...

When you are ready to communicate through AJ71QE71, perform the ping procedure in MS-DOS mode to check if the connection is correct before the Mitsubishi PLC's GPPW starts to communicate. Support communication with Weilun touch screen through serial port. Under...

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...

The source type is the power supply of the device, which has an input drive source and an output point with a power supply; Drain type means that the device does not have its own power supply, and the drive of the input point requires an external power supply, and the output is only a passive contact signal. The general input points are ...

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. CC-Link fieldbus connection is selected, the number of wiring is greatly reduced, and the maintainability of the system is improved. Combine...

1. When the PLC and the host computer (or touch screen) form a monitoring system, there are many hours on the screen that require "manual", "active" and other control forms (generally more than one). In the program, you can use the "MOV" command. For example, when selecting "manual", the constant 1 MOV will be changed to a ...

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. Whether there is abnormal change in the sound during the operation of the equipment, including whether there is oscillation during the operation of the motor. 2. Whether the ambient temperature of the inverter installation is too high or too low, the working temperature is generally required to be in the range of -10°C - +40°C, and it is better to be about 25°C. ...

1. DC servo The structure is simple and easy to operate. However, considering the actual operation, the DC servo motor has introduced mechanical equipment for reversing installation, which increases the cost, has many problems, and is inconvenient to maintain, and often interferes with the production and manufacturing due to the sparks of carbon brushes, and electromagnetic interference will occur. Combine...

1. Harmonic disturbance The rectifier circuit will generate a harmonic current, which will cause a voltage drop on the impedance of the power supply system, resulting in a distortion of the voltage wavepattern, and this distorted voltage will cause disturbance to many electronic devices (because most electronic devices can only operate in the sine wave).

The new iQ-F motion module is a controller that can perform advanced motion control such as positioning, synchronization, cam, speed, torque, etc., with a computing cycle of 500μs, and can be connected to a high-function servo amplifier through CC-Link IE TSN, making a higher contribution to the miniaturization and high functionality of the equipment. ...

The three output types of PLC are: transistor output, thyristor output and relay output, what is the difference between these three different output types? (1) Transistor output: The biggest advantage is that it is suitable for high-frequency action, and the sound ...

The main steps in the planning and commissioning of the programmable manipulator application system (1) In-depth understanding and analysis of the process conditions and control requirements of the controlled target a. The controlled target is a controlled mechanical, electrical equipment, production line or ...

1. Use the switching signal of PLC to control 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 SG input ports of the inverter. The PLC can control the inverter through the program.

The main effect of aborting the positioning instruction is that in some machine tools, when we give the abort signal and can walk to the distance we set, for example, if the mechanical structure needs to use the sensor to determine the position to go, you can use the abort positioning instruction to do, when the induction gives the abort.

1. CPU function As a MELSEC IO-F series PLC actuator, it is equipped with executable structured programs and multiple program actuators, and can be written to ST language and FB. 2. Built-in analog input and output (alarm output by the way) Built-in 12-bit 2-channel analog input ...
