Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-SD-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. Version 1 of this second-generation design places power electronics, safety circuits, and a synchronous motor in one housing that mounts directly on the machine frame. The device delivers decentralized axis control for packaging, material-handling, and assembly cells, reducing cabinet wiring while keeping diagnostic data close to the actuator. By combining the inverter and motor in one unit, it supports compact machine layouts where separate drive modules would add cable length and enclosure space.

It is supplied from a DC 750 V bus and dissipates heat to the surrounding air through natural convection, so no external fan is required. Power, communication, and brake conductors reach the drive through a single hybrid connector, which combines these connections in one interface and helps keep routing simple near the axis. Position feedback is furnished by an optical Hiperface encoder that provides 128 signal periods per revolution in a single-turn layout, giving the controller absolute position after each power cycle. Safe Motion with SBC is available, and motion commands are exchanged through the integrated Ethernet interface for coordinated operation with the control system.

The motor uses size 041 with body length C. Winding code 42 matches the electrical characteristics of the motor to the drive. A plain shaft runs through a radial shaft seal, which helps limit splash ingress even though the drive is shipped without a holding brake. The unit also supports Multi-Ethernet output coupling for daisy-chain network wiring, which helps extend communication to the next device without separate branching hardware. This arrangement suits compact machine sections where multiple decentralized axes share the same network path along the frame.
