Product informaon

Components of Lenze's automaon system include controllers and a broad porolio of

inverters with matching standard three-phase AC motors, synchronous servo motors and

asynchronous servo motors. The motors can each be combined with gearboxes in various

designs. Decentralized I/O systems and HMIs complete the Lenze automaon system.
