Product Description:

The KSM02.1B-071C-35N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and supplied as part of the KSM Motor Integrated Servo Drives series. Belonging to series 2 of this decentralized product family, it combines a brushless servo motor and drive electronics inside a single housing, allowing placement directly on the machine frame. In automated assembly stations or conveyor systems, the drive provides precise closed-loop motion while reducing cabinet wiring and supporting modular machine layouts used in industrial automation where compact decentralized axis control is preferred.

The drive accepts a bus voltage of DC 750 V that is carried, along with logic power and safety lines, through a single hybrid connector. Heat is removed by natural convection, so no auxiliary fan is required. Position feedback uses a Hiperface interface, and its optical encoder generates 128 signal periods per revolution in a single-turn format, allowing absolute position recovery at power-up. Network integration is handled by the Multi-Ethernet master port, giving the choice of Sercos III, PROFINET, EtherNet/IP, or EtherCAT from the same hardware. The motor uses a 071 stator size, length code C, and winding code 35, while the plain shaft transmits torque directly and the integral shaft seal helps prevent lubricant escape.

The unit is supplied in the standard mechanical configuration and is identified as design version 1. Its control feature set is classified as Basic, and integrated Safe Motion functions permit speed and position monitoring without an additional safety bus coupler. Because the motor comes without a holding brake, static load retention must be handled by external mechanics or drive torque. This arrangement places power conversion and feedback handling directly at the axis, which helps keep decentralized machine layouts compact.
