Introduction to the basic application of Delta inverter

1. Programmable manipulator AH series Delta's AH series modular controllers provide automation system solutions for high-end applications. The AH series adopts a comprehensive modular design, and on the basis of Delta's research and development skills, it has developed ...

In order to ensure the reliability of production, when Delta's inverter is planned to be equipped with power drive, in addition to meeting the power drive requirements, the remaining torque increases the consumption of active power. When using cost-effective Delta inverters to regulate the speed, if the flow requirements are reduced, by reducing the rotation of the pump or fan...

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...

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

Delta inverter is a device that converts the power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize the variable speed operation of the motor.

In view of the rapid transformation of the industry, Delta has specially proposed a total linear motor solution, deploying various communication interfaces, extending the evolved model ASDA-A2R from ASDA-A2 as a linear horse driver, and deploying Delta's high-speed bus controller and axis card to form a complete linear motor ...

What are the benefits of inverter power correction? Many brands of inverter power boards, driver boards, and motherboards can be universal, as long as the type, volume, and hardware are the same, and the desired power and voltage value can be obtained by correcting the manufacturer's parameters.

1. The touch screen is controlled by PLC inverter 1. Now the general control of the inverter needs to use PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC in order to complete the control of the inverter to start, stop, and monitor the operation of the inverter.

(1) Considering that the power supply is inconsistent at the time of power-on, the load is short-circuited, and the rational load may present a reverse voltage, the output end of each power supply connected in series should be set up with two anti-parallel tubes, and the forward additional current of the two * tubes should not be less than the additional output current of the power supply, and the reverse breakdown voltage should not be less than ...

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: ...

Delta's programmable controllers, also known as Delta programmables, delta programmable controllers, delta programmable controllers, etc., are electronic devices specially designed by Delta for the industrial automation category to complete digital operations. Delta's PLC uses programmable memory to store execution logic inside it.

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 ...

1. Record the operation data and shortcomings of the Delta: The operation data of the Delta inverter and the motor should be recorded every day, including the output frequency, output current, output voltage, DC voltage inside the inverter, radiator temperature and other parameters, and compare them with reasonable data, so as to facilitate early detection of defects.

Delta's inverters should be thoroughly inspected for the first time or after long-term installation. The items and methods of inspection are as follows: 1) Check whether the Delta inverter is damaged, whether the metal parts are rusty, and whether there is frost. If there is frost and condensation, it should be dried for 4 hours (60°C) or ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube character beginning flash, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again The appearance back ...

1：VFD-EL，VFD-S，VFD-L，VFD-C200 Voltage 220V, 380V, power scale 100W-7.5kw The above series are Delta's simple inverters, commonly known as economical inverters, which are used for small fans and pumps, conveyor belts on food and pharmaceutical machinery, etc., and are used for abbreviated ...

(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.

After the inverter is installed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before the power is not turned on, ensure that there is no short circuit, and then turn on the working power supply of the inverter.

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 ...
