Product Description:

The KSM02.1B-071C-24N-S1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with integrated drive electronics, the unit mounts directly on the machine and closes the control loop at the axis. This arrangement reduces cabinet space and cable length in automated assembly lines, packaging systems, and material-handling stations. It functions as a decentralized axis that receives DC bus power and carries out precise position, velocity, and torque commands from the machine controller.

Power is supplied from a shared DC link at DC 750 V, so only two conductors need to run along the machine frame. All power, feedback, and safety lines terminate in a single Hybrid Connector, which keeps cable routing compact and orderly. Heat generated by the inverter is removed through natural convection, so no fans or liquid circuits are required. Control data are exchanged over a Multi-Ethernet interface that can be set to EtherNet/IP, PROFINET, or EtherCAT. Rotor position is captured by an optical Hiperface encoder that provides 128 signal periods per revolution, giving resolution suitable for pick-and-place and indexing applications.

Functional safety is provided by Safe Motion (with SBC), enabling stop and brake control without extra relays. Torque is transmitted through a shaft with a keyway, and a shaft seal helps block dust and splash. Size code 071 with length C keeps the actuator compact for basic performance applications, while winding code 24 matches the stator to the 750 V bus. The unit ships without a holding brake, so static loads require external clamping. Its single-turn encoder reports the absolute angle within one revolution, and the drive is built in standard version 1 with electronics in series 2.
