Users of machine tools, robots and general automation technology are constantly demanding solutions that are high in performance and low in cost. The response to this are dynamic, compact and energy-efficient drives with safety functions. Due to the differing requirements of the individual applications, functionally safe encoders are needed both for the high-end range of machine tool drives as well as for standard applications. With the series launch of the third generation of bearing¬less rotary encoders of the ECI/EQI 1100 series with inductive scanning and a size of 37 mm, HEIDENHAIN is offering its portfolio of highly dynamic and energy-efficient servo drives for safety-related applications.
