Product Description:

The KSM02.1B-041C-42N-S1-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. Combining power electronics, feedback, and a servomotor in one enclosure, the device simplifies cabinet wiring and supports decentralized installation. It delivers closed-loop position and velocity control for packaging machinery, assembly cells, and material-handling axes where short cable runs and compact footprints are desirable. Because the inverter and motor are housed together, the axis can be installed closer to the moving machine section without a separate cabinet-mounted amplifier at the motor location. The combined layout also reduces the number of separate axis components mounted near the machine.

Electrical power is supplied on a single DC bus rated at DC 750 V, enabling energy sharing among multiple axes. A hybrid cable terminates at the factory-installed Hybrid Connector, carrying power, Ethernet, and safety conductors in one sheath. Heat from the integrated inverter is removed by natural convection, so no fans are required. Control data reach the unit through its Multi-Ethernet master interface, which supports PROFINET, EtherNet/IP, and EtherCAT without hardware changes. This allows the same drive hardware to fit different controller environments. Rotor position is measured by a Hiperface optical encoder that resolves each turn into 128 signal periods. Encoder feedback is used for commutation and for maintaining stable speed and position regulation during operation. The unit is design version 1, uses the standard mechanical option, and is in series 2 of the KSM line.

The integrated holding brake is electrically released and operates on DC 24 V, securing the axis whenever control power is lost. A shaft seal is fitted, and torque is delivered through a plain shaft suited to couplings or pulleys. That arrangement is useful where the axis must remain stationary after power is removed. The motor section combines winding code 42 with size 041 stator laminations and length C to balance torque density with convection cooling. The feedback system is single-turn, so it reports absolute position within one mechanical revolution.
