Product Description:

The KSM02.1B-041C-42N-S3-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor and drive electronics, it decentralizes motion control and reduces cabinet wiring. The code 041C indicates size 041 with length C, and the unit uses a basic performance level for general-purpose positioning tasks. In automated assembly, packaging, or material-handling lines, the device provides closed-loop speed and position regulation directly at the axis while upstream controllers exchange real-time data on Ethernet networks.

Power, feedback, and safety conductors are routed through a single Hybrid Connector, lowering connector count and simplifying cable routing. The mechanical build follows the standard option and uses design version 1. Thermal energy leaves the housing by natural convection, eliminating the need for fans or liquid cooling but requiring unobstructed airflow. Position data is supplied by a capacitive, single-turn encoder that communicates over Hiperface and delivers 16 signal periods per mechanical revolution, supporting fine velocity control. For controller interoperability, the master interface supports Multi-Ethernet, so the same hardware can be configured for EtherNet/IP, EtherCAT, or PROFINET without rewiring.

The drive draws power from a shared DC bus rated at DC 750 V. Its internal stator, identified by Winding Code 42, matches this voltage so the size 041, length C motor can meet torque targets without saturation. Functional safety is addressed with Safe Torque Off (STO), which disables power to the phases while keeping fieldbus links active. The output end is a shaft with keyway; it is protected by a shaft seal and spins freely because this version is supplied without a holding brake. The unit uses a series 2 enclosure.
