Schneider Electric Altivar 71

Schneider Electric Altivar 71 is series of heavy duty drives for speed control of asynchronous motors  (3 phases). Power range of motors is 0,37 … 630 kW.  ATV71 is intended for simple production mechanisms in different fields of industry.  The series of Altivar 71 frequency inverters meets the all exacting requirements of use due to the various laws of motor control and plentiful functional possibilities. They are adapted for solving the most complex problems of electric drive:
- improved accuracy during work on very low speed;
- perfected dynamic characteristics with vector control flow algorithms (CVF) in open-loop or closed-loop drive system;
- extended the output frequency range for engines with high speed;
- precision of maintenance of speed and energy-savings for open drive with synchronous motor;
- smooth, unstressed control of unbalanced mechanisms by the power adaptation system (ENA).
- parallel connection of motors and special drives with using of scalar control law;
