690+ series

Industrial applications demand drive technologies of different performance levels. Until now, this need was met with different drive types. Simple "Volt/Frequency" control for fans and pumps and "Sensorless Vector" or closed-loop "Flux Vector" for more demanding applications.    SSD - Eurotherm's 690+ AC Drive provides all performance levels from just one product.

Induction motor control is brought to a new performance level by the advanced high bandwidth torque and current control loops used in both sensorless and closed loop vector modes. Full torque at low speeds and robust trip-free response meet the most critical demands of dynamic applications such as web processing, winders, and high speed lifts. 
 
Electronic line shafting between drives for precise phase-lock control can be achieved using a systems board with a second encoder input
