Motor Technology has introduced a range of single and three phase servo positioning controllers, described as 'truly universal' because they can be connected to a wide range of encoder systems and motor types. The Metronix ARS servo drives can be connected to resolvers, incremental encoders, absolute encoders with EnDat or HiperFace interfaces, high-resolution Stegmann incremental encoders, and incremental encoders with or without communication signals. The new drives will also control different motor types such as torque motors, linear motors or synchronous motors. Two technology slots on the front panel of the drives enable users to plug in various fieldbus networking modules such as Profibus, Sercos and Ethernet as well as I/O expansion and service modules.
