Product Description:

The KSM01.2B-071C-35N-S1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. This self-contained unit combines a permanent-magnet servomotor, power electronics, and a fieldbus interface in one housing. It provides decentralized axis control for compact machinery and material-handling cells. By integrating the drive electronics with the motor, the unit reduces the number of separate cabinet components needed for an axis. This arrangement is useful where machine layouts require short cable runs and compact installation space.

The drive receives power from a bus supply rated at DC 750 V and dissipates heat through natural convection, eliminating the need for external fans or liquid circuits. Power, signal, and safety wiring are grouped in a single Hybrid Connector, which keeps the connection layout compact and simplifies cable routing. Position feedback is delivered through a Hiperface optical encoder that resolves motion over 128 signal periods, supporting precise velocity and position control during indexing and repeated positioning moves. An internal shaft seal helps retain lubricant at the gear interface. The cooling method suits installations where clean airflow around the housing is available.

Communication to the machine controller runs over SERCOS 2 (RS422), allowing deterministic cycle times and parameter access through a serial interface. The encoder is a single-turn type, so absolute position is retained within one mechanical revolution. A plain shaft exits the front flange for direct coupling to precision gearheads, and the motor frame size is 071. The unit has no integrated brake, so holding tasks must be handled by drive torque or an external clamp. This layout is suited to axes that use direct couplings or compact gearheads and do not require a built-in holding brake.
