Several factors selection to be determined for VFD(section two)

4) When using high frequency inverter motor, high-speed motor due to electrical resistance, high harmonics increase the output current value is increased. Thus selection for high-speed motor variable frequency drive, its capacity is slightly larger than the selection of ordinary motor.
5) The distance between the drive and the drive motor is generally not more than 50 meters long cable converter if you want to run, this time to take measures to curb the long cable-to-ground coupling capacitance influence, avoid the inverter output is insufficient, so in this way case, the drive capacity of a file to enlarge or at the output of the inverter output reactor installed.
6) AC frequency converter installation site must meet standard environmental requirements, otherwise easily lead to malfunction or shorten life. So for some special applications, such as high temperature, high altitude, the inverter capacity to enlarge a block.
Renda Electric Industrial Co., Ltd. is the leading professional production of low-voltage frequency inverter manufacturer as well as high-tech enterprises, with leading technology and rich management experience and innovative spirit in the field of drive, Renda has maintained a rapid growth, and domestic and foreign customers favor and attention. Inverter product is one of any of the group in 2006 after gradually into the scale electrification products, gradually developed into a company's core products. As production and sales of integrated production and trade enterprises, mainly produces and sells any of five series of products, and gradually establish a low-voltage products and general-purpose three-dimensional structure, to provide users with a satisfactory drive selection scheme and meet different users application requirements.
