Product Description:

The KSM02.1B-041C-42N-S1-HG2-ET-S3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. Classified as Series 2 with a Basic performance level, the unit combines a size 041 stator with a C-length frame to place power electronics, feedback, and motion control in the same compact enclosure. This arrangement eliminates separate panel drives and shortens motor cables, supporting decentralized installation on conveyors, pick-and-place axes, and material-handling stations that require precise torque and velocity regulation.

The drive accepts a DC 750 V supply fed through a single Hybrid Connector, so DC power, safety I/O, and network lines reach the motor over one cable. Heat is removed by natural convection, eliminating the need for fans and allowing installation in sealed machine spaces. For networked control, the built-in Multi-Ethernet interface supports PROFINET, EtherNet/IP, and EtherCAT. Motion feedback is handled through the Hiperface encoder interface, and winding code 42 identifies the electromagnetic package used to deliver rated torque under this voltage. The hardware corresponds to design version 1.

The servo uses an electrically released brake that engages automatically when the control signal drops, and a dedicated DC 24 V line keeps it open during normal operation so vertical or indexing axes can stop safely on power loss. Position data comes from an optical encoder that generates 128 signal periods per revolution, providing fine resolution for Safe Motion functions without an additional safety bus. The underlying sensor technology is optical, and the single-turn format suits applications that return to a home reference at power-up. A plain shaft with a factory-installed shaft seal protects the bearings, while Safe Motion functions without SBC run directly on the drive to reduce external wiring.
