Preface
Thank you for purchasing the MD380 series AC drive developed by Inovance.
The MD380 series AC drive is a general-purpose high-performance current vector control AC
drive and is mainly used to control and regulate the speed of three-phase AC asynchronous
motor. It adopts advanced vector control technology and has low-speed high-torque output,
good dynamc feature and strong overload capacity. It increases the user programmable
function, background monitoring software and communication bus function, and supports
multi-kind PG cards. It is used to drive various automation production equipment involving
textile, paper-making, wiredrawing, machine tool, packing, food, fan and pump.
This manual describes the correct use of the MD380 series AC drive, including selection,
parameter setting, commissioning, maintenance & inspection. Before using the AC drive,
read this manual carefully to have a thorough understanding of the product. Keep the
manual well and forward it with the product to end users.
