Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-L3-D7-AN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servo motor with an embedded drive controller, it provides decentralized motion control for axis groups in packaging, handling, and assembly lines. Its size 041 stator and length code C create a compact envelope that mounts directly on machinery. The basic performance level suits moderate load profiles and routine positioning tasks. Because the inverter is built into the motor housing, the axis can be distributed across the machine frame without relying on a separate drive cabinet at each station.

Operating from a bus of DC 750 V, the unit receives power and fieldbus lines through a Hybrid Connector, which reduces separate cabling. This connection approach helps keep installation routes compact on transfer modules and other space-limited assemblies. Heat from the embedded electronics leaves the housing through natural convection, so neither fans nor liquid loops are needed when ambient air can pass the fins. Motion commands reach the drive through the Multi-Ethernet master interface, which supports PROFINET, EtherNet/IP, or EtherCAT. Rotor position is sensed by a Hiperface optical encoder that outputs 128 signal periods per revolution, giving the controller fine electrical angle data for commutation and closed-loop control. The unit uses design version 1, winding code 42, and a series 2 board set.

The feedback system uses a single-turn absolute scale, which stores rotor position within one mechanical revolution. The integrated Safe Torque Off (STO) channel disables the power transistors while leaving communication active when the safety chain is opened. Output torque is transferred by a plain shaft equipped with a shaft seal that helps keep grease inside and dirt out. This sealed shaft arrangement supports installations where contamination control around the bearing area is important. The ATEX version housing permits installation in areas where conductive dust or gas may be present. This model is supplied without a holding brake, so vertical loads must be secured by external holding devices.
