KSM02.1B-076C-35N-M3-HG0-ET-L3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-076C-35N-M3-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive from the Bosch Rexroth Indramat KSM Motor Integrated Servo Drives series. By combining a servo motor, power electronics, and a fieldbus interface in one housing, the unit simplifies wiring inside decentralized machine zones. It provides precise position, velocity, and torque control for packaging stations, pick-and-place modules, and other distributed axes within industrial automation systems.

Electrical power is delivered through a DC link rated at DC 750 V, giving the drive the overhead needed for rapid acceleration without requiring oversized conductors. A single hybrid connector carries both power and communication signals, so external junction boxes are unnecessary. Heat generated by the inverter is removed through natural convection, allowing installation in cabinets or open frames without forced airflow. Rotor feedback is transmitted through a Hiperface interface, and the built-in evaluator processes 16 signal periods per mechanical revolution to support precise closed-loop commutation at low speeds. The internal bus controller handles Multi-Ethernet communication and links the drive to EtherCAT, Sercos, or PROFINET masters without requiring hardware changes.

Motion accuracy is enhanced by the encoder's multi-turn absolute function, which allows the controller to recover the shaft position after a power loss without homing. Its capacitive sensing element maintains signal quality in the presence of magnetic stray fields. The integrated safety circuit supports Safe Torque Off (STO), removing gate-drive energy when a safety channel opens and eliminating motor torque within milliseconds. A plain shaft mates directly with zero-backlash couplings, and a shaft seal limits lubricant migration. The 076 frame size and motor length C are paired with the 35 winding code, providing a basic performance level suited to moderate-inertia loads. The drive is supplied without a holding brake, so vertical axes must be secured mechanically when power is unavailable.
