Product Description:

The KSM02.1B-061C-61N-S1-HG0-ET-SD-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, power electronics, and control logic in one enclosure, the unit can be mounted directly on machine axes, reducing cabinet wiring. It delivers closed-loop torque and speed control for conveyors, pick-and-place modules, and other automated stations that benefit from decentralized motion hardware. This layout keeps the drive close to the load, which can shorten motor cabling and simplify machine layouts with distributed moving axes.

The device is supplied from a bus voltage of DC 750 V, which the internal inverter converts into three-phase currents matched to winding code 61 of the 061-frame motor. Power, brake lines, and Ethernet signals are consolidated in a single Hybrid Connector, so only one cable set is routed through the machine. Heat is removed by natural convection; therefore, no fan or coolant circuit is required, and the housing must stay clear for airflow. Rotor position is detected by a Hiperface optical encoder that produces 128 signal periods per revolution, providing fine-grained feedback for smooth velocity regulation at low and high speeds.

Communication is handled through a master interface that supports Multi-Ethernet, allowing the axis to join PROFINET, EtherNet/IP, or EtherCAT networks without additional adapters. The feedback system measures position over a single-turn range, which suits applications that run a homing routine after power-up, and the plain shaft is protected by a positive shaft seal. The drive has a basic performance level for standard handling dynamics, while the integrated safety package labeled Safe Motion (with SBC) provides STO, SS1, and safe brake control without external relays. Because the unit is supplied without a holding brake, any static load retention must rely on external mechanical locking methods.
