KSM02.1B-071C-24N-S1-HG2-ET-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-071C-24N-S1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, drive electronics, and feedback inside one housing, it simplifies wiring and reduces cabinet space in distributed automation systems. The unit mounts directly on a machine axis and accepts high-speed command data from the plant network to position loads, making it suitable for material-handling, packaging, and pick-and-place stations that require precise and compact motion modules.

A single Hybrid Connector carries incoming DC bus power, control I/O, and network signals, so only one cable bundle is routed to the axis. The power stage is rated for a DC 750 V supply, allowing the servo to share a common DC link with other drives on the line. Heat is removed through natural convection, so no fans are required when the drive is installed in a properly ventilated enclosure. Motion commands are transferred through a Multi-Ethernet interface that supports PROFINET, EtherNet/IP, and SERCOS III without changes to the physical interface. Position holding during power loss is provided by an electrically released brake energized at DC 24 V, allowing vertical axes to remain locked when bus power is removed.

Rotor position feedback uses the Hiperface protocol, and the optical encoder delivers 128 signal periods per revolution for precise speed regulation. The drive uses the 071 frame size, providing a moderate flange dimension that pairs with midrange gearboxes while keeping inertia low. It has a Basic performance level and does not include integrated safety technology. A plain shaft with a factory-installed shaft seal helps prevent lubricant leakage and protects the shaft interface from contamination. The C-length stator uses winding code 24 to provide continuous torque for medium-duty cyclic motion profiles.
