KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By integrating drive electronics with a permanent-magnet synchronous motor, it reduces cabinet wiring and shortens feedback loops in distributed automation systems. The unit is intended for indexing tables, packaging axes, and handling modules that need compact motion control close to the load.

The drive section accepts a bus voltage of DC 750 V, so it can connect directly to high-energy intermediate circuits in modular machine platforms. Heat is removed by natural convection, eliminating fans and allowing installation inside sealed machine frames. Network traffic is carried over Multi-Ethernet, and the onboard switch supports several real-time Ethernet protocols without additional hardware. Position feedback travels from an optical multi-turn encoder through the Hiperface interface. The encoder delivers 128 signal periods per mechanical revolution and provides absolute position information over 4,096 turns. Motion characteristics correspond to the product's basic performance level, aligning its continuous torque and dynamic response with midrange handling tasks. The unit uses design version 1 and the standard mechanical option. Winding code 42 pairs the stator with the appropriate drive parameters for a Series 2 motor with size 041 and length C.

Power and signal conductors terminate in a hybrid connector that carries DC-bus power, safety I/O, and Ethernet through a single plug, simplifying installation. Functional safety is provided by Safe Motion with SBC, enabling safe torque off and safe stop functions without external relays. The rotor must be secured by external mechanical equipment because the unit is supplied without a holding brake. Output torque is transmitted through a shaft with a keyway, which provides positive engagement with a compatible coupling or driven component. A shaft seal is fitted to limit contaminant ingress when the motor is installed in washdown areas.
