Product Description:

The KSM02.1B-071C-24N-M1-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 the servomotor, power stage, and fieldbus electronics in one enclosure, the unit delivers distributed motion for assembly cells and material-handling stations while eliminating long motor cables and centralized drive cabinets. This layout places the drive electronics directly at the axis, which helps reduce panel space and shortens the path between the inverter and the motor windings. The encoder is optical and provides multi-turn absolute position sensing, so homing is unnecessary after power loss.

This drive accepts a bus link of DC 750 V, which feeds the inverter section that generates three-phase stator currents. Heat from these power electronics is removed by natural convection, so no auxiliary fans are needed in sealed installations. Power, feedback, and I/O are routed through a single Hybrid Connector, which simplifies installation on moving carriages. Multi-node coordination is handled through the Multi-Ethernet interface, which supports Sercos III, EtherNet/IP, PROFINET, and EtherCAT without extra hardware. Position feedback comes from a Hiperface optical encoder that delivers 128 signal periods per mechanical revolution, allowing fine velocity control at the controller. The device uses the standard design option with design version 1, winding code 24, the basic performance level, and Series 2.

The mechanical section features a plain shaft in size 071, suitable for clamp or keyed couplings. A holding brake that is electrically released engages automatically when the 24 V DC supply is removed, securing vertical loads. The brake coil shares the main auxiliary DC 24 V supply. The motor has length C, and a shaft seal is fitted to protect the front bearing. The plain output shaft eases coupling to gearboxes or timing pulleys without backlash inserts.
