Product Description:

The KSM02.1B-071C-24N-M1-HP0-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. This unit groups the power stage and control electronics directly on a size 071 synchronous motor, forming a compact axis for distributed automation. By combining drive and motor, it supplies decentralized torque and speed control to packaging, handling, and assembly stations while reducing cabinet wiring in compact machine layouts.

Electrical power is supplied through a DC 750 V internal bus, and field wiring is consolidated in a Hybrid Connector, so power, signals, and network lines reach the drive on a single plug. Heat is removed by natural convection, eliminating fans and allowing the housing to mount directly on machinery without forced airflow. Real-time control data are exchanged over Multi-Ethernet, which covers EtherNet/IP, PROFINET, and EtherCAT from the same port. For functional safety, the integrated Safe Torque Off (STO) circuit disables energization of the windings when the safety channel is opened. The motor section follows length code C and winding code 24, matching medium-inertia loads at the rated bus voltage.

Position feedback relies on a Hiperface optical encoder that delivers 128 signal periods per revolution and stores an absolute position over multiple turns; the multi-turn absolute capability removes the need for homing after power loss. Because the unit ships without a holding brake, external restraints or drive torque must secure vertical loads when power is removed. A shaft with keyway transfers torque, and the shaft seal helps limit ingress where lubricants or coolants are present. The servo belongs to series 2, and optical scanning inside the encoder maintains resolution independent of wear during repeated operating cycles.
