Product Description:

The KSM02.1B-071C-35N-M1-HP2-ET-NN-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By placing the power stage and control electronics on the motor body, the unit reduces cabinet space and shortens field wiring while still supporting closed-loop torque and velocity control in packaging, handling, and assembly equipment. It operates from a common DC link and mounts directly on the machine frame, creating a compact motion node near the driven mechanism. This layout suits decentralized machine designs where the drive must be installed close to the axis instead of inside a separate enclosure.

Power reaches the drive through a single Hybrid Connector, and the internal inverter is energized from a DC 750 V bus. Heat is removed by natural convection, so no fan or liquid circuit is required. Control data travels over Multi-Ethernet, which allows connection to EtherNet/IP, PROFINET, and EtherCAT networks without an external protocol converter. Position feedback is handled through the Hiperface interface, where the optical encoder provides 128 signal periods per revolution and multi-turn absolute position retention after power is removed. That feedback gives the drive the rotor position information needed for closed-loop speed control and accurate positioning.

The brake is electrically released, and its coil operates from DC 24 V, so the shaft is held when control power is absent and released when the axis is enabled. A shaft seal helps protect the bearings against dust and splashes, and torque is transmitted through a shaft with a keyway for direct connection to pulleys or gearboxes. The motor uses frame size 071 with length C, giving it a compact envelope for direct installation on space-limited axes. Integrated safety functions are not included, so the stop function must be handled by external safety hardware.
