Product Description:

The KSM02.1B-061C-35N-M1-HG0-ET-NN-D7-TO-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By placing the power electronics directly on the synchronous motor, the unit condenses axis control into a single housing for decentralized automation tasks. It is intended for positioning or velocity loops on conveyors, pick-and-place gantries, and other machinery that benefit from reduced cabinet space and simplified wiring.

This drive accepts a supply of DC 750 V, allowing it to tap the shared intermediate circuit of an IndraDrive system without an additional AC rectifier. Power, fieldbus, and safety lines are combined in the single Hybrid Connector, so only one cable is routed to the axis. Heat produced by both inverter and stator is removed through natural convection; no fan or liquid loop is required, which simplifies maintenance and reduces acoustic noise. Position feedback comes through a Hiperface interface that exchanges absolute data with the controller, while the optical scale delivers 128 signal periods per revolution, giving fine commutation and speed regulation at low rpm.

Communication and parameter access are provided over Multi-Ethernet, permitting the same hardware to run EtherNet/IP, PROFINET, or EtherCAT as dictated by the master. The integrated encoder is a Multi-turn absolute design, so the axis reports position after power cycling without a homing routine. Mechanical coupling is via a plain shaft sealed against dust and splash; the seal also keeps grease out of the motor chamber. With a frame size of 061, the basic performance class supports moderate continuous torque while staying compact. Because the unit is delivered without a holding brake and without dedicated safety functions, static loads and safe torque off must be managed through external means.
