Product Description:

The KSM02.1B-041C-42N-S1-HG2-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor, drive inverter, and I/O in one enclosure, the device is installed directly on moving axes. This arrangement shortens power runs, lowers panel heat, and supplies position-controlled torque for pick-and-place gantries, palletizers, and small conveyor modules. It supports decentralized machine architectures where servos are mounted close to actuators, simplifying wiring topologies.

The drive accepts a bus supply of DC 750 V, allowing multiple axes to share a common intermediate circuit and return energy to the supply. Field wiring is routed through a Hybrid Connector, so power, safety, feedback, and Ethernet all pass through one plug, reducing wiring complexity. Heat generated by the inverter is removed by natural convection, permitting fanless operation when the unit is bolted to a grounded machine plate. Rotor position is measured by a Hiperface encoder that delivers 128 signal periods per mechanical revolution; this combination supports smooth commutation and electronic nameplate data for automatic parameter loading.

An electrically released brake energized by DC 24 V keeps the shaft locked during power loss and releases automatically when torque commands resume. For functional safety, the power stage integrates Safe Torque Off (STO), enabling shutdown without external relays. Motion commands and diagnostics travel over Multi-Ethernet, letting the same hardware join Sercos III, PROFINET, EtherNet/IP, or EtherCAT networks. Magnetic characteristics are matched to medium-inertia tasks by winding code 42, while size code 041 with a plain shaft and a shaft seal allows direct coupling to timing-belt pulleys or gear inputs.
