Product Description:
The KSM02.1B-071C-35N-S3-HP2-ET-L3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining the servo motor, power electronics, and fieldbus interface in one housing, the unit supports decentralized motion axes that reduce control-cabinet space and wiring in automated handling cells, packaging lines, and material-flow systems. Because the inverter is mounted on the motor, the axis can be installed closer to the machine section it drives, which helps shorten motor leads and reduce cabinet-side hardware. Power, brake supply, and Ethernet share a single Hybrid Connector, which simplifies cable routing at the machine.
Rated for a supply of DC 750 V, the drive draws intermediate-circuit power directly from a centralized converter, which helps limit voltage drop across long DC networks. Heat is removed by natural convection, so the mounting orientation must allow vertical airflow and no serviceable fans are required. Position feedback is transmitted through a Hiperface interface, and the sensor delivers 16 signal periods per revolution for commutation. The underlying sensing principle is capacitive, so the feedback system does not rely on optical components that can be blocked by dust. The encoder is single-turn, giving an absolute value for one mechanical revolution, and the Multi-Ethernet interface can be assigned to PROFINET, EtherNet/IP, or EtherCAT. The motor has size 071, length C, and winding code 35, which match the basic performance level used in compact actuators.
The integrated brake is electrically released and clamps the shaft whenever enable signals are absent; it is powered by a DC 24 V supply delivered through the hybrid cable. Functional safety is implemented as Safe Torque Off (STO), which cuts motor energy internally to achieve PL e without external relays. A shaft seal is present, and the keyway shaft provides positive torque transfer to couplings while helping support enclosed machine installations.
