INOVANCE (MD 380)

The Inovance MD380 is a series of high-performance alternating current (AC) drives, also known as variable frequency drives (VFDs). It is designed for general-purpose use and functions by employing current vector control to regulate the speed and torque of electric motors.

Key features of the MD380 series include:

1. Motor control: Capable of controlling both AC asynchronous motors and permanent magnet synchronous motors (PMSMs).
2. Vector control: Supports multiple control modes, including sensorless flux vector control (SFVC) and closed-loop vector control (CLVC), which offer excellent low-speed stability and enhanced torque control.
3. Wide voltage range: Available in various voltage classes, including 220 V (single- and three-phase) and 380 V (three-phase), with options extending up to 1,140 V.
4. Programmable functions: The optional MD38PC1 programmable card allows users to write programs in ladder diagram format.
5. Multiple protocols: Supports common communication protocols like Modbus-RTU, PROFIBUS-DP, and CANopen.
6. Advanced software: Comes with background monitoring software that enables parameter upload, download, and real-time oscilloscopes.
7. Enhanced functionality: Built-in features include rapid current limiting, multi-motor switchover, and power dip ride-through functionality.

Common applications

The MD380 series is used for controlling a wide variety of industrial automation equipment. Typical applications include:

1. Textile machinery
