Introduction to the features of Delta's power modules

1. When the Delta inverter breaks down in the future, it is best not to hand it over to someone who has no experience in repairing the inverter to repair the inverter, otherwise it may get worse and worse. Sometimes it's about to fuse, be sure to check whether there is a problem with the module, some electricians have not experienced it, and immediately install a good fast melt (definitely not ...

Inverter is a kind of speed regulation equipment, where is there a place to use motor speed regulation, especially asynchronous motor speed regulation, will use inverter, now it is mainly used in industrial equipment on a large scale, because the motor is the heart of industry, and three-phase asynchronous motor occupies the vast majority of the share, ...

The rapid development of the national economy has opened up a broad shopping mall space for the growth of the civil aviation industry. In order to meet the surge in the number of flights, an international airport in Northwest China has invested in the third phase of the expansion project, and has been listed as the "number one project" for civil aviation development and the "benchmark demonstration project" for national civil aviation.

(1) Ambient temperature: Like other electronic equipment, the inverter has certain requirements for the ambient temperature, which is generally "-10-+40°C". Because the inverter is a high-power electronic equipment, it is very easy to be affected by the working temperature, but in order to ensure the safety of the inverter's work.

1. Ability to adapt to the environment 1.1 Ability to adapt to grid voltage fluctuations When the motor on the bus starts in a group, when the largest motor unit on the bus starts, the influence on the operation of the inverter, which is related to the input voltage fluctuation range parameters promised by the inverter.

Delta was established in 1971 to provide power supply and heat dissipation treatment programs for the world. Over the past 20 years, Delta's development in Chinese mainland has become increasingly deep-rooted, and its business operations cover development, production, sales and service. With innovative skills, we will continue to strengthen engineering research and development equipment and sophisticated testing ...

Those who know more about Delta's automation know that Delta's inverters have two main series: "M300" and "C2000". "Compact Inverter M300 Series": This series has been introduced many times before, including ...

Regarding the grounding problem, it can generally be swept away after the following steps (because most of the inverters are not easy to detect the current measurement of Hall components, it is very important to sweep the grounding caused by external conditions, and alternative methods can be selected if there are conditions, and it is still an external problem to change a normal load to see whether it is a problem of frequency conversion or an external problem ...

Correct installation, operation and maintenance of the reducer is an important part of ensuring the normal operation of mechanical equipment. Therefore, when you install a planetary reducer, it is necessary to carefully assemble and operate it in strict accordance with the following matters related to the operation of the device. ...

In Delta's M series inverters, the parameter address 2000H corresponds to abort, start, JOG, and forward, rotation, and change direction. Why is "aborted" at the time of writing the program H01, "start" is H10, "forward" is H12, and "rotation" is H22. ...

1. Restore the inverter to factory settings, press the "ENTER" button to enter the parameter setting interface, and press it continuously until it is 00-00 and then stop. Press the number up button to change to 00-02. Press the "ENTER" key again, the panel value will show 0, press the number up key to change it to 9. Press the "ENTER" key, break ...

There are many setting parameters of the inverter, each parameter has a certain selection scale, and the inverter can not work normally due to the improper setting of a single parameter is often encountered in the application, therefore, the relevant parameters must be set correctly. ...

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. Due to the built-in overvoltage maintenance function in the inverter, the overvoltage of the main circuit (O ...

If the inverter is to run the equipment again after being shelved for more than half a year, the probability of damage may be greatly increased due to many factors such as the placement environment, the service life of the inverter, and the load rate, and the failure usually presents the following problems: 1. After the equipment is powered on, it becomes ...

1. Parameters to be set for the motor When the inverter (hereafter referred to as the -VFD) is operating in the "vector control" (F0-03=1) mode, it is highly dependent on accurate motor parameters, which is one of the important differences from the "VF controlled" (F0-03=2) mode. In order for the VFD to have outstanding driving ...

1. The external control panel is rotated and operated After selecting the upper or lower button on the panel, the Frd inverter will rotate forward if you select the inverter, and the rEu inverter will rotate 2. The external control terminal is rotated Access via external terminals ...

1. Capacity safety factor The AC regulated power supply is based on the output apparent power (kVA) as the nominal rated capacity, and the load is not purely resistive under normal circumstances, that is, the power factor COS¢≠1, and the active power that the regulator can output in practice kW = capacity (kVA) × COS¢. So in the real ...

Problem Description: What is stall avoidance? Solution(s): If the given acceleration and deceleration time is too short, the output frequency of the inverter changes faster than the motor speed, and the inverter will stop working due to overcurrent, which is called stalling. In order to make the motor ...

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 ...

First, the maintenance of the inverter must first check whether the sound in the operation of the motor is abnormal, including, whether the motor is in operation to form a sensation. ​ 2. Check whether the natural environment of the inverter installation has changed. ...
