Basic parameter setting of special inverter for wind turbine - Delta

The low voltage of the inverter mainly refers to the low voltage of the central DC circuit, and the reasons for the low voltage of the central DC circuit generally come from two aspects: ​ (1) Low voltage from the input side of the power supply The power supply under normal conditions ...

When selecting a Delta servo motor, in principle, the selection should be based on the load conditions. There are two types of loads on the motor shaft, namely damping torque and inertial load. Both loads should be calculated correctly and their values should meet the following criteria: 　　1) When the machine is running with no load, in the whole speed range, Delta ...

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 ...

Inverter is a high-tech product, mainly composed of power electronic equipment and microelectronic equipment. The three-phase communication grid is connected to the input of the frequency converter. The input end of the inverter is a rectifier circuit, and the output end is a frequency conversion circuit. As a result, the voltages and currents on the input and output sides include abundant ...

(1) The wiring interval between the braking unit and the inverter, as well as between the braking unit and the braking resistor, should be as short as possible (the wire length should be less than 2m), and the wire cross-section should meet the requirements of the braking resistor discharge current. (2) The brake unit is working ...

1. Harmonic problems The equipment that plays the role of switching in the main circuit of the inverter must generate harmonics in the process of turning on and off the circuit. The lower harmonics generally have a greater impact on the motor load and cause torque ripple; The higher harmonics increase the leakage current of the inverter's output cable, making ...

1) Brief planning. Only one battery module, paired with several discrete components, is able to obtain a battery. 2) Shorten the development cycle. It is generally equipped with a variety of input, output, and battery module options. Users are also able to repeat or cross-stack, combined with modular batteries, to complete multi-channel ...

1. Open-loop control There is no reverse connection between the controller and the controlled target, and the control is carried out in one direction. Strengths: Simple, stable and reliable. If the characteristics and parameter values of the components that make up the system are relatively stable, and the external disturbance is small, the open-loop control energy Enough...

In order to ensure the reliability of production, all kinds of production machinery are designed with power drive, and there is a certain surplus when designing and matching power drive. When the motor cannot operate at full load, in addition to reaching the power drive requirements, the residual torque increases ...

Delta's touch screen consists of a contact detection component and a touch screen controller. The contact detection component is installed in front of the display screen to detect the user's contact orientation and is sent back to the touch screen controller; And Delta's touch screen controller's ...

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 error of orientation is not as easy as that of "small" items. To this end ...

1. To switch the motor of the power frequency, the parking method is set to free parking, and it is important not to park softly 2. Intercept the contactor of the motor from the output end of the inverter, and the control stop button and the inverter parking button are the same composite button, that is, when the inverter is pressed, the inverter parking will be followed by the contactor line.

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.

Programming equipment: simple programmer, most only accept mnemonic programming, and some can also be programmed graphically (such as Japan's Toshiba EX programmable controller). The cluttered one has a graphical programmer, which can be programmed in the trapezoidal language. Some also have dedicated computers that can be used for other ...

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 ...

The thermometer method and resistance method can be used to measure the temperature rise of each part of the reducer. 1) Thermometer method: This is the easiest way to measure the temperature directly, and it is commonly measured by an alcohol thermometer. When measuring, the thermometer can be placed close to the ...

The role of the "communication input reactor" of the inverter input device is mainly to improve the power factor of the communication power supply on the communication side of the input side; It is useful to eliminate the higher harmonics on the input side to avoid damage to other electrical equipment caused by voltage distortion; Eliminate the three-phase AC power phase ...

All electronic equipment (including frequency converters) will generate some high-frequency or low-frequency noise during normal operation, and disturb the peripheral equipment through conduction or radiation. If the right EMC filter can be configured and the correct device method can be used, the disturbance can be reduced to a minimum. ...

Outstanding drive characteristics The overload capacity is up to 150% / 60 seconds, 200% / 3 seconds, suitable for constant torque, variable torque, constant power and other loads Support induction motor, permanent magnet synchronous motor, optional PG card for high ...

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 ...
