加速時(shí)間過(guò)短。
轉(zhuǎn)矩提升過(guò)高或V/F曲線不合適。

檢查變頻器是否正常工作的方法如下：

檢查變頻器環(huán)境溫度是否正常，要求在-10°C~+40°C范圍內(nèi)，以25℃左右為好。
檢查變頻器在顯示面板上顯示的輸出電流、電壓、頻率等各種數(shù)據(jù)是否正常。
檢查顯示面板上顯示的字符是否清楚，是否缺少字符。
用測(cè)溫儀器檢測(cè)變頻器是否過(guò)熱，是否有異味。
檢查變頻器風(fēng)扇運(yùn)轉(zhuǎn)是否正常，有無(wú)異常，散熱風(fēng)道是否通暢。
檢查變頻器運(yùn)行中是否有故障報(bào)警顯示。

31C075-503-4-00 is SEW frequency converter MOVITRAC 31C075-503-4-00 model, power of 7.5KW, voltage of 380V, power of 4kW, has been tested.
SEW is a German company specializing in the production of all kinds of motors, SEW motors are not only widely used in construction, transmission technology, industry and other fields, but also used in wind power generation, material handling and automation and other fields.

SEW frequency converter is SEW drive, is the German SEW company research and development of frequency converter.
SEW frequency converter has the characteristics of small size, light weight, low noise, high efficiency, easy operation, significant energy saving, simple maintenance, etc., can be widely used in various industrial fields, such as textile machinery, paper making machinery, packaging machinery, plastic machinery, lifting machinery, etc.

When the frequency converter fault code displays E, the possible causes are as follows: 1.

The acceleration time is too short.
The torque increase is too high or the V/F curve is inappropriate.

Check whether the frequency converter works normally as follows:

Check whether the ambient temperature of the inverter is normal, which is required to be in the range of -10°C~+40°C, and about 25 °C is better.
Check whether the output current, voltage, frequency and other data displayed on the display panel of the inverter are normal.
Check that the characters displayed on the display panel are clear and missing.
Use the temperature measuring instrument to detect whether the inverter is overheated and whether there is an odor.
Check whether the inverter fan runs normally, whether there is any abnormality, and whether the heat dissipation duct is smooth.
Check whether there is a fault alarm display in the operation of the inverter.
