MD380 User Manual
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.
The drawings in the manual are sometimes shown without covers or protective guards.
operations in accordance with the instructions.
The drawings in the manual are shown for description only and may not match the product
you purchased.
