Product Description:

The KSM02.1B-041C-42N-M1-HP0-ET-SD-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. The unit combines a permanent-magnet synchronous motor with its own power stage and control electronics, allowing decentralized mounting directly on machinery. It executes velocity, torque, and position loops for individual axes in automated packaging, assembly, and material-handling cells. This arrangement places the inverter close to the driven mechanism, which supports compact machine layouts and shorter axis wiring.

As an electrically supplied device, the drive is fed from a DC 750 V bus shared with other axes, so no individual AC supply is required. Power, signal, and ground conductors enter through a single Hybrid Connector, reducing cable runs and keeping connections consolidated at the motor. Heat from the power stage leaves the housing by natural convection, eliminating fans for sealed installations. Control links to PLCs use the built-in Multi-Ethernet port that supports EtherNet/IP, PROFINET, and EtherCAT. Frame size 041 suits light conveyors and compact gantries. The unit uses a basic performance level, a standard design, Series 2, design version 1, and winding code 42.

An optical encoder using Hiperface provides 128 signal periods per turn and stores multi-turn data, so position is available immediately after power-up. The onboard safety package includes Safe Motion (with SBC), allowing certified velocity and position checks without external relays. Torque reaches the load through a shaft with a keyway, and a shaft seal helps limit fluid or dust ingress at the output end. Because the unit does not include a holding brake, static load holding must be provided by drive torque or an external lock during power loss. Motor length C keeps the housing compact while supporting responsive motion on short-cycle axes.
