Inverter dustproof method - Sunland inverter

At present, the domestic air compressor market takes the goal of energy saving, environmental protection and cost reduction as the primary demand, and the new products developed are very popular. However, economically speaking, it cannot completely replace the conventional screw air compressor with large area and large capacity in use. Therefore, the use of inverter technology to ...

Hope Senlan inverter control panel button function diagram 1. The "FUNC/DATA" button is a programming key, press this button once to convert the operation mode, and press it again to read and write the utility code. 2."S ...

1. Connect X (switching input) drive terminal to control the inverter start-stop/forward and reverse rotation; 2. Connect to the AI (analog input) terminal to control the frequency of the inverter (perhaps made into PID closed-loop control active conditioning frequency) 3. Other DO (switching output) is used for transmission ...

In the process of using bearings, often due to some external factors cause some wear in the rotation of the bearing, and these bearing wear will be completely damaged in the addition of day by day, which requires our maintenance personnel to replace the bearing, and generally form a bearing.

The inverter is an essential accessory in industrial use, and its main function is to regulate the speed of the motor. It is widely used in various equipment such as production F-line and machine tools. Many engineering people have touches. The functions of the inverter are many, the parameters are complex, and it is difficult to play without professionals. ...

What happens when the inverter-controlled motor presses the abort button, and the motor is not controlled to speed up? 1. If it is a newly installed inverter, it is generally necessary to consider the wiring problem, you can first change the parameters to switch to the panel control, the panel is given the frequency, and then see if the inverter operation will appear in this ...

The gantry milling machine is a machining equipment for processing larger workpieces, and its electrical control system includes two parts: the main transmission of the workbench and the logical control of the feed organization. Henan Jiaozuo Maike Company has a gantry milling machine, which has been used for many years since the 70s. The main drive of the operating table of the gantry milling machine is selected ...

A frequency converter (VFD) is an electrical energy control device that converts a power supply to another frequency by using the on-off effect of power semiconductor equipment. It can realize the soft start, frequency conversion speed regulation, improved operation accuracy, power factor, overcurrent/overvoltage/overload protection of AC asynchronous motor, etc.

Depending on the cause of overvoltage, the countermeasures adopted are different. Regarding the overvoltage phenomenon that occurs in the parking process, if there is no special requirement for the parking time or direction, then the extension inverter deceleration time or free parking method can be selected to solve it. The so-called free parking ...

Robot contactors are noisy? Cause: It is likely that the joint contact surface of the contactor is uneven, and the surface is sand or rust. The result will constitute a phase loss, which will lead to the burnout of contactors, switch frequency conversion and other components. Solution: will control the ...

1. Preparation process: Abort the device and admit that the motor is completely aborted. Press the stop button on the operator panel to stop the operation. Disconnect the external mains power supply (low-voltage cabinet drawer). Adequate security treatment should be carried out to ensure that it is indeed disconnected and that it does not ...

The operating principle of the inverter determines that it will have a certain disturbance, which may bring EMC (electromagnetic compatibility) problems to the equipment or system, and the inverter, as an electronic device, will also be affected by external electromagnetic disturbance. Below...

How to distinguish where the inverter is wrong? Step 1: Static data checking 1. Check the inverter circuit The red watch rod is received to the P end, and the black watch rod is separated from U, V, and W, and there should be a resistance value of tens of ohms, and the resistance value base of each phase, the same, the opposite should be infinite.

When the inverter current is too large, exceeding the limit value of the inverter, the maintenance circuit will produce action, so that the inverter trips and stops, and the phenomenon of repairing such inverter can be divided into energized ...

In general, there is a problem with the maintenance trip of the VFD. If you look at the faulty code, you can see what kind of fault is causing it. 1. The selection talent of VFD may be too small; Generally, when selecting VFD, it should be about 20% larger than the rated power of the motor, so that when the motor reaches full load...

1. The control accuracy of the vector type is higher than that of the general type. 2. The vector type has a large output torque at low speed, which can make the motor get a larger starting torque, and is suitable for use in the occasion of heavy load starting, such as: high-power long belt, hoist, etc. If it is used in some of the more common fields ...

Investigation of the function of the inverter system Before debugging the inverter, it is necessary to carefully read the instruction manual and related information of the inverter to be debugged to understand the use environment and precautions. Especially before the inverter is energized, it is necessary to carefully investigate and check whether the inverter has obvious problems.

It is hoped that Sunland low-voltage inverter can be divided into four series: 1.HG1000 high-performance light-load intelligent inverter, the most cost-effective, the new series is widely used in medicine, food, packaging, cable, printing and dyeing, washing, centrifuge ...

1. Condensation The temperature difference in the workshop is large, and the inside of the inverter presents condensation. 2. Impact load. The load fluctuates greatly, and the output current of the inverter suddenly increases, resulting in module damage. 3. The inverter is overloaded in the start, ...

It is necessary to separate the signal line from the power line: when using analog signals for long-distance control of the inverter, in order to reduce the disturbance of the analog amount from the inverter and other equipment, please separate the signal line of the control inverter from the strong current circuit (main circuit and sequential control circuit). Inverter ...
