KSM02.1B-071C-24N-M1-HP2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-M1-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding drive electronics directly on the motor, the unit provides decentralized motion control for conveyor segments, handling axes, and compact machine modules. In industrial automation, it simplifies cabinet wiring and shortens power and feedback cable runs while providing closed-loop positioning accuracy. The integrated arrangement also reduces the number of separate components that must be installed inside the control cabinet.

The drive is supplied by a DC 750 V intermediate circuit, so it connects to a shared DC bus instead of directly to the mains. Heat is removed through natural convection, eliminating the need for fans or liquid cooling lines. Power, control, and Ethernet signals share a single hybrid connector, which simplifies installation and reduces the risk of wiring errors. Position feedback is managed through a Hiperface encoder link, and the optical reader processes 128 signal periods per mechanical revolution for precise interpolated resolution. The encoder provides multi-turn absolute feedback, allowing the axis to report its position after a power cycle without completing a new homing sequence.

An electrically released brake clamps the rotor until the control line applies DC 24 V, preventing drift when the system is idle or powered down. Network traffic is handled by the integrated Multi-Ethernet interface, allowing the unit to join SERCOS, EtherCAT, or PROFINET networks. The frame has a size of 071 and motor length C, making it suitable for applications that require moderate torque within limited installation depth. Output torque is transmitted through a shaft with a keyway, while a shaft seal helps limit the entry of contaminants during routine operation. The unit has design version 1, a standard mechanical option, a basic performance level, and Series 2 construction. It uses winding code 24 and does not include integrated safety technology.
