KSM02.1B-071C-24N-M1-HG0-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines an electronic drive with a permanent-magnet motor in one housing, reducing the amount of wiring required inside the control cabinet. This integrated arrangement supports distributed motion axes in automated assembly stations, packaging lines, and material-handling cells.

The unit accepts a bus voltage of DC 750 V, providing the onboard inverter with sufficient energy for rapid acceleration and regeneration. Power, feedback, and network signals share a single hybrid connector, minimizing cable runs across the machine frame. Heat generated during operation is removed through natural convection, so no cooling fans are required. Position data are processed through a Hiperface interface, and the optical encoder supplies 128 signal periods per revolution. Its multi-turn absolute counting system retains shaft position after shutdown, eliminating the need for a homing cycle when power is restored. The drive has motor size 071, length code C, and winding code 24, which determines its electrical characteristics. It uses the standard design option and design version 1. The motor has no holding brake, so external mechanics or drive torque must secure the load when power is removed.

Fieldbus traffic runs over Multi-Ethernet, allowing software-based selection of SERCOS III, EtherNet/IP, PROFINET, or EtherCAT. The controller provides the Series 2 feature set and has a Basic performance tier. Integrated safety functions are not included, so STO and SS1 channels are unavailable. A shaft seal helps prevent lubricant migration and protects the bearing area from contaminants. Motion is transmitted through a plain shaft, which supports installation with an appropriate clamping coupling. The housing uses the standard finish without additional coatings.
