Product Description:

The KSM02.1B-041C-42N-S3-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 a permanent-magnet synchronous motor, power electronics, and fieldbus interfaces in one housing, it decentralizes motion control and reduces cabinet wiring in conveyor modules, form-fill-seal lines, and Cartesian pickers. Series 2 electronics and the standard design option place the unit in the current KSM product generation.

For power distribution, the drive accepts a supply of DC 750 V, matching intermediate-circuit buses used in multi-axis machines. Thermal limits are handled by natural convection, so no fans or coolant hoses are required. A single Hybrid Connector carries power, fieldbus, and brake conductors, reducing installation complexity and minimizing potential miswiring. Motion commands and diagnostics travel over Multi-Ethernet, allowing the same hardware to join Sercos III, EtherNet/IP, or PROFINET networks. When the axis must lock position, an electrically released spring-applied brake engages automatically once the 24 V control line is removed. This design version 1 unit has a Basic performance level for mid-range continuous duty.

Position feedback passes through Hiperface, and its encoder uses a capacitive scanning method that tolerates dust and vibration better than optical alternatives. With 16 signal periods per revolution and a single-turn data format, the controller always knows the rotor angle within one mechanical turn without relying on batteries. The 041 frame size and C length provide a compact footprint while accommodating winding code 42 for the required torque density. A plain shaft sealed at the factory prevents lubricant loss and keeps contaminants out, and the absence of integrated safety functions means external STO devices must be added where functional safety is required.
