KSM01.2B-076C-35N-M1-HG0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-076C-35N-M1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive developed by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding the power stage and feedback processing inside the motor housing, the unit supports decentralized axis control on production lines and material-handling equipment. The integrated arrangement reduces the need for separate drive cabinets while permitting closed-loop control from a central motion platform. The product belongs to Series 1 and combines the motor, inverter electronics, and position feedback components in one housing.

Power, signal, and brake conductors share a single hybrid connector, reducing the number of connections required at the junction box. The electronics are supplied from a 750 VDC bus, allowing the axis to connect to high-voltage, multidrive DC-link networks. Heat is removed through natural convection, so the drive does not require fans or liquid cooling circuits when installed with sufficient open airflow. Real-time command data is exchanged over SERCOS 2 (RS-422), allowing deterministic synchronization with an upstream motion controller. Position feedback is processed through the Hiperface interface for closed-loop position and speed regulation. The unit has design version 2, a standard design option, winding code 35, motor length C, and frame size 076.

The sensing system uses an optical encoder that generates 128 signal periods per mechanical revolution. Position data are stored as a multi-turn absolute value, allowing the controller to retain the axis position across multiple shaft revolutions after power is removed. Torque is transmitted through a plain shaft, and an installed shaft seal helps limit the entry of dust and fluids around the output interface. The unit is supplied without a holding brake, so an external mechanism or another suitable method must secure the load when drive torque is unavailable. Its basic performance level supports standard motion-control functions, while the configuration does not include additional integrated safety technology. This arrangement is appropriate for machines in which safety functions and stationary load retention are handled elsewhere in the control system.
