Product Description:

The KSM02.1B-041C-42N-M1-HG2-ET-S3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor, encoder, and inverter in one enclosure, it drives decentralized machine axes without a cabinet-mounted controller. This integrated layout reduces external wiring between the motor and drive section and supports compact machine designs. The unit is series 2, uses design version 1, and is intended for the basic performance level used in packaging, printing, and material-handling systems.

Electrical power reaches the unit through a DC bus rated at DC 750 V, which helps keep current low and cabling compact. Control traffic is handled by the Multi-Ethernet interface, allowing integration with EtherNet/IP, PROFINET, or EtherCAT networks. Heat is removed by natural convection, so the housing should remain unobstructed to allow air to rise past its fins. Position feedback is transmitted over a Hiperface connection from the optical multi-turn absolute encoder. The internally mounted brake is electrically released and is energized with DC 24 V to secure the load during power loss. Power, signal, and brake conductors share a hybrid connector, which helps reduce cable routing complexity around the axis.

Precision is supported by an encoder resolution of 128 signal periods, enabling fine interpolation inside the servo loop. The motor section is size 041 with length code C, which provides moderate torque while keeping the footprint compact. A plain shaft with a shaft seal helps prevent grease leakage and blocks contaminants from entering the bearing area. Functional safety is provided through Safe Motion (without SBC), allowing safe-stop and speed-limited operation without additional sensors. Winding code 42 identifies the stator layout matched to the drive’s basic rating, and the hybrid connector carries both power and Ethernet to simplify setup.
