KSM02.1B-071C-35N-M3-HG2-ET-L3-D7-NN-FW

The Bosch Rexroth Indramat KSM02.1B-071C-35N-M3-HG2-ET-L3-D7-NN-FW is a high-performance member of the KSM Motor Integrated Servo Drives series that integrates a precision servo motor and drive control electronics within a single housing. This Motor-Integrated Servo Drive platform delivers compact motion control with simplified installation, reducing cabling and footprint requirements. The unit features a fully integrated drive controller and a native Master Communication Protocol of Multi-Ethernet, supporting seamless communication in automated environments. With a Supply Voltage of DC 750 V and a robust Connection Type via Hybrid Connector, this model is engineered for reliable power transmission and signal integrity. The design also incorporates Natural convection cooling, eliminating the need for auxiliary fans and enhancing system reliability in dust-sensitive applications.

Detailed technical specifications underscore the module’s precision and robustness. The integrated encoder employs Capacitive technology with Multi-turn absolute sensing, offering 16 signal periods of resolution over an indefinite turn range. A Plain shaft design with Shaft Seal protection ensures contamination resistance and long-term mechanical stability. The motor section, size 071, uses a Winding Code of 35 and a motor length designated as C, providing balanced torque production and inertia for dynamic response. The electrically released holding brake operates at DC 24 V, delivering secure axis hold without external brake power modules. The product adheres to Performance Level Basic and incorporates Safe Torque Off (STO) safety technology, facilitating rapid shutdowns and compliance with functional safety standards.

Operational features enhance performance across a range of motion control tasks. The Natural convection cooling design maintains optimal thermal conditions up to rated loads without increased acoustic noise. The Hybrid Connector simplifies wiring by combining power and communication conductors in a two-in-one interface, reducing installation time and potential wiring errors. Multi-Ethernet communications support real-time control loops and distributed I/O integration, enabling synchronized motion across multiple drives. The capacitive Hiperface encoder interface ensures low-latency, jitter-free feedback for precise speed and position control. The holding brake, with its Electrically Released mechanism, prevents unintended motion during standstill or power loss conditions.

Integration into larger automation systems is straightforward via standardized interfaces and safety features. The built-in Safe Torque Off (STO) function allows direct connection to safety controllers without external relays. As a single-unit solution, the drive reduces cabinet space and cable routing complexity, making it ideal for compact machines, conveyors, packaging lines, and assembly cells. Designed for engineering environments requiring high reliability and precise motion, the KSM02.1B-071C-35N-M3-HG2-ET-L3-D7-NN-FW is a versatile choice for OEMs and system integrators targeting efficient, space-saving automation solutions.
