Product Description:
The KSM01.2B-071C-24N-S1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat and assigned to the KSM Motor Integrated Servo Drives series. By combining an electronic drive with a permanent-magnet synchronous motor in one housing, it reduces cabinet wiring and shortens installation time in distributed automation cells. Its decentralized format lets the axis place power and motion control directly on moving assemblies, which keeps motor cabling short in packaging, material-handling, and assembly lines.
Power is delivered over a hybrid connector, which carries the DC supply, feedback, and fieldbus lines in one plug. The electronics operate from a bus voltage of DC 750 V, allowing several axes to share a common regenerative supply. Heat is removed by natural convection, so no fans or liquid circuits are required for the 071 frame. Rotor position is reported through a Hiperface optical encoder that provides 128 signal periods per revolution, which supports smooth velocity control. The mechanical section uses the standard design option in design version 2, while motor length C and winding code 24 identify the electromagnetic arrangement. Within the 071 frame size, this configuration meets the basic performance level for Series 1 devices.
The integrated control electronics communicate with the master via SERCOS 2 (RS422), providing cycle-synchronous setpoint exchange and diagnostic access. Because the encoder is single-turn, absolute position is available within one mechanical revolution, and external homing is required after each full rotation. Mechanical power is transmitted through a shaft with a keyway that is protected by a shaft seal against dust ingress. The drive is supplied without a holding brake, so vertical axes must rely on external locking or drive torque.
