KSM02.1B-071C-24N-S1-HG0-ET-S3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive from the Bosch Rexroth Indramat KSM Motor Integrated Servo Drives series. By combining the motor, power electronics, and network interface in one housing, it streamlines axis installation in packaging, assembly, and material-handling machines. The unit delivers closed-loop torque and position control directly at the drive end, reducing cabinet wiring and supporting decentralized automation layouts.

Power and field wiring enter through a hybrid connector that carries DC bus, control, and feedback lines in one plug, shortening installation time and minimizing the connector count. The internal inverter is energized from a 750 V DC intermediate circuit, which supports lower motor currents and smaller conductors. Heat produced by the switching devices is dissipated through the aluminum frame by natural convection, so no additional fans or liquid cooling loops are required for continuous duty. Command and diagnostic traffic uses a Multi-Ethernet interface that can be configured for Sercos III, EtherNet/IP, EtherCAT, or PROFINET without hardware changes. Rotor position signals are transmitted through a Hiperface encoder interface for use by the drive's closed-loop control system.

The encoder uses an optical scanning head to read a coded disk and generate 128 signal periods per mechanical revolution, providing fine interpolation for smooth velocity control. Functional safety is handled by the integrated Safe Motion package without SBC, which provides supported motion-safety functions without safe brake control. Mechanical power is transmitted through a plain shaft with a shaft seal, helping prevent oil mist and dust from reaching the bearings. The motor has size 071, length code C, and winding code 24 to match the integrated drive electronics. It is produced in design version 1 with the standard option set and a basic performance rating. The unit is supplied without a holding brake and uses single-turn absolute feedback.
