Product Description:
The KSM02.1B-071C-35N-M1-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By merging a synchronous motor with onboard power electronics, it eliminates a separate cabinet-mounted drive and shortens cable runs in automated systems. The unit is design version 1 with the standard mechanical option, fits the 071 frame in length class C, and belongs to the basic performance level for decentralized axes that need accurate positioning and simple setup.
Its power stage operates from a common DC bus at DC 750 V, supporting multi-axis installations that share energy. Motor, feedback, and service lines are combined in a single Hybrid Connector, reducing panel components and simplifying wiring. Heat generated by the electronics is removed by natural convection; no fans are fitted, so mounting must allow unobstructed airflow. Position feedback is supplied by an optical encoder that communicates through the Hiperface protocol and delivers 128 signal periods per revolution, providing adequate granularity for precise velocity and position loops. The encoder stores multi-turn absolute data, so homing cycles are unnecessary after power interruptions.
Control traffic to the machine network runs through the Multi-Ethernet interface, allowing protocol selection such as EtherNet/IP, PROFINET, or EtherCAT through parameter settings. To meet functional safety requirements, the integrated Safe Torque Off (STO) circuit removes drive energy on demand while keeping the encoder powered. A plain shaft with a shaft seal helps block lubricant escape and maintain enclosure integrity at the output end. The electromagnetic package corresponds to winding code 35, and the unit is supplied without a holding brake, which suits applications that must coast freely after shutdown. The product is in Series 2.
