The KSM02.1B-041C-42N-M1-HP0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It merges a permanent-magnet servomotor, power stage, and network interface in a sealed body so that motion control functions can be mounted directly on the machine frame. The product generates controlled torque and position feedback for industrial axes and helps simplify cabling in decentralized automation layouts.
The drive draws its direct-current bus from a supply voltage of DC 750 V, a level that matches the common DC link provided by Rexroth supply modules and allows long motor cables without excessive losses. Thermal energy is removed by natural convection; no fans are installed, so orientation and free airflow around the aluminum housing are critical for continuous rating. Power, feedback, and brake lines are consolidated in a single Hybrid Connector, which simplifies replacement and minimizes connector count on the machine. Rotor position is measured by an optical encoder that communicates over the Hiperface interface, and its interpolation is based on 128 signal periods, giving the controller fine angular resolution for smooth velocity loops.
Motion commands reach the unit through the fieldbus stack designated as Multi-Ethernet, enabling selection among Sercos III, EtherNet/IP, EtherCAT, or PROFINET without hardware changes. Mechanically, the output shaft is machined as a shaft with keyway, allowing positive-fit coupling to gears or pulleys and supporting the installed shaft seal that protects the internal bearings from splash ingress. The motor portion follows size code 041 with length code C and winding code 42, yielding torque and speed values suited to mid-range handling tasks. As a drive classified at the Basic performance level, it omits integrated safety technology and incorporates design version 1 in the standard option package.
