Product Description:
The KSM02.1B-041C-42N-S1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It consolidates inverter electronics, feedback, and the power stage directly on the motor, enabling decentralized axis control without a separate cabinet drive. The device belongs to Series 2 and uses a basic performance level, making it suitable for general motion tasks such as indexing tables, carton erectors, and assembly heads where compact installation and moderate torque density are useful. By placing the drive at the motor, the design shortens internal connections and helps simplify cable routing on moving machine sections with limited installation space.
Electrical energy is supplied through a DC 750 V bus that allows multiple axes to share braking and regeneration power. A single Hybrid Connector carries the DC link, logic supply, and fieldbus signals, reducing cable runs on linear tracks and rotary modules. Heat from the power electronics is removed by natural convection, so no fans or external coolant are required and enclosure planning stays simple. Rotor position is measured with a Hiperface optical encoder that generates 128 signal periods per revolution, giving the controller fine incremental data for smooth velocity and position loops.
The feedback device stores absolute angle as a single-turn value, which supports restart behavior on short-stroke mechanisms without requiring a full revolution count. Communication with higher-level PLCs is handled through Multi-Ethernet, so the same drive platform can be used with EtherNet/IP, Sercos III, PROFINET, or EtherCAT networks. The output is transmitted through a plain shaft with a shaft seal, and its electromagnetic characteristics follow winding code 42 for motor size 041 and length C. The standard design option and design version 1 are retained, and the unit comes without a holding brake or integrated safety functions. This arrangement suits compact machine sections where the drive hardware must travel with the axis and available installation space is limited.
