Product Description:

The KSM02.1B-076C-35N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive engineered by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining a brushless servo motor, power electronics, and fieldbus interface into one housing, the unit controls rotary positioning tasks directly on the machine frame and simplifies cabinet wiring for distributed automation. Axis commands are exchanged through the controller-agnostic Multi-Ethernet interface, which supports several real-time protocols without hardware changes. This arrangement is well suited to decentralized motion systems where compact installation and short cable runs are important.

It accepts a supply of DC 750 V, so the drive section can be powered from a shared DC bus without an additional converter. Power, signal, and safety lines enter through a single Hybrid Connector, which reduces cable count while keeping connections grouped at one entry point. Heat generated by the integrated inverter is removed by natural convection, so no external fan or liquid circuit is required. Position feedback travels over the Hiperface bidirectional link, allowing absolute position transfer and automatic parameter download. Within the encoder, 128 signal periods per revolution provide suitable resolution for indexing, labeling, and small-angle interpolation.

The encoder uses an optical scanning principle, which provides high immunity to magnetic stray fields, and it delivers one mechanical turn of data because the system is single-turn. The output shaft is a plain shaft, allowing direct coupling to gears or pulleys without key seats, and a shaft seal is fitted to protect the internal bearings against coolant spray. Functional safety is delivered by the integrated Safe Motion circuitry, which can execute safe torque off and safe stop functions without an optional safety brake. The 076 frame size, C length, and winding code 35 set the continuous torque, speed range, and thermal mass for medium-power packaging or handling robots.
