Product Description:

The KSM02.1B-071C-35N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat that belongs to the KSM Motor Integrated Servo Drives series. Because the power electronics are mounted directly on the servomotor, the product eliminates long motor cables and central drive cabinets. This layout suits distributed automation architectures that require precise position and speed control at the machine axis.

This drive is supplied from a bus voltage of DC 750 V, enabling it to share energy through common DC links in multi-axis systems. Command data reach the unit through the Multi-Ethernet interface, so the same hardware can participate in EtherNet/IP, PROFINET, or EtherCAT networks without hardware changes. Position feedback between the motor and controller is managed through the Hiperface interface, which supports electronic nameplate data and automatic parameter loading. The encoder signals pass through a single Hybrid Connector that also carries power, reducing the number of separate connections. Heat created by the embedded inverter leaves the housing through natural convection, allowing operation without fans or liquid cooling in sealed machine spaces.

The optical encoder provides multi-turn absolute position sensing, so power-off rotations are retained and homing routines are unnecessary. Each mechanical turn is subdivided into 128 signal periods, giving fine resolution for smooth servo loops. The motor section follows size code 071, which fits medium-torque requirements in packaging, handling, and small process lines. A plain shaft transmits torque without keyways, favoring backlash-free clamping couplings. The unit is supplied without a holding brake, so external mechanics or drive torque must maintain position during power loss, and the shaft seal helps protect the internal bearings against splash ingress in typical plant environments.
