Product Description:

The KSM02.1B-041C-42N-S3-HG0-ET-NN-D7-ES-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. It combines a synchronous servomotor, power stage, and network interface in one enclosure. This arrangement enables decentralized motion control on conveyors, pick-and-place gantries, and other automated stations where panel space and cabling length must be minimized. The compact layout places the drive electronics directly at the axis, which helps reduce the amount of separate cabinet hardware required on the machine.

This drive is supplied from a DC 750 V intermediate circuit and cools itself through natural convection, so no forced air or liquid lines are required in the machine frame. Power, feedback, and communication are routed through a single Hybrid Connector, which simplifies installation and supports daisy-chain layouts. Position feedback is handled by a Hiperface encoder interface that exchanges absolute angle data with the controller after each power-up. The electromechanical package uses the compact 041 motor frame size, which supports installation in tight mounting zones while keeping the overall footprint small.

The stator uses winding code 42, which matches drive current to the motor's thermal limits during operation. Its capacitive sensor delivers 16 signal periods per mechanical revolution for speed regulation, and the unit has a plain shaft for straightforward coupling to gearboxes or timing pulleys. The drive is supplied without a holding brake, so vertical loads require external retention when power is removed. The external master communication option allows connection to EtherNet/IP, PROFINET, or EtherCAT without hardware changes. An internal shaft seal helps limit dust ingress, the performance level is Basic, and integrated safety technology is not included.
