Product Description:
The KSM02.1B-041C-42N-M1-HG2-ET-SD-D7-ES-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet synchronous motor with decentralized drive electronics, it supplies compact axis control for packaging, material-handling, and assembly stations. The device is intended to be mounted close to the load so that it reduces cabinet wiring and supports distributed motion tasks within automated production lines. This arrangement also shortens the connection path between the drive electronics and the motor section during normal machine operation.
The drive receives its DC bus through a Hybrid Connector that carries power, communication, and brake lines, and it operates from a regulated bus of DC 750 V supplied by the central converter. Heat is transferred to the ambient air by natural convection, allowing operation without forced airflow and avoiding the need for separate fan hardware. Position feedback is handled by a Hiperface optical encoder that offers 128 signal periods per mechanical revolution and provides multi-turn absolute data for accurate homing. An electrically released holding brake is energized at DC 24 V, enabling load retention during power-off events. The motor has size 041 and length C, while the plain shaft is protected by a shaft seal that helps limit dust and moisture entry at the output end. Performance level is designated as Basic, and the build corresponds to design version 1.
Control integration is completed through the external master communication option, where the unit exposes a Multi-Ethernet interface so one hardware configuration can communicate with different Ethernet-based controllers used in machine automation. Functional safety is addressed by the embedded Safe Motion (with SBC) package, which adds supervised braking and speed monitoring inside the drive without extra relays. Electrical characteristics are set by winding code 42, and the unit is part of series 2 in the KSM family.
