Product Description:
The KSM02.1B-041C-42N-M3-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 decentralized inverter in one enclosure, it delivers closed-loop positioning directly on the machine axis. This reduces cabinet wiring and shortens installation for conveyors, gantries, and pick-and-place stations in industrial automation. The integrated layout places the drive electronics close to the load, which helps simplify machine routing and keeps the axis package compact.
It operates from a bus voltage of DC 750 V, which the internal power stage converts into three-phase excitation for motion generation. Heat leaves the housing through natural convection, so no fan or coolant circuit is needed. A single hybrid connector carries power, encoder, and network conductors, reducing cable complexity. Command data moves through a Multi-Ethernet interface that supports several real-time fieldbuses without extra option cards. With its compact 041 motor size and length code C, the unit occupies minimal space. It uses a shaft with keyway to transmit torque, and a shaft seal is fitted to limit lubricant ingress. Because it is supplied without a holding brake, external locking devices must secure vertical or suspended loads.
Position feedback is supplied by a Hiperface multi-turn absolute encoder that relies on capacitive sensing and outputs 16 signal periods per revolution for interpolation. This encoder arrangement provides absolute position information after startup and supports consistent motion control on distributed axes. Functional safety is provided by Safe Torque Off (STO) channels that can remove drive energy without opening the DC link. The winding code 42 matches the drive's electrical constants to the motor configuration. The Basic performance level balances cycle time with current demand during operation, and the unit is built in series 2.
