Product Description:
The KSM02.1B-071C-35N-M3-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines a brushless servo motor, power electronics, and a fieldbus interface in one enclosure, allowing installation close to the machine axis and reducing control cabinet wiring. In distributed automation lines, this layout provides position, speed, and torque control at the point of use, which supports coordinated motion on packaging, handling, and transfer equipment without a separate drive rack. Because the inverter electronics are mounted with the motor, cable runs between the drive and axis stay short and installation remains compact.
The unit is powered from a DC 750 V shared bus and receives all power, logic, and network conductors through a single Hybrid Connector. Heat generated by the power stage is removed by natural convection, so no forced-air or liquid cooling hardware is required around the housing. Communication with PLCs is handled by Multi-Ethernet, which allows EtherNet/IP, PROFINET, or EtherCAT selection through software. Rotor position is sampled by the feedback system, and the disk inside the feedback head yields 16 signal periods per revolution to support fine interpolated positioning. This arrangement also reduces the number of separate cable entries at the machine frame.
The motor section uses frame size 071 and length code C, giving a compact footprint while accommodating winding code 35 for its rated torque range. Position data come from a Hiperface transducer that relies on capacitive sensing and stores multi-turn absolute values without battery support. Output torque is transmitted through a shaft with a keyway, and a shaft seal is installed to limit ingress around the drive end. The device is supplied without a holding brake, follows design option Standard and design version 1, carries series index 2, and does not include integrated safety circuits, so external safety hardware is required when that function is needed.
