IOP320美卓DCS卡件METSO控制器，變頻器實時控制三相異步電機的轉速，電機帶動造波器的漿液片打擊水面，電機的轉速不同，造成兩個波頭之間的波程和波峰的不同，這樣，三相異步電機不同的轉速與不同的波頭、波程、波峰相對應。

In daily use, due to the complex application environment, component damage and so on, it is possible to cause the problem of no output power after power on, so that the post-stage circuit can not work normally. So what are the common causes?

There are lightning strikes, surges or voltage spikes at the input end

Checking scheme: check whether the front-end fuse, rectifier bridge, plug-in resistor and other components of the input products are damaged, and use differential test to analyze the electrical waveform. It is recommended to be used in the environment in accordance with the EMS conditions of the technical manual. If it is needed to be used in more severe environment, it is necessary to add EMC filter and anti-surge device in the front end of the product.

Input voltage far exceeds the maximum specification value of the product

Checking scheme: check whether the product input fuse, plug-in resistor, large capacitor and other devices are intact, and test the input voltage waveform for judgment. It is recommended to adjust the input voltage, use the power supply with the appropriate voltage as the input, or replace it with a product with a higher input.
