Product Introduction

LSD-J7000 series variable-frequency-drive(VFD) is a high-performance full vector VFD, mainly used to control and adjust the speed of three-phase AC asynchronous motors. The LSD-J7000 series VFD has a built-in ST (STMicroelectronics) 32-bit microprocessor. The algorithm and function are optimized to the greatest extent. This series not only retains the main functions of the LSD-B7000, but also added some functions according to customers' requirements. At the same time, all functional parameters are grouped and designed to reduce the trouble and misoperation of customers when modifying parameters, which greatly increase the operability of the VFD. Also, the design volume of LSD-J7000 series is generally lighter than the same type VFD in the market, and it is more convenient for customers to use.
