(1) When the speed of the motor is controlled by the Delta inverter, the noise and temperature rise of the motor are higher than that of the frequency of the motor. When the motor is running at low speed, because the speed of the motor blades is low, the temperature rise of the motor becomes high.

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.

The inverter of Delta's brand A series locks the keypad to correct the parameters, forming that most of the parameters cannot be corrected, and the manual does not clearly explain how to unlock the keypad lock, press MODE and RESET together to display P256 (P256 does not explain what it means in the manual), press ENTER...

From May 23 to 25, 2019, the Delta Power Electronics Technology Application Seminar, hosted by Delta Group of Zhejiang University, was held at the KONE Hotel in Wujiang, Jiangsu. Experts and professors from the power electronics technology industry from all over the world and 360 teachers, students and practitioners from more than 10 key universities such as Tsinghua University and Zhejiang University.

1. One is a triode type photocoupler, such as PC816, PC817, 4N35, etc., which is commonly used in the output voltage sampling and error voltage amplification circuit of the switching power supply circuit, and is also used in the digital signal input loop of the inverter control terminal. The structure is the simplest, and the input side consists of a light-emitting two...

With the development of electronic semiconductor information technology, technologies such as the Internet of Things, big data, and cloud channels are showing a trend of hundreds of schools of thought, which also drives the rapid development of intelligent production. Intelligent production also puts forward new requirements for controllers: high speed, large capacity, miniaturization, networking...... In order to ...

One is hardware, similar to the CPU reset circuit, which gives the downtube a short high-level drive pulse during the initial power-up, and then the voltage drops to 0 to cut off the downtube. The second is the software, when the CPU is operating normally, it outputs a square wave pulse that only needs to be turned on by the lower three tubes, so that the upper tube ...

The ways to reduce the soft fault of the inverter are: 1. Detect the overvoltage and undervoltage of the inverter; 2. Detecting overcurrent is the most frequent phenomenon of frequency conversion alarm. Generally, the overvoltage alarm is generally presented at the time of shutdown, and the primary reason is that the deceleration time is too short or the braking resistance and braking unit have ...

The first step is type recognition: acknowledging whether the type of inverter is common to the type of inverter purchased. If not, ask the agent to return the item. Step 2: Shipping Acknowledgement: After opening the package, check whether the inverter is damaged during transportation. If there is damage, let the agent return ...

With the continuous development of science and technology, there are more and more types of domestic machinery and equipment, and the upgrading of equipment is getting faster and faster. So what are the characteristics of two-phase electric fan inverter and whether it is worth choosing for enterprises. ...

1. Each VFD should be cleaned and protected once a quarter. Protecting and cleaning equipment must have specific records and the signature of the person in charge. As long as the management is in place, the task can be completed with quality and quantity; 2. Before cleaning, the power supply must be blocked, and the voltage must be reduced to a safe voltage before starting to work. ...

Belt conveyor is a kind of continuous conveyor, which is one of the most important types of stationary or escorted cranes. The belt conveyor is the use of friction to convey the dynamics, with belts, steel belts, steel fiber belts and chemical fiber belts as a kind of adaptation to the transmission of materials and traction operations.

1. When selecting the inverter, select the inverter with the appropriate control method according to the load characteristics In addition to the inverter manufacturing process, it is also important to use the inverter's control method. The control methods of the inverter are mainly divided into two types: open-loop control and closed-loop control. In the meantime, the open-loop control method ...

The motor can be started after the work is completed before use, and attention should be paid to the investigation of the motor, transmission device, production machinery and line voltage and ammeter, if there is an abnormal phenomenon, it should be stopped immediately, the fault should be identified and swept away, and then it can be closed and started again. When the motor is running, ...

1. Before the inverter is energized The temperature and humidity of the surrounding environment should be detected first. Too high a temperature will cause the inverter to overheat the alarm. When severe, it will directly lead to damage to the power supply device of the inverter and short circuit of the circuit; Excessive humidity of the air can lead to a direct short circuit inside the inverter. When the inverter is in operation ...

(1) The harmonic current will directly cause the additional heating of the motor, so that the stator of the motor will exceed the rated temperature rise of the motor itself, so that the rated output capacity of the motor will be greatly reduced. ​ (2) The current wave output of the inverter ...

The selection of the inverter is mainly determined by the load characteristics of the drive and the actual working current of the motor, in addition to the following precautions: 1. The environment is suitable for some high temperature (higher than 50 degrees) and high altitude (higher than 1000 meters).

There are two fundamental circuits for communicating with external signals: analog and digital: 1. 4-20mA current signal loop (imitation); 1 - 5V/0 - 5V voltage signal loop (imitation). 2. Switch signal circuit, inverter start and stop command, forward rotation command, etc.
