Characteristics
The MD520 series AC drive is designed to be a general‑purpose high‑performance
drive featuring rich functions, convenient operations, and aesthetic appearance.
Leveraging the current vector control technology, it precisely controls and regulates
the speed and torque of three‑phase AC asynchronous motors and permanent
magnet synchronous motors. The MD520 is suitable for various industries, such as
cable, machine tool, petrochemical, and natural gas.
Figure 1‑1 Product appearance
The MD520 highlights the following:
●
Drives the three‑phase AC asynchronous motor and permanent magnet
synchronous motor.
●
Enhances drive performance to enable synchronous and asynchronous motors to
deliver 150% torque output at zero speed without an encoder, simplifying the
drive and control process.
●
Addresses technical‑ and performance‑related problems of equipment in
industries such as cables, machine tools, metal products, petrochemicals, natural
gas, lifting, pulping and paper making, textile, printing and dyeing, and ceramics.
●
Supports the VVC algorithm to simplify and stabilize the synchronous motor,
especially at high speed.
●
Inherits functions of the MD500‑PLUS, MD500, MD500E, MD290, and MD330 and be
compatible with MD500‑PLUS options, including PG cards, communication cards,
I/O extension cards, and brackets.
