Product Description:

The KSM02.1B-061C-35N-S1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining the drive electronics with a 061 frame synchronous motor, it simplifies cabinet wiring and shortens installation time on modular machines. In packaging, printing, or material-handling cells, the unit supplies closed-loop torque and speed control directly at the axis, providing decentralized actuation for coordinated multi-axis motion.

The drive accepts a supply of DC 750 V, so it can be linked to a shared DC bus for energy exchange among axes. Power, feedback, and I/O reach the housing through a Hybrid Connector. This single plug carries motor phases, logic voltage, and real-time fieldbus lines, reducing connector count. Heat generated by the electronics is removed by natural convection, eliminating fans and the associated maintenance. Position feedback is handled by a Hiperface optical encoder that provides 128 signal periods per revolution, giving sufficient resolution for tight velocity loops at typical conveyor speeds. Design option standard and design version 1 indicate the standard configuration, while winding code 35 matches the magnetic circuit to the basic performance level used in the series 2 release.

A Multi-Ethernet master interface supports Sercos III, EtherNet/IP, or PROFINET communication through one connection. The encoder uses an optical scanning principle and is factory set as a single-turn device, so absolute position is retained across one revolution. Functional safety is provided through Safe Torque Off (STO), allowing category-based shutdown without removing the DC bus. Mechanical power is transmitted through a shaft with keyway, and a shaft seal limits grease egress and dust ingress. The motor length C stator and the absence of a holding brake make the unit suitable for horizontal axes that rely on external mechanics for load retention.
