KSM02.1B-061C-35N-S1-HG0-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-S1-HG0-ET-S3-D7-TO-FW is an integrated servo drive module produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining power electronics with a synchronous motor in a single housing, the unit mounts directly on machinery and delivers decentralized motion control for industrial automation lines. The drive is design version 1 and belongs to Series 2 of the platform. Its 061 frame, C length, and winding code 35 establish the motor configuration and electromagnetic characteristics.

Its power stage is rated for DC 750 V, allowing the drive to share a common DC bus with other converters while keeping motor cabling short. Command data reach the unit over the Multi-Ethernet network connection, which supports integration with EtherNet/IP, PROFINET, or EtherCAT control systems. Rotor position is captured through a Hiperface interface that supplies absolute feedback to the motion controller. The optical encoder provides 128 signal periods per mechanical revolution, supporting consistent velocity and position control. Internal heat is dissipated by natural convection, removing the need for forced-air channels in confined mounting locations and reducing the number of auxiliary cooling components required around the drive.

Power, signal, and safety wiring pass through a single hybrid connector, simplifying cable routing between the drive and the rest of the machine. The output end uses a plain shaft with a shaft seal, which limits fluid ingress while allowing a compatible coupling to slide onto the shaft without a keyway. The drive is supplied without a holding brake, so vertical axes and static loads require an external locking device when motor torque is unavailable. The embedded Safe Motion package without SBC reaches Performance Level e and supports monitored stop and limited-speed functions within the drive. Because Safe Brake Control is not included, any external brake used by the application must be operated through suitable separate control equipment.
