Product Description:
The KSM02.1B-071C-35N-M1-HP0-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining power electronics, feedback, and a synchronous servo motor in one housing, the unit streamlines mounting in distributed automation cells. It is intended to position or regulate motion axes in packaging machines, material-handling gantries, and other equipment that benefits from decentralized drive placement to shorten cable runs and reduce panel heat.
The drive operates from a bus supply of DC 750 V, and heat generated by the power stage is removed through natural convection, allowing cabinet-free installation where ambient airflow is available. A sealed Hybrid Connector carries power, safety I/O, and feedback on a single cable, while the master axis controller transfers real-time commands over Multi-Ethernet so that PROFINET, EtherNet/IP, or EtherCAT networks can be selected in software. Rotor position is captured by a Hiperface optical encoder that delivers 128 signal periods per revolution and stores absolute multi-turn data, allowing position information to remain available after power loss. Motor size 071, length C, and winding code 35 determine the electrical and mechanical combination used in this unit, and the standard design with hardware version 1 supports mid-range handling tasks.
The output shaft has a keyway and is supplied without a holding brake, so any static load must be secured by external mechanics or drive torque. A shaft seal is fitted at the nose to help limit lubricant escape and the entry of fine particles. The unit supports Safe Motion, although the configuration does not include an SBC relay. It is part of series 2 with variant S3 and uses the Basic performance class for deterministic motion control.
