Product Description:

The KSM02.1B-041C-42N-S1-HP0-ET-S3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and supplied within the KSM Motor Integrated Servo Drives series. By combining power electronics, control logic, and a servomotor in a single housing, the unit can be mounted close to the axis to reduce cabinet wiring in decentralized automation cells. This layout also shortens the distance between the drive and motor section, which helps keep the installation compact. It is intended for machinery that requires precise positioning and stable speed regulation during repetitive motion.

The drive operates from a bus voltage of DC 750 V. This bus level supports the power stage used in integrated servo applications. All power, feedback, and fieldbus conductors enter through a single Hybrid Connector, which simplifies installation and limits enclosure penetrations. Heat is removed by natural convection, so no external fan is required. Rotor position is reported over the Hiperface interface, and the optical encoder generates 128 signal periods per revolution. This feedback arrangement supports closed-loop control, while the encoder is single-turn and the unit is design version 1 and Series 2.

The motor section uses size code 041 with length code C, giving a compact footprint for space-constrained machinery. Its electromagnetic setup uses winding code 42 for balanced torque generation within the convection-cooled design. The mechanical layout follows the standard design option and uses a keyway shaft with an integral shaft seal. Control data are exchanged through the Multi-Ethernet interface, allowing connection to EtherNet/IP, PROFINET, or EtherCAT networks without additional option cards. Functional safety is provided by the Safe Motion package, the performance level is basic, and the unit does not include a holding brake.
