General Overview Drive Overview Dowanload Catalog

SieiDrive – XVy-EV series servodrives offer advanced technology for drives used in Motion Control applications, their high-bandwidth, powerful DSP and highly reliable power stage allows the drives to provide excellent control for a vast range of brushless servomotors and asyncronous motors.

XVy–EV implements next generation functions as a standard, to perfectly meet the most advanced architectures of the most modern industrial servo systems.

The integration in the drive of dedicated application software programs allows for unique customisations, to suit specific controls of complex machineries in sectors such as: working machineries for plastic material, sheet metal, textiles, wood, marble and printing presses, as well as in the most advanced automation solutions.

Flexible and powerful, XVy-EV can offer two programming modes for the intuitive implementation of both simple architectures and complex control systems.
