Preface MD280/MD280N User Manual
II
MD280 series inverter is a genenral-purpose and multi-functional inverter
developed by Inovance, which is based on the successful launching of
MD300/MD320 and with the power-drive platform of MD300/320 that is has
already been widely verified, as well as via the market research and
customer demands.The entire system of MD series inverter has
independent ventilation, which can be installed outside or inside the
radiator cabinet,it can provide solutions to IP54 protection
requirements,directly input DC bus terminal and DC powered fan that
enable the standard products to be compatible with the DC bus running
mode, perfect user password protection, shortcut menu design that makes
the complex commission easier, reliable and safe.
MD280 series basic configuration and function are as follows:
I/O terminal
Five D1(DI can be selected as high-speed input port)
2×AI (AI2 can be selected as voltage or current input as
well as keyboard potentiometer reference.)
2×DO

V/FMode Linear V/F, Multi-point V/F, and Square V/F
MD280 series inverter has either built-in keyboard or external keyboard
connecting to the operational panel via the standard RJ45 interface (once
external keyboard is connected successfully, the built-in keyboard display
will disappear automatically, and vice versa), facilitating the commissioning
operation. All these features reflect the “Customer First” principle during the
process of designing MD series inverters.
