Product Description:
The KSM02.1B-041C-42N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. Its integrated power electronics remove the need for a separate cabinet-mounted drive, allowing motion control to be mounted directly on moving axes. This configuration streamlines wiring in conveying, pick-and-place, and small-gantry systems where compact decentralized control is advantageous. By placing the inverter at the axis, the system shortens motor power paths and reduces the amount of cabinet hardware needed elsewhere in the machine.
The drive is supplied from a common DC link at DC 750 V, so the power section can be daisy-chained with other KSM devices without additional AC distribution. Power, safety I/O, and Ethernet are combined in a single Hybrid Connector, reducing cable runs to one umbilical. Heat generated by the inverter and motor is removed through natural convection, so no fans or liquid circuits are required. For networked operation, the controller supports Multi-Ethernet, allowing selection among EtherNet/IP, PROFINET, or Sercos over the same port. Torque production follows winding code 42, which identifies the stator resistance and inductance values used by the drive for rated current delivery.
Position feedback relies on a Multi-turn absolute optical encoder that provides 128 signal periods per revolution through the Hiperface interface, allowing tight velocity loops and eliminating homing after power loss. It uses an optical scanning principle that offers high signal fidelity in environments subject to electrical noise. A plain shaft in frame size 041 transmits torque, and an integral shaft seal helps block dust and coolant ingress. The housing uses motor length C and design version 1, and the unit is delivered without a holding brake or integrated safety functions. This arrangement fits compact axes where installation space around the carriage or tooling plate is limited.
