The low-voltage fuse cannot be used as an overload maintenance for the motor. It is necessary that the additional voltage of the fuse is greater than or equal to the operating voltage of the distribution line. It is necessary for the additional current of the fuse to be greater than or equal to the additional current of the melt ...

Driven by consumption promotion and product diversification, the manufacturing industry's demand for automation and intelligent promotion in production and processing is also increasing. In the production process, the processing of "large and heavy" items is often difficult to control accurately, and the deviation of orientation is not as easy as that of "small" items. To this end ...

(1) About the synchronous switching function. Now, in addition to the off-line UPS power supply with an additional output power of less than 500VA, the off-line UPS power supply with square wave output is still selected for conversion control without mains synchronization function, and all UPS power supplies with an output power of 1KVA and above are performing the conversion operation of mains power supply to inverter power supply.

Step 1 Two inverters, two wires, and one power supply. Step 2 The inverter wiring defines the two inverters as a master and a slave respectively, the host port 485A is connected to the slave port 485A, and the host port 485B is connected to the slave port 485B. ...

There will be some difference between the parameter setting of the inverter at the factory and the requirements of practical application. Therefore, the reasonable setting of the inverter parameters is directly related to whether the inverter can be used normally, which is of decisive significance. General-purpose inverters generally have dozens or even hundreds of functional parameters.

The ubiquity of AC drives brings significant energy savings to industrial applications. However, the high-frequency switching signal generated by the inverter is easy to form electromagnetic disturbance, which affects the power quality. It is especially significant in occupations with large loads such as lifting and elevators. At this time, the inverter ...

What is the stall prevention function of the inverter? If the given acceleration time is too short, the output frequency of the inverter changes much more than the change of speed, and the inverter will jump due to the flow of overcurrent, and the free operation is stopped, which is stalling. In order to prevent stalling and keep the motor working, ...

This example is an example of the equipment used to connect a Modbubs to Profinet gateway to a Delta inverter, and the equipment used is a Siemens 1200 PLC, a Delta inverter, and a DJI Modbus to Profinet gateway. 1、Mo ...

Delta's servo motor system is planned for industrial use, and it is necessary to have a full understanding of the motor standards and operation manuals before operating the motor. For the safety of the operator and the mechanical equipment, and to ensure that the communication motor can be used correctly, please read this safety precaution before installing the machine. ...

Inverter cabinet is an industrial control equipment that can be widely used in fire fighting, daily constant pressure water supply and drainage, agricultural sprinkler irrigation pipe network pressurization, urban music fountain active water supply control, HVAC cold and hot water circulation control and other occasions. In addition, it also has a variety of maintenance functions such as: short circuit, overload, phase loss, etc.

1. The necessity of braking resistance If the regenerative energy that occurs during deceleration and descent in the application is too large, there is a possibility that the voltage of the main circuit inside the inverter will rise, causing damage. Because usually the inverter has a built-in overvoltage maintenance function, the main circuit overvoltage (O...

As factories move from automation to intelligence, the requirements for equipment performance and scalability are progressing day by day. In response to the rapid development of electronic engineering, transportation and mechanical engineering and other occupations, in order to quickly manufacture related product parts and components, metal coil winding technology is also being carried out at a high speed.

First, the selection of output module The output modules are divided into transistors, triacs, and contact types: (1) The switching speed of the transistor type is fast (generally 0.2ms), but the load can be small, about 0.2-0.3A, 24VDC, suitable for fast switching, signal contact...

Delta's inverter problem 1: Communicate with the motor driver to explore the formation of overvoltage conditions on the internal DC high-voltage power supply side Check whether the keyed operating voltage is in the field of the additional value of the communication motor driver keying operating voltage, and detect whether there is a surge operating voltage formation If it is due to ...

Problem Clarification: Communication Transmission Timeout: The Modbus transmission between the VFD and the Keypad times out Solution: VFD does not respond to Keypad's communication commands. 1. Confirm the communication quality of the communication wiring and contacts. 2. Please use the RESET key to clear the Fault ...

Delta's A2 series servo system is one of the more common and used servers on the market today, and the following describes the fault details of the azimuth controller in the repair of Delta's A2 servo drive and the corresponding repair methods Delta ...

The inverter used in industry is divided into two types: single-phase and three-phase, which is distinguished from the voltage supplied by the main circuit, which is the main circuit to be connected to RST three-phase 380 volt alternating current, and the output is connected to the UVW three-phase line to the motor; And the single-phase is the main circuit connected to the single-phase 220 volt LN alternating current, the output is the same ...

　　After the long-term operation of the industrial tablet, there is a lot of dust in the chassis and the temperature of the chassis is high. At this time, it is very simple to cause the disk failure of the industrial tablet computer, the product quality problems of the hard disk itself and the failure problems caused by the working environment. ...
