KSM02.1B-076C-35N-M1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

Bosch Rexroth Indramat's KSM02.1B-076C-35N-M1-HG0-ET-S3-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series and combines a permanent-magnet servo motor with embedded power electronics. By integrating drive, feedback, and network interfaces into a single housing, the unit enables decentralized axis control in conveyors, packaging machines, and material-handling stations. Instead of routing motor cables back to a central cabinet, the drive mounts directly on the machine frame and receives power from a common DC link, simplifying wiring and reducing electromagnetic emissions in industrial automation layouts.

The drive operates from a bus voltage of DC 750 V, allowing long power daisy chains in multi-axis lines without additional transformers. A single hybrid connector carries the DC supply together with communication and brake leads, decreasing the number of required connections. Heat is removed through natural convection, so no fans are required and cooling does not depend on forced airflow. Position and speed feedback is transmitted through Hiperface signals generated by the integrated optical encoder. Motion commands reach the unit through the Multi-Ethernet interface, which supports communication protocols such as EtherNet/IP, PROFINET, and EtherCAT.

The optical encoder supplies 128 signal periods per revolution and uses a multi-turn absolute system, so the drive can report the shaft position across power cycles without requiring a homing routine. Functional safety is handled by the Safe Motion package, which monitors speed and position internally even though Safe Brake Control is not installed. Torque is transmitted through a plain shaft with a shaft seal, helping protect the motor interior from contaminants. The motor has size 076, length C, and winding code 35 for the basic performance class. It is internally classified as Series 2 and is supplied as design version 1. The assembly has a standard mechanical option set and comes without a holding brake, so external load retention may be necessary when the axis is stationary and drive power is unavailable.
