Preface
Thank you for purchasing the MD500 Series AC Drive developed by Inovance Technology!
It is a general-purpose and high-performance current vector AC drive technically upgraded from the MD380 se-
ries. It is mainly used for controlling and adjusting the speed and torque of three-phase AC asynchronous mo-
tor. Using high-performance vector control technology, the MD500 Series AC drive features high torque output
at a low speed, excellent dynamic characteristics and superior overload capability. It provides user-program-
mable features and background software monitoring and communication bus functions and supports multiple
encoder types, delivering rich and powerful combined functions and stable performance. It can be used to drive
textile, papermaking, drawing, machine tools, packaging, food, fans, water pump and other automated produc-
tion equipment.
