Causes and solutions of inverter skipping current faults - Senlan

Natural heat dissipation methods are generally used for heat dissipation of small-capacity inverters, because their operating environment should be well ventilated and free of dust and floating objects. The dragging objects of this type of inverter are mostly household air conditioners, CNC machine tools, etc., and the power is small. ​ ...

In order to ensure the safe, efficient and reliable operation of the inverter, the following keys should be grasped when using the inverter: 1) It is necessary to reliably ground the grounding terminal of the inverter, so as to effectively press the radio frequency disturbance and enhance the reliability of the system.

1. Wiring of fire emergency lighting Generally, the flame retardant wire is used to wear the metal pipe and the thickness of the protective layer is ≥ 30mm, in the decoration project, when the emergency lighting circuit can only be applied to the ceiling, the heat-resistant or fire-resistant wire should be selected and the fire-resistant and heat-resistant matching should be considered.

The presentation of inverters has brought a revolution to industrial automation control and motor energy saving. Industrial production is simply inseparable from the inverter, even in the daily livelihood, elevators, inverter air conditioning has become a part of the insistence, inverter from the beginning into all corners of production, subsistence. However...

On April 15, 2011, the "Century Tour of China's Automation Industry (CAIE2011)" was held in Beijing, and Sunland inverter was once again re-elected as "China's well-known brand of domestic inverter". Dr. Chen Bin, President of Continental Hope Group and Chairman of Hope Sunland Technology Co., Ltd., personally ...

The digital signal processor is selected, and the work efficiency is higher A good quality two-phase electric fan inverter uses a digital signal processor, which can make the work efficiency higher, that is, it may take 3 hours to complete the work, but now it only takes 2 hours to be able to...

Generally speaking, the inverter will inevitably present some problems during operation, such as oscillation and noise, which are common problems in VFD operations. So, what causes oscillation and noise in VFDs? What is the solution to these problems? Here are the causes of VFD oscillation and noise ...

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 ...

1. The "FUNC/DATA" key is a programming key, press this button once to convert the operation mode, and press it again to read and write the function code; 2. The "SET/>>" button is the display switch and shift key, press this key to switch the display content, and press it again to ...

1. Please explain the maintenance function of the inverter? (1) After detecting the abnormal situation, the correction action will be carried out automatically, such as overcurrent loss rate prevention, regeneration overvoltage stall prevention. (2) After detecting the abnormality, the PWM control signal of the power semiconductor device is closed, so that the motor can park automatically. As...

The rail-rail power supply is a kind of switching power supply that is installed through the rail-type device, which is mainly used to monitor the voltage, current, temperature and other different aspects of the equipment, so that it can play a good maintenance effect. This switching power supply has a variety of different characteristics such as small size and light weight, ...

When various factory equipment uses frequency conversion speed regulation, harmonic disturbances will be generated on the power supply side and motor side of the inverter (VFD), which will cause electromagnetic disturbance to the power supply network and other electrical equipment near the VFD. In addition, in order to ensure the long-term reliable operation of the VFD, the wiring of the VFD is very important. ...

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.

The following four steps are very important for the commissioning of the inverter with the machine (i.e., connected to the motor) and no-load (i.e., the motor without load). (1) Set the power of the motor, the number of pole pairs, and check the operating current of the inverter. （ ...
