Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics with a permanent-magnet motor, the unit streamlines installation on modular machines and eliminates long feedback cables. This arrangement places power conversion close to the axis, which helps reduce cabinet-side wiring and supports compact machine layouts. It provides decentralized axis control for material handling, packaging, and assembly stations that rely on precise positioning.

Its power stage is fed from a DC 750 V shared bus, allowing direct coupling to regenerative supply modules in multi-axis systems. This arrangement also lets connected axes exchange energy through a common DC link during acceleration and deceleration. Field wiring is simplified by a single Hybrid Connector that carries power, signals, and safety lines. Heat generated by the onboard inverter is removed through natural convection, so no fans are required and enclosure integrity is maintained. Position feedback is generated by an optical encoder that outputs 128 signal periods per revolution through the Hiperface interface, providing absolute single-turn data to the controller immediately after power-up. The motor uses winding code 42 with a C-length housing and does not include an integrated holding brake.

Command and diagnostics travel over Multi-Ethernet, enabling real-time communication through Sercos, EtherNet/IP, PROFINET, or EtherCAT without extra hardware. This allows the drive to fit different network environments while keeping the same integrated axis concept. Functional safety is embedded as Safe Motion (without SBC), providing certified stop and speed monitoring when the appropriate STO lines are activated. The motor has frame size 041 and a plain shaft with a shaft seal, and the housing is series 2 with design version 1. This shaft arrangement helps protect internal components in light washdown areas while maintaining a compact mechanical package.
