The R911279831 (HDS04.1-W200N-HS11-01-FW) is an Indramat Rexroth DIAX04 HDS drive controller designed for 200A current. Known for its exceptional modularity, this controller uses SERCOS interfaces for external communications and control systems. It's also equipped with a plug-in module that facilitates analog interface control. This versatile drive controller is compatible with an array of rotary and linear motors including LSF, ADF, MHD, LAR, MBW etc. The R911279831 (HDS04.1-W200N-HS11-01-FW) has four operational modes - position, velocity, torque, and drive-interpolated. This drives the attached load to a certain position via cascade controlling. Operating at an input voltage range of 530-670 VDC, this controller can continually supply a current of 120 amperes at 500 VAC. Important information and error codes are displayed on a 7-segment display in front. Enhanced with in-built safety watchdogs, this model comes with a one-year global shipping warranty from Indramat USA.
