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 ...

(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. After the inverter is repaired, the power number needs to be corrected, don't forget it Generally, an inverter corresponds to a power number (also known as the number of horsepower), for example, a 75 kilowatt inverter is set under heavy load, and 100 kilowatts is set under light load. In this way, the customer will not use it to present ...

The main way to use the inverter is to change the output frequency to achieve the controllability of the motor speed, so do you know what steps are required to complete the output frequency controllability? One of the main points is how to complete the change of the frequency signal supplied by the inverter equipment.

1. Control mode: i.e. speed control, torque control, PID control or other methods. After the control method is adopted, static or dynamic identification should generally be carried out according to the control accuracy. 2. Minimum operating frequency: That is, the minimum speed of the motor. When the motor is working at low speed, the ...

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.

PLC progressive scanning standard work preparation. Abundant programming language: instruction statements; ladder diagram; SFC。 Abundant instruction statements: 45 instruction varieties, including 28 root instructions and 17 usage instructions. 350 step law capacity. uS-level root directives ...

We really talked a lot about the relevant knowledge of inverter repair, but we talked less about the main reasons for protecting the main power supply circuit. Then take a look at the introduction below: When there is a fault in the main power supply circuit of the inverter, in addition to selecting each component to match the corresponding power, it should also ...

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. ...

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 ...

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.

In the case of low speed accuracy requirements or small load changes, the inverter can be selected. The U/f control method refers to the method of controlling the frequency and voltage of the inverter. The rotational speed change in this control method is done by changing the set value of the frequency. ...

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 ...

DC governor is a kind of motor speed regulation equipment, including motor DC governor, pulse width DC governor, thyristor DC governor, etc. Generally, it is a modular DC motor governor, which integrates power supply, control and drive circuits, selects three-dimensional structure layout, and selects micro-power consumption elements for control circuits.

Daily inspection item 1 of Delta's inverter problem repair: Check whether there are any abnormal changes in the sound of the motor during operation, including whether there is vibration during the operation of the motor. Routine inspection item 2 of Delta inverter problem repair: Check out the inverter installation environment is ...

1) When taking out or placing the servo motor, it is not possible to only pull the wire and drag the motor or only hold the rotating shaft core. 2) Do not hit the shaft directly, e.g. by tapping or hammering, as this may cause damage to the shaft and the encoder attached to the opposite side of the shaft. 3) Give the shaft core ...

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 ...

Question 1. Why use a VFD to control the motor? Speaking of this question, let's first take a brief look at these two devices. The motor is a rational load, which hinders the change of current, and a large change in current will occur when it is started. VFD, which is actually made up of a rectifier inverter circuit, ...

The capacity selection of the inverter is based on the rated power of the motor Myth: The capacity selection of the inverter is based on the rated power of the motor Compared with the motor, the price of the frequency converter is the most expensive, so under the premise of ensuring safe and reliable operation, the frequency conversion can be reasonably reduced.
