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

The KSM02.1B-076C-35N-M1-HG0-ET-NN-D7-TO-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. The design is Version 1 and belongs to Series 2, combining a brushless synchronous motor with an onboard inverter so axis control can be mounted directly on the machine frame. The device provides torque, position, and velocity regulation for decentralized stations where compact equipment and reduced wiring are required in industrial automation.

Power is supplied through a hybrid connector, which routes DC bus power, control signals, and feedback through a single sealed connection while accepting a nominal DC 750 V link voltage from the central supply. Heat generated by the electronics is removed through natural convection, so no external fan or liquid cooling loop is necessary. Control packets travel over a Multi-Ethernet interface, allowing the drive to operate as a slave on EtherNet/IP, PROFINET, or EtherCAT networks without additional option cards. Rotor position reaches the control loop through a Hiperface optical encoder that provides 128 signal periods per mechanical revolution, supporting accurate commutation and smooth motion at low speeds.

The feedback unit is a multi-turn absolute sensor, so the axis retains its position count through power cycles without requiring a homing routine. The motor has a frame size of 076 and a length code of C, providing a compact housing for installation near the driven mechanism. It uses winding code 35 for its electromagnetic configuration. A plain shaft transmits motion to the connected load without using a keyway. The shaft seal helps prevent contaminants from reaching the internal bearings and other rotating components. The drive is supplied without a holding brake, so an external mechanical device or drive-generated torque must retain static loads. The unit provides Basic performance for standard decentralized motion-control applications.
