KSM02.1B-071C-24N-S1-HP0-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-S1-HP0-ET-L3-D7-NN-FW is manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servomotor with decentralized drive electronics, the unit streamlines motion control on conveyors, gantries, and packaging stations where cabinet space and wiring effort must be minimized. It connects directly to a DC bus and mounts on the machine frame, delivering both torque generation and closed-loop control at the axis.

The drive section operates from a supply of DC 750 V, so it connects to high-power intermediate circuits without additional converters. Heat produced by the embedded power stage is removed through natural convection, eliminating fans and their maintenance requirements. Power, feedback, and fieldbus lines are routed through a single hybrid connector, simplifying cable management and reducing startup time. Rotor position is measured by an optical encoder that communicates through the Hiperface interface. Its resolution of 128 signal periods supports smooth velocity control and precise positioning for indexing tasks.

System integration is handled through Multi-Ethernet communication, allowing the unit to join EtherNet/IP, PROFINET, or EtherCAT networks without physical modifications. Functional safety is provided by Safe Torque Off (STO), which disables power to the motor windings when a safety input is triggered. Mechanical output is provided by a shaft with a keyway, giving positive engagement with pulleys or gearboxes. A shaft seal helps retain lubricants inside the housing and prevents contaminants from reaching internal components. The motor has a frame size of 071, which is suited to medium-torque applications. Its decentralized design leaves additional enclosure space for PLCs and I/O modules while shortening the motor cables required for installation.
