Product Description:

The KSM02.1B-041C-42N-M1-HG0-ET-L3-D7-AN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining drive electronics and a servo motor in one housing, the unit simplifies installation inside decentralized automation cells. It is intended to position or regulate mechanical axes in industrial machines that rely on distributed motion control over Ethernet-based field networks.

Electrical power is supplied by a DC 750 V link, allowing the internal inverter stage to deliver rated torque without an individual AC mains connection. A single Hybrid Connector carries both power and communication signals, which reduces external wiring. Heat is removed by natural convection, so no additional fans or liquid circuits are necessary if ambient air can flow freely around the enclosure. The motor section is built as an ATEX version, enabling use in zones where potentially explosive atmospheres may be present. Motion commands and diagnostics travel over Multi-Ethernet, giving the drive access to EtherNet/IP, PROFINET, and EtherCAT topologies through the same port. The design is version 1 with a basic performance level, and it is supplied without a holding brake, so external mechanical restraints must secure vertical loads when power is off.

Position feedback relies on a Hiperface interface that links the controller to an optical sensor capable of 128 signal periods per mechanical revolution. The multi-turn absolute feature retains shaft position through power cycles. Functional safety is implemented through Safe Torque Off (STO), which removes drive energy without interrupting fieldbus communication. A shaft seal is fitted, and the plain shaft output matches couplings that do not need keys. The motor has size 041 and length C, while the winding code is 42. The unit is in series 2.
