Product Description:

The KSM02.1B-041C-42N-S1-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive engineered by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. Version 1 combines the drive electronics with a size 041 stator and a length C housing, so the motor and controller mount as a single unit on the machine. Classified at the Basic performance level, it is intended for positioning tasks that do not require extended option packages, and its Multi-Ethernet interface links directly to PLC networks for coordinated motion. This integrated format keeps the axis package compact on the machine frame and reduces the need for separate drive hardware nearby.

The electrical stage is fed from a DC 750 V intermediate circuit and is matched to winding code 42 for this bus level. Power, feedback, and fieldbus lines are combined in a Hybrid Connector, which reduces cabinet wiring to a single molded plug. Heat from the inverter and stator is removed through natural convection, so no external fan or liquid loop is required. Functional safety is provided by Safe Torque Off (STO), which removes drive energy without opening the main relay. Position feedback uses a Hiperface interface that carries incremental and absolute data, and its optical sensor produces 128 signal periods per motor revolution to support precise commutation. A shaft seal is fitted to help block contaminants at the coupling point during routine operation.

The drive is in series 2 and has a plain shaft for clamp or taper couplings. It is supplied without a holding brake, so stationary load support must come from drive torque or external calipers. The optical feedback device is single-turn, which means absolute position is retained within one rotation while additional revolutions are tracked by the controller counter. The sealed front bearing helps reduce contaminant entry around the drive end during normal factory operation.
