KSM02.1B-076C-35N-S1-HG2-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S1-HG2-ET-S3-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series from Bosch Rexroth Indramat. As a motor-integrated servo drive, it combines the power stage, control electronics, and servomotor in one housing to reduce cabinet space and wiring. In automated assembly lines, packaging machines, or material-handling axes, this design supplies torque and closed-loop positioning directly at the mechanical load while communicating with higher-level motion controllers through real-time industrial networks.

The drive operates from a bus voltage of DC 750 V, providing inverter headroom for rapid acceleration without requiring step-down transformers. Network traffic is handled through Multi-Ethernet, so the same hardware can join EtherNet/IP, PROFINET, EtherCAT, or SERCOS III networks through a parameter change. Rotor position is captured through a Hiperface feedback channel; this digital interface combines power and data over two conductors, allowing automatic setup and electronic nameplate transfer. The optical encoder provides 128 signal periods per mechanical revolution, supplying adequate resolution for standard motion profiles while keeping the processing load moderate. Thermal energy leaves the housing through natural convection, so no fan is required; the mounting orientation must permit vertical airflow to maintain the rated current.

The holding mechanism is energized by DC 24 V; when power is removed, spring force quickly engages the brake to secure vertical or suspended loads. Torque reaches the output through a plain shaft, eliminating key-induced eccentricity and supporting the use of clamp or shrink couplings. A single hybrid connector carries the DC bus, control voltage, network lines, and brake conductors, which shortens installation time and limits potential wiring errors. Integrated diagnostics support Safe Motion without SBC, enabling certified functions such as Safe Stop 1 or Safe Limited Speed without external relays. A factory-installed shaft seal protects the shaft opening, while the C-length magnetic stack and winding code 35 support basic-performance duty cycles.
