KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-35N-M1-HP0-ET-S3-D7-TO-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 servomotor, power electronics, and a fieldbus interface in one housing, the unit provides decentralized motion control for packaging stations, material-handling axes, and other distributed machines. It draws power from a shared DC bus, closes its current and speed control loops, and returns position data to the controller. This integrated arrangement reduces the amount of cabinet wiring required in industrial automation cells.

The electrical input is DC 750 V, allowing the drive to connect directly to an IndraDrive supply bus without an individual rectifier. Heat dissipation relies on natural convection, so the installation must provide adequate airflow and maintain the permitted ambient temperature. A single hybrid connector carries power, feedback, and Ethernet connections, simplifying cable routing through the machine. Design level 1 indicates the mechanical revision used for this unit. Integrated Safe Motion functions provide safe torque off and safe speed monitoring without an additional safety bus coupler. The motor has frame size 061 and frame length C. Its keyed shaft includes a shaft seal that protects the bearing area from contaminants. The unit is supplied without a holding brake, so an external mechanism must retain static loads when power is removed.

Control networking is provided through the Multi-Ethernet interface, which supports real-time protocols such as Sercos over Ethernet without an option card. Rotor position is measured by a Hiperface encoder that uses optical scanning and records multi-turn absolute position data. The encoder provides 128 signal periods per revolution, supporting precise axis synchronization and accurate position control. Winding code 35 identifies the electrical characteristics used by the matching drive controls and corresponds to the Basic performance class. The shaft keyway provides positive torque transmission to a pulley, coupling, or gearbox. The product uses Series 2 hardware and supports consistent drive parameters across coordinated machine axes.
