The Altivar 71 range of variable speed drives is able to respond to the most exacting requirements thanks to its different types of motor control and numerous onboard functions. It is suitable for the most demanding drives: b Torque and speed accuracy at very low speeds, high dynamics with Flux Vector Control (with or without sensor) b Extended frequency range for high-speed motors b Connection of special motors and drives in parallel thanks to the voltage/frequency ratio b Static speed accuracy and energy savings for synchronous motors in open loop mode b Smooth flexibility for unbalanced machines with the ENA System (Energy Adaptation System) The functionality of the Altivar 71 drive boosts.
