Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-NN-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining drive electronics, fieldbus interface, and synchronous motor in one housing, it delivers decentralized motion control for conveyors, gantries, and packaging stations. The unit mounts directly on the machine frame and draws its DC bus power from a common supply, which suits modular production cells in industrial automation. Because the inverter and motor share one enclosure, the axis can be placed close to the driven mechanism without a separate motor cable between the cabinet and actuator.

The drive operates from a DC 750 V shared bus, so a single high-voltage pair feeds the controller and stator. Power, signal, and protective earth are grouped into a Hybrid Connector, simplifying installation and reducing wiring complexity. Heat is removed through natural convection, so no fans are required and enclosure integrity is maintained. Position feedback comes from a Hiperface optical encoder delivering 128 signal periods per revolution, and its single-turn design returns absolute position within one turn. The unit has frame size 041 and length C, and it is design version 1 with series 2. A shaft seal is present to guard against dust, and the unit is supplied without a holding brake for axes where static load is held by drive torque alone.

Multi-Ethernet connectivity, provided by the output-coupling design option, lets the axis use EtherNet/IP, PROFINET, or EtherCAT without changes to the drive hardware. The rotor uses a plain shaft, which works with clamp collars or shrink discs instead of keyed interfaces. Rated at the basic performance level, the unit uses winding number 42 to balance torque and speed for mid-range pick-and-place or indexing duties. This arrangement keeps the power stage close to the driven axis and leaves more cabinet space available for other automation components.
