Product Description:

The KSM02.1B-041C-42N-M3-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with integrated power electronics, it removes the need for separate drive cabinets and keeps wiring short in decentralized automation zones. The unit supplies closed-loop position, speed, and torque control for conveyors, pick-and-place modules, and other motion tasks that demand compact, distributed actuation. This arrangement suits machine sections where the axis module must be mounted close to the driven mechanism and cabinet space is limited.

Electrically, the drive is supplied from a shared intermediate circuit at DC 750 V. A single Hybrid Connector carries power, fieldbus, and encoder lines, which simplifies cabling. Heat is removed through natural convection, so the housing must remain unobstructed for effective airflow. Position data are delivered via Hiperface, and the capacitive sensor generates 16 signal periods per revolution; internal interpolation provides finer feedback for stable servo response. Winding code 42 with motor size 041 and length C identifies the electromagnetic combination used in this unit, and the lack of a holding brake reduces rotating inertia on fast-cycling axes.

On the communication side, the controller supports Multi-Ethernet, allowing protocol selection among EtherCAT, PROFINET, or SERCOS III by parameter setting alone. The integrated functional safety function is Safe Torque Off (STO), which removes gate signals to the inverter stage. The encoder stores position across power cycles as a Multi-turn absolute value, which eliminates homing routines after restart. A sealed housing with a shaft seal protects internal components, and the Plain shaft eases coupling to gearboxes or pulleys. The unit is design version 1, uses the standard mechanical option, belongs to series 2, and has a basic performance level.
