Product Description:
The KSM02.1B-076C-35N-S1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By placing power electronics directly on the motor, it reduces cabinet space and cable runs while delivering closed-loop motion control for decentralized axes in automated lines. This layout supports compact machine sections where remote mounting of separate drive hardware would add complexity. It is intended for rotary positioning tasks that require tight speed accuracy, and it is part of Series 2 of the platform.
This unit accepts a supply bus of DC 750 V, so it can be tied to a common DC link shared by multiple drives. Power, feedback, and brake conductors are bundled through a single Hybrid Connector, which simplifies wiring on modular machinery and keeps connections concentrated at one entry point. Thermal management relies on natural convection, so mounting must allow free airflow along the housing instead of depending on fan-assisted cooling. Position data comes from an optical encoder that communicates through a Hiperface interface. Its scanning resolution is organized into 128 signal periods, and the encoder is a single-turn device that reports absolute position within one mechanical revolution. This feedback arrangement supports stable servo regulation during speed and position control.
Command and diagnostic traffic are routed over the Multi-Ethernet master interface, allowing the same hardware to join EtherNet/IP, PROFINET, or EtherCAT networks without change. The drive uses the standard design option in design version 1, with a basic performance level, motor size 076, and motor length C. A shaft seal is installed, and the output end is a shaft with a keyway for positive torque transfer. The unit is supplied without a holding brake, so static load retention must come from the drive or external mechanics when power is removed. The electromagnetic section uses winding code 35, which matches the motor's electrical configuration.
