KSM01.2B-071C-24N-M1-HP0-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-071C-24N-M1-HP0-SE-NN-D7-NN-FW is produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines a permanent-magnet servo motor, power stage, and control interface in a single housing, allowing motion axes to be mounted directly on the machine frame without a separate control-cabinet drive. In industrial automation, this arrangement reduces cable runs and minimizes electromagnetic coupling while providing closed-loop speed and position control for packaging stations, pick-and-place gantries, and small transfer units. The integrated design also reduces the number of separate components required around each controlled axis.

The drive section draws power from a DC 750 V intermediate circuit and distributes it internally to the stator windings with code 24. All motor and fieldbus conductors enter through a single hybrid connector, reducing installation time and the likelihood of wiring errors. Thermal energy is removed by natural convection, so the unit must be mounted where vertical airflow can pass across its cooling fins. Command and diagnostic data travel over SERCOS 2 at the RS-422 level, providing deterministic cycle times suitable for coordinated multi-axis motion. The unit has a motor size of 071 and a stack length code of C, creating a compact format for installations with limited space.

The position loop uses a Hiperface feedback port that reads an optical disc with 128 signal periods per mechanical revolution. Its multi-turn absolute encoder reports the shaft position across multiple revolutions without battery backup, reducing the need for homing routines after a power interruption. Mechanical output is delivered through a shaft with a keyway, allowing secure coupling to timing pulleys or gearboxes. An integrated shaft seal protects the front bearing from emulsified coolants and other contaminants near the driven connection. The module has a basic performance level and is supplied without a holding brake. It also has no dedicated safety technology, so any required safety functions must be provided by external equipment.
