500 Variable Frequency AC Drive

500 Variable Frequency AC Drive

The Series 500 variable speed AC drives offer both variable-frequency( V/Hz), sensorless or closed loop vector control. It is mainly used for controlling and adjusting the speed and torque of three-phase AC asynchronous motors. The UNICO Series 500 AC Drive uses vector control technology offering exceptional performance features for optimal torque control at a low speeds, excellent dynamic characteristics, and superior overload capability. It’s user- programmable features and PC monitoring software offers a powerful set of functions and features. This makes the Series 500 extremely powerful across all industries requiring precise AC motor control for textile, papermaking, drawing, machine tools, packaging, food, fans, water pumps and other automated production equipment.
