1.1 Features
The MD500‑PLUS series AC drive is a general‑purpose high‑performance current
vector AC drive used to control the speed and torque of three‑phase AC asynchronous
motors and three‑phase AC permanent magnet motors.
Figure 1‑1 Appearance
The AC drive is armed with the following features:
1. Drives three‑phase AC asynchronous motors and three‑phase AC permanent
magnet motors.
2. 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.
3. Integrated with tension control process to keep a constant tension when the roll
diameter changes, which is widely applied in winding and unwinding of wire
drawing machines, coating machines, printers, and papermaking machines.
4. Integrated with VVC algorithm to simplify and stabilize synchronous motor control
in high speed applications.
