Product Description:

The KSM02.1B-071C-35N-S1-HG2-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat and positioned within the KSM Motor Integrated Servo Drives series. It is series 2 and design version 1, with a standard design option for direct machine mounting on decentralized machine sections. By combining the motor, power electronics, and communication interfaces in one housing, it reduces the number of separate components needed at the axis and supports compact machine layouts. This layout is suited to packaging equipment, transfer modules, and other machines where the drive must be mounted close to moving assemblies.

Electrical energy is provided by a DC 750 V intermediate circuit, and heat is removed solely by natural convection, so the housing operates without forced airflow. Power, feedback, and Ethernet conductors share a Hybrid Connector, which helps keep external wiring compact in tight spaces. Position data reach the drive through a Hiperface optical encoder that delivers 128 signal periods per revolution while maintaining single-turn tracking. A plain shaft with a shaft seal transfers torque, and an electrically released holding brake engages when control voltage is absent. The motor section uses winding code 35 and length code C, which match the physical format of this integrated axis unit.

System coordination occurs over Multi-Ethernet, enabling communication with SERCOS III, EtherNet/IP, PROFINET, or EtherCAT controllers. This protocol flexibility lets the same integrated drive package work with different control platforms. Functional safety is provided by Safe Motion with SBC, allowing safe torque-off and safe stop functions without external relays. The mechanical envelope corresponds to Motor Size 071, giving a balance between inertia and continuous torque for mid-range axes, and brake holding power is supplied at DC 24 V.
