Schneider Electric ATV71HD30N4

Variable speed drive ATV71

OVERVIEW

Thanks to the use of a variety of motor control laws and numerous functional possibilities, the Altivar 71 frequency inverters comply with the most stringent application requirements.

This series is adapted to solve the most complex tasks of the electric drive:

• torque and increased accuracy when operating at very low speeds and improved dynamic characteristics with vector flow control algorithms in an open or closed drive system;
• extended output frequency range for high-speed engines;
• parallel switching of engines and special drives using the scalar control law;
• accuracy of maintaining speed and energy saving for an open drive with a synchronous motor;
• smooth, shockless control of unbalanced mechanisms using the Energy Adaptation System (ENA).

With the expansion of the power supply range to 690 V, the multi-functionality of the Altivar 71 increases the productivity and flexibility of using machines for numerous applications.
