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.
