Product Description:
The KSM02.1B-071C-35N-M1-HG2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining drive electronics and a synchronous servomotor in one housing, the unit decentralizes axis control and reduces cabinet wiring in automated assembly cells, packaging machines, and material-handling gantries. It belongs to revision 2 of the family and has a basic performance level.
The motor has size 071 and length C, giving moderate torque for mid-range actuators. Power, feedback, and brake circuits enter through a single Hybrid Connector, which minimizes connector count. Heat is removed by natural convection, so no forced airflow or liquid cooling infrastructure is required. Position data travels over the Hiperface encoder interface, and the optical sensor delivers 128 signal periods per motor revolution for fine interpolation inside the integrated drive. An electrically released brake rated at DC 24 V secures loads during power-off. The assembly uses the standard design option in design version 1.
Control and bus power share a common supply rail of DC 750 V, derived from the central converter. Real-time motion commands reach the device through the Multi-Ethernet master interface, enabling compatibility with EtherNet/IP, EtherCAT, PROFINET, and SERCOS over the same port. The mechanical output exits on a plain shaft with an integral shaft seal, which helps keep lubrication in place against dust or splash. Electromagnetic characteristics follow winding code 35, which matches the integrated inverter rating and sets the current and voltage limits for the stator. A multi-turn absolute optical encoder reports axis position across 4096 turns, eliminating homing sequences after shutdown. Mounting orientation should allow vertical airflow paths to preserve the specified temperature rise.
