Product Description:

The KSM02.1B-041C-42N-S1-HP0-ET-NN-D7-NN-FW belongs to the KSM Motor Integrated Servo Drives series from Bosch Rexroth Indramat. This motor-integrated servo drive combines a permanent-magnet motor and an electronic drive stage in one housing, allowing decentralized axis control in conveyor sections, packaging lines, and assembly stations. By placing the motor and drive together, it reduces separate cabinet hardware and supports compact machine layouts where distributed motion control is preferred.

Power enters the unit through a Hybrid Connector that carries the DC bus, control, and feedback lines in one plug, which simplifies wiring. The drive section operates from a DC 750 V supply, so it can share a common bus with other axes for energy exchange. Heat is removed by natural convection, so the housing uses cooling fins and should be mounted where free air can circulate around the enclosure. Rotor position is measured by a Hiperface optical encoder that provides absolute feedback with 128 signal periods per revolution, supporting stable velocity control. The encoder is single-turn, which is suitable for axes that do not need multi-turn position capture.

Fieldbus communication is handled by a Multi-Ethernet interface that supports Sercos III, EtherNet/IP, and PROFINET IO without additional hardware. Mechanical power is transmitted through a shaft with a keyway, and a shaft seal is fitted to help limit lubricant migration into the electronics area. The motor has a frame size of 041, and length code C places the active stack between the shorter B and longer D variants. Winding code 42 matches the integrated power stage for the intended electrical characteristics. The unit uses standard construction, design version 1, a basic performance level, no integrated safety technology, no holding brake, and internal classification series 2.
