KSM02.1B-071C-24N-S1-HP0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-S1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. As a compact axis that combines a servo motor with drive electronics, it reduces cabinet space and simplifies wiring in distributed automation. This unit belongs to series 2, has motor size 071 with length C, and uses winding code 24 to support mid-range torque demands on packaging, material-handling, and assembly lines.

The drive accepts a bus supply of DC 750 V. Rectified intermediate voltage is routed internally to the inverter stage, so no separate low-voltage source is needed. Power, signal, and safety lines are combined in a single hybrid connector, streamlining installation and daisy-chain layouts. Heat is removed through natural convection, eliminating the need for fans in washdown or quiet areas. Rotor position is sampled by a Hiperface encoder that delivers 128 signal periods per mechanical revolution. The optical scanning head produces high signal-to-noise feedback for accurate speed loops. The encoder electronics are mounted in the motor housing, shortening analog paths and improving noise immunity.

The position sensor tracks one mechanical turn using a single-turn configuration suited for axes that return to a home position at power-up. Functional safety is embedded through Safe Motion with SBC, allowing certified STO and safe-stop routines without external relays. Command traffic moves over Multi-Ethernet, so the same hardware accepts EtherNet/IP, PROFINET, or EtherCAT depending on the network settings. The hardened shaft interface uses a shaft with a keyway to secure pulleys or gearheads, and a shaft seal keeps lubrication inside the housing. The drive uses the standard design option, version 1, and the basic performance level. It is supplied without a holding brake, so static loads must be secured by external means.
