KSM02.1B-061C-61N-S3-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-S3-HG2-ET-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining power electronics, feedback, and motor components in one housing, the unit mounts directly on a machine axis, reducing cabinet wiring and simplifying decentralized motion control in automated production lines. It accepts a bus supply of DC 750 V, which feeds the integrated inverter stage that modulates stator current according to motion commands.

Power, signal, and brake conductors are consolidated in a hybrid connector, limiting enclosure penetrations to a single multicore cable. Heat generated by the drive is dissipated through natural convection, so no fans or liquid circuits are required around the actuator. Networked control data travel over the Multi-Ethernet interface, allowing parameter access through several real-time Ethernet protocols without hardware changes. An electrically released brake clamps the rotor when inactive, and its coil is energized at DC 24 V to release the load during operation. The unit has the Standard design option and design version 1, and it is a Basic performance model in Series 2.

Position feedback is generated by a Hiperface encoder that uses 16 signal periods per mechanical revolution. The underlying sensor is capacitive, providing immunity to magnetic contamination. The single-turn format delivers absolute position for one revolution, which is sufficient for many rotary axes. Drive torque is transmitted through a plain shaft, and a shaft seal protects the internal bearings from lubricant washout and particulates. Motor size 061 with length code C provides torque capacity for mid-frame packaging machines, while winding code 61 matches the stator impedance to the integrated power stage. Safety technology is not included, so external safety measures are required when the application needs functional safety.
