Product Description:

The KSM02.1B-061C-35N-S1-HG0-ET-S3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It merges a synchronous motor with a regenerative inverter stage so the axis can be mounted directly on machines that use distributed Multi-Ethernet networks for coordinated motion. This configuration supports space-limited cells where localized control and reduced cabinet wiring are important in industrial automation. By placing the drive electronics at the axis, it also shortens motor cable runs and helps distribute control functions across the machine frame.

The unit accepts a supply of DC 750 V through a single power and signal line terminated with a Hybrid Connector. Internal heat is removed by natural convection, eliminating fans and lowering maintenance in sealed enclosures. Feedback is provided by a Hiperface interface that works with an optical sensing element delivering 128 signal periods per mechanical revolution, which maintains precise position data for the controller. The drive uses Multi-Ethernet for controller communication, allowing support for several Ethernet-based fieldbus formats without extra hardware. This arrangement helps the axis integrate with different control architectures while keeping the network connection decentralized.

Mechanically, the drive employs a plain shaft with a shaft seal to limit dust or fluid ingress. Functional safety is addressed by the Safe Motion package without SBC, enabling certified limit and stop functions through the bus. The actuator belongs to Motor Size 061, uses Motor Length C, and has winding code 35 to match its nominal torque profile. The unit is Series 2 with Design Version 1, and the performance level is Basic. It is supplied without a holding brake, so power-off load retention must be handled by external measures.
