KSM02.1B-076C-35N-S3-HP0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-S3-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor with an onboard inverter, it delivers decentralized motion control without a separate cabinet-mounted drive. In automated production lines, the unit mounts close to the load, reducing cable runs and simplifying installation.

The drive accepts a supply of DC 750 V, which is the intermediate-circuit voltage distributed from a central power supply. Power, control, and safety signals are routed through a single hybrid connector, minimizing wiring time. Heat generated by the inverter is removed through natural convection, so no forced-air fans are required. Position feedback is provided through a Hiperface interface, and the encoder generates 16 signal periods per mechanical revolution, giving adequate resolution for indexing and general handling tasks. The sensing element uses capacitive technology to withstand vibration and temperature swings, and it operates as a single-turn device that reports absolute position within one revolution.

On the control side, real-time commands are exchanged over Multi-Ethernet, allowing integration with EtherNet/IP, PROFINET, or EtherCAT networks. The embedded safety circuit supports Safe Torque Off (STO), allowing machines to meet Category 3 PL d requirements without separate contactors. The motor has a frame size of 076 and length code C, a combination that balances torque and overall size for packaging or assembly axes. A shaft with a keyway provides positive mechanical coupling, and a shaft seal is fitted to limit ingress. The unit is supplied without a holding brake, so static load retention must be handled externally. The product has a Basic performance level, while winding code 35 sets the electrical constants. It follows design version 1 in the standard execution of Series 2.
