Product Description:

The KSM02.1B-041C-42N-S1-HP0-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, feedback electronics, and a power stage in a single housing, it simplifies distributed motion axes on modular production lines. It belongs to series 2 of the KSM platform and is mounted directly on the machine frame to reduce cabinet heat load while executing basic motion tasks in industrial automation. This format suits modular conveyors, transfer units, and handling stations where each axis needs local drive power and short motor leads.

The drive uses a Hybrid Connector so power, safety circuits, and fieldbus lines share one cable, minimizing moving cable weight on decentralized axes. Heat is removed by natural convection, so no fan is required and surrounding clearance becomes important for stable operation. Position data travels over a Hiperface link that ties the optical encoder to the controller. The power stage accepts DC 750 V from a common DC bus. A shaft with a keyway provides positive torque transfer to couplings, pulleys, or gear inputs. The unit has motor size 041, length code C, winding code 42, a basic performance level, design version 1, a shaft seal, and no holding brake.

The integrated network interface uses Multi-Ethernet, enabling PROFINET, EtherNet/IP, or EtherCAT selection without hardware changes and matching the master communication setting. Each revolution is subdivided into 128 signal periods by the encoder and evaluated within a single-turn range, which supports repeatable position capture over one mechanical turn. Functional safety is delivered through Safe Torque Off (STO), which interrupts drive power through the hybrid plug instead of external relays. This arrangement supports compact decentralized axes that need integrated communication, feedback, and safety functions at the motor location.
