Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-S3-D7-NN-FW is manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. It combines a size 041 servo motor with decentralized drive electronics, allowing the unit to mount directly on machinery without a separate control cabinet. Version 1 uses the standard design, and the C motor length with winding code 42 suits the required torque range for compact motion axes. The unit operates without a holding brake, so applications that need static load retention must use an external mechanical device. A fitted shaft seal helps limit fluid ingress during washdown service and supports use on machinery exposed to routine cleaning.

The drive is supplied from a DC 750 V power bus and removes heat through natural convection, so no fan is required during operation. All power, feedback, and safety conductors terminate in a single Hybrid Connector, which helps reduce cable quantity and simplifies routing on modular equipment. Position feedback reaches the controller through a Hiperface interface that supports automatic electronic nameplate reading and stable servo control. On the control side, the device communicates with PLCs over Multi-Ethernet, allowing use with EtherNet/IP, PROFINET, or EtherCAT without a hardware change. This communication and connection layout fits decentralized axes used in conveyor, packaging, and assembly systems.

An optical encoder delivers 128 signal periods per mechanical turn and stores position through its multi-turn absolute capability, so the axis can restart without a homing cycle after power loss. Drive-integrated safety meets Safe Motion without SBC requirements, enabling functions such as safe torque off through the same hybrid connection. Mechanical power is transferred through a shaft with a keyway, which provides positive engagement for couplings or pulleys. Stored position data helps the machine retain axis reference after normal shutdowns, and the keyed shaft supports secure torque transfer in repeated start-and-stop motion.
