Product Description:
The KSM02.1B-041C-42N-M3-HG0-ET-L3-D7-TO-FW is an integrated servo drive manufactured by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. The device merges a synchronous motor, power stage, and fieldbus interface, allowing it to mount directly on moving machine parts while eliminating a centralized control cabinet. This layout places the inverter electronics close to the load, which supports machine designs with distributed motion axes. Intended for industrial automation, it provides decentralized axis control for packaging, handling, and assembly equipment where compactness, straightforward setup, and shorter cable runs are required.
The unit draws its intermediate circuit power from a DC 750 V supply and routes power, signals, and STO conductors through a single Hybrid Connector, which simplifies machine wiring and reduces cable entry points at the axis. Heat produced by the internal inverter is removed solely by natural convection, so no fan is required and the drive can be sealed against dust and spray. Position feedback travels through the Hiperface interface, and the encoder provides 16 signal periods per mechanical revolution, enabling stable speed regulation at low speeds. Multi-Ethernet output coupling and master communication allow real-time exchange over EtherNet/IP, PROFINET, or EtherCAT without additional gateway hardware.
Its sensing system relies on a Capacitive measuring principle that is immune to magnetic stray fields, and the encoder is Multi-turn absolute, so each power-up delivers an unambiguous shaft position without homing. Functional safety is integrated through Safe Torque Off, which disconnects the power devices so the motor cannot generate torque when the safety channel is asserted. The axis ships without a holding brake, making it better suited to horizontal or externally clamped mechanisms. It uses a plain shaft with a shaft seal, has motor size 041 and length C, and uses winding code 42. The unit also has a basic performance level and design version 1.
