KSM02.1B-061C-35N-M1-HP0-ET-L3-D7-T0-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP0-ET-L3-D7-T0-FW is a motor-integrated servo drive from the KSM Motor Integrated Servo Drives series produced by Bosch Rexroth Indramat. By combining a permanent-magnet servo motor, encoder, and power electronics in one enclosure, it simplifies wiring and cabinet layouts in distributed automation. The device supports precise positioning on packaging lines, assembly stations, and material-handling axes where decentralized control reduces panel complexity and shortens installation time.

The drive accepts a DC 750 V supply rail that is typically provided by a shared power module in multi-axis machines. Power, signal, and safety lines pass through a single hybrid connector, so only one cable must be routed along the machine frame. Heat is removed by natural convection, eliminating fans and permitting sealed mounting. Encoder feedback reaches the controller over the Hiperface interface, delivering absolute position data to the control system. Integrated Safe Torque Off (STO) supports machinery safety by disabling motor torque without external relays. The unit is supplied without a holding brake and has the Basic performance level. It has motor size 061, length C, design version 1, and winding code 35.

The encoder delivers 128 signal periods per mechanical revolution. Its multi-turn absolute feedback retains axis position across power cycles, while its optical sensing method avoids interference from nearby magnetic fields. Command data and diagnostics travel over the Multi-Ethernet interface, allowing PROFINET, EtherNet/IP, or EtherCAT to be selected through software. Motion is transmitted by a shaft with a keyway, providing positive engagement with a compatible coupling or driven component. A shaft seal helps protect the bearing package against contaminants. Locating the power electronics directly on the motor housing reduces the amount of wiring required between the drive, motor, and control cabinet.
