Product Description:

The KSM02.1B-041C-42N-S1-HG2-ET-L3-D7-AE-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining power electronics, feedback, and a synchronous motor inside one housing, it provides decentralized axis control for conveyors, handling modules, and other automation stations where cabinet space is limited. The integrated layout places the inverter directly at the machine axis, which helps reduce motor cable runs and supports compact machine designs. It is intended for decentralized motion nodes that use shared power distribution and network-based control on the machine.

This unit connects to field wiring through a single hybrid connector that carries DC bus, control, and network lines. Heat generated by the drive is removed through natural convection, so no fans are required. A bus voltage of up to DC 750 V supplies the inverter section, while an electrically released brake is powered by a DC 24 V line and holds the load when the coil is de-energized. Position feedback is delivered over the Hiperface interface, giving 128 signal periods per motor revolution for closed-loop control. Design version 1 uses motor size 041, length C, and winding code 42 for medium-torque tasks.

Functional safety is addressed by the integrated Safe Torque Off channel, which removes drive power without requiring a separate drive package. Real-time command data travels over Multi-Ethernet, enabling direct connection to EtherCAT, PROFINET, or EtherNet/IP masters used elsewhere in the machine. The encoder uses optical sensing in a single-turn arrangement, so one mechanical revolution resets the absolute position count. A plain shaft simplifies coupling to gearboxes, and a shaft seal is fitted to help protect the bearing area from contaminants. Because the drive, brake, and feedback functions are integrated, only one device needs to be mounted at the axis.
