KSM02.1B-076C-35N-M1-HP2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M1-HP2-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 a permanent-magnet motor, power electronics, and local I/O in a single housing, the unit simplifies distributed motion architectures and reduces cabinet wiring. It is intended for machines that need compact axis modules, such as packaging stations, small handling robots, or material-flow conveyors where decentralization shortens feedback loops.

The drive connects through a single hybrid connector that carries power, Ethernet, and safety lines, so installation requires only one preassembled cable. Heat generated by the inverter section is dissipated through natural convection; no fans are mounted, which eliminates particulate airflow and reduces maintenance requirements. Motion feedback is provided by a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution and stores absolute multi-turn position data in onboard memory. Network access uses Multi-Ethernet communication, allowing selection among EtherNet/IP, PROFINET, and EtherCAT without hardware changes. The power stage accepts a bus voltage of DC 750 V, matching the common intermediate circuit found in modular converter systems. The motor has a size of 076, a length code of C, and a winding code of 35, providing a torque-speed profile suitable for the platform's basic performance level.

An electrically released holding brake secures the rotor when control power is removed. It engages automatically when the supplied DC 24 V brake line is de-energized. Integrated safety provides Safe Motion without SBC, permitting STO, SLS, and other motion-based functions through the real-time fieldbus. Mechanical power flows through a shaft with a keyway, and a shaft seal is fitted to limit lubricant leakage and dust entry. The drive has the standard design option, design version 1, and series identifier 2.
