Product Description:

The KSM02.1B-041C-42N-M1-HG0-ET-SD-D7-ES-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with built-in drive electronics, it streamlines cabinet wiring and suits distributed motion axes on packaging, handling, and assembly lines. The drive accepts a DC bus feed and executes closed-loop position and velocity tasks directly on the machine, reducing panel heat and field cabling compared with conventional drive-motor pairs.

A single cable system terminates in a Hybrid Connector that carries power, signals, and safety wiring. Internal losses are removed through natural convection, so no fans are installed and the mounting orientation must allow free airflow around the housing. The power stage is rated for a DC 750 V intermediate circuit, matching common Rexroth supply modules. Position feedback comes from an optical encoder that communicates via Hiperface. Its rotor count mechanism uses multi-turn absolute feedback, enabling power-off position retention for homing-free restarts. Mechanical output is provided by motor size 041 with length C, and the unit is supplied without a holding brake to keep weight and inertia low.

The Safe Motion (with SBC) package enables drive-level STO, SOS, and speed monitoring for PL e applications without extra relays. Torque is transmitted through a plain shaft with an integral shaft seal, helping maintain ingress protection when the unit is flange mounted. Electromagnetic behavior is set by winding code 42, which matches the current density of the drive's Basic performance level and Series 2 design. The optical sensor delivers 128 signal periods per mechanical revolution before interpolation. Multi-Ethernet provides the external master communication option, allowing connection to Sercos III, EtherNet/IP, or PROFINET networks.
