Product Description:
The KSM02.1B-071C-35N-M3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. By combining the drive electronics and motor in one housing, the unit removes the need for a separate panel-mounted inverter and long motor cables, which helps keep distributed machine sections compact. This layout also shortens the distance between the power stage and the motor windings. It is intended for coordinated axis motion in packaging, handling, and assembly lines where decentralized drives reduce wiring complexity and keep connections close to the moving axis.
The power section runs on DC 750 V, supplied through a Hybrid Connector that carries DC, signal, and brake conductors in one plug. This arrangement keeps the electrical connections grouped at one entry point and reduces the amount of separate cabling around the axis. Heat is removed by natural convection, so installation must allow unobstructed airflow without fans. Control data travel on Multi-Ethernet, enabling real-time motion over EtherNet/IP, PROFINET, or EtherCAT, and the integrated circuit provides Safe Torque Off (STO) for safety-related shutdown. This model uses the standard design option in design version 1, is Series 2, and has a basic performance level. The motor uses winding code 35 in a 071 frame with length C, and a shaft seal is fitted at the output to help block oil or dust.
Rotor position is measured through a Hiperface interface that reads a capacitive sensor system with 16 signal periods, while multi-turn absolute tracking records revolutions during power loss. This allows the controller to retain position information after interruptions without depending only on relative counts. The electrically released brake receives DC 24 V to clamp the shaft when motion is disabled, which helps prevent drift on vertical axes. Because the brake is spring applied, holding force remains available during a fault condition. A keyed shaft transmits torque to couplings, and encoder data reach the controller through the same combined cable to reduce external wiring.
