KSM02.1B-071C-24N-M1-HP0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-M1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. As a Series 2, Design 1 standard model, it embeds drive electronics directly on a synchronous motor so the axis can be mounted outside the control cabinet. This arrangement reduces the amount of equipment required inside the cabinet while keeping motor control close to the driven axis. The compact, decentralized design is suitable for positioning and velocity tasks in automated assembly stations, conveyor modules, and material-handling systems.

The drive accepts a bus supply of DC 750 V, which energizes the inverter stage that operates with winding code 24. Power, encoder, and safety signals are routed through a single hybrid connector, simplifying daisy-chain installations along the machine frame. Heat generated by the integrated electronics is removed through natural convection, eliminating the need for fans and supporting the use of a sealed enclosure. Axis commands and diagnostic traffic are exchanged through Multi-Ethernet, enabling real-time operation on SERCOS III, EtherNet/IP, or PROFINET networks without changes to the communication hardware. Position feedback provides 128 signal periods per motor revolution, supporting accurate angular measurement for electronic gearing and camming functions.

An optical scanning method within the Hiperface feedback system supplies absolute position data. Its multi-turn track counts complete revolutions, so the axis retains position information across power cycles without requiring a new homing routine. Integrated Safe Motion with SBC functions meet Category 3 requirements and allow the controller to monitor velocity and stopped states. The product has a Basic performance level. The motor has a length code of C and a frame size of 071, providing a suitable torque class for medium material-handling axes. Mechanical energy is transmitted through a shaft with a keyway. The assembly is supplied without a holding brake, so an external mechanism must secure vertical loads when power is removed.
