Product Description:
The KSM02.1B-041C-42N-M3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. By combining a synchronous motor, power electronics, and feedback into one housing, this unit streamlines installation on distributed machine axes and minimizes cabinet wiring. It is used in industrial automation to deliver closed-loop positioning and velocity control for packaging stations, pick-and-place heads, and light material-handling modules.
The drive accepts a DC 750 V supply bus and routes both power and signal lines through a Hybrid Connector, so only one cable is needed between the control panel and the motor. Internal power electronics are cooled by natural convection, eliminating forced-air hardware in tight enclosures. Position feedback arrives over the Hiperface interface, where a capacitive sensor delivers 16 signal periods per revolution. This resolution supports smooth interpolation at low speeds. Winding code 42 is matched to the integrated inverter to provide rated torque within the Basic performance class, and the size 041 stator is packaged in motor length C. Design version 1 uses the standard mechanical layout of series 2 units.
An electrically released holding brake rated at DC 24 V secures the axis when power is off and disengages automatically during motion commands. Functional safety is integrated through Safe Torque Off (STO), allowing energy isolation without mechanical uncoupling. For higher-level coordination, the integrated controller exchanges cyclic data over Multi-Ethernet, covering EtherNet/IP, PROFINET, and EtherCAT through the same interface. The multi-turn absolute encoder remembers position after shutdown, its capacitive technology resists magnetic fields, and the shaft seal prevents coolant ingress along the keyed shaft.
