KSM02.1B-071C-24N-M1-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It combines a drive inverter, feedback electronics, and a 071-frame synchronous motor in one housing, allowing the axis to mount directly on machinery without a control-cabinet drive. This configuration streamlines installation in automated packaging lines, handling gantries, and other decentralized motion stations that require compact, self-contained servo control.

The drive operates from a nominal bus voltage of 750 VDC, allowing it to share a common DC network with other axes and regenerative supplies. Power, feedback, and I/O reach the unit through a single hybrid connector, which reduces the cable count and simplifies daisy-chain layouts. Heat generated by the embedded inverter is removed through natural convection; no forced-air fans are required, so enclosure depth stays minimal and maintenance requirements are reduced. Rotor position data are transmitted over a Hiperface serial link, combining absolute data with incremental tracks for high-speed control loops. The optical encoder provides 128 signal periods per mechanical revolution, supplying the controller with detailed angle information for smooth velocity regulation.

Network traffic is handled by the built-in Multi-Ethernet interface, which supports common industrial Ethernet protocols without additional option cards. Absolute angle retention across power cycles is provided by a multi-turn absolute measuring system, eliminating the need for homing routines at startup. Shaft holding torque is generated by an electrically released brake that engages whenever the enable signal is lost, and its coil is energized by a dedicated 24 VDC supply through the hybrid lead. The motor has a plain shaft with an internal shaft seal and uses winding code 24. The unit has a basic performance classification and is supplied as a standard design in Version 1.
