New from Heason Technologies Group is an AC hollow-shaft servo actuator that always knows where it is - in rotation and linear travel, even when gearing is involved - that can be used with various leading manufacturers' controllers.
In addition, Heason says the new Harmonic Drive 'FHA' servo actuator provides better acceleration for fast positioning, compact design, a robust output bearing and high repeatability in a package that helps to save time and design costs whilst increasing motion precision.
It also eliminates manual parameter set-up.
The simplification of the control interface results from incorporating a Hiperface Compatible Sine/Cosine encoder that permits the actuator to be used with a variety of digital servo control systems.
In the past, various different feedback devices have been required to provide control information (e.g commutation, speed, incremental and absolute position).
This innovative development offers a resolution of 4096 revolutions absolute position and 1024 sine/cosine signals per motor revolution.
Further, the Hiperface Compatible Sine/Cosine multi-turn encoder, from Max Stegmann GmbH, minimises cabling effort, cost and failures, and reduces overall actuator length.
The new digital AC hollow-shaft actuators, with ratios from 50:1 to 160:1, are ideally suited for applications in the field of machine tools, printing machines, semi-conductor manufacturing and handling technology.
