Product Description:

The KSM01.2B-041C-42N-S1-HG2-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining inverter electronics and a synchronous motor in one enclosure, the unit provides closed-loop motion control for pick-and-place modules, conveyors, and indexing tables in automated equipment. Because the power stage and motor share the same housing, the axis can be mounted close to the driven load and uses fewer separate components than a cabinet-based drive arrangement. The unit uses motor size 041 with length code C, belongs to series 1, and is design version 2 in the standard design.

Power for the drive section is supplied from a DC 750 V bus, and energy enters through a Hybrid Connector, so power, control, and feedback lines are grouped at one connection point. Heat is removed by natural convection, so the housing can be mounted on the machine when surrounding air can circulate freely around the surface. This cooling method avoids auxiliary fans and keeps the installation layout simple. Axis feedback is provided by a Hiperface optical encoder with 128 signal periods per revolution, and the single-turn format reports position within one mechanical turn. Winding code 42 matches the electrical characteristics of the motor section to compatible power supplies, and a shaft seal is fitted at the motor nose to help limit contamination ingress.

An electrically released brake provides holding force when the unit is de-energized and disengages at DC 24 V. This brake arrangement helps keep the axis in place when motor torque is not available, which is useful on vertical or suspended loads. Network communication is handled through SERCOS 2 (RS422), which supports cyclic command exchange and synchronized status data with the higher-level motion system. The motor uses a plain shaft for direct coupling to external hubs or clamping elements. The unit is supplied without integrated safety technology, so emergency-stop or safe-torque-off functions must be provided by the machine control system.
