Product Description:

The KSM01.2B-076C-35N-S1-HP2-SE-NN-D7-NN-FW is produced by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. In this mechatronic unit, the motor, feedback electronics, and drive inverter reside in a single housing, allowing decentralized installation on machine frames. The device is intended for positioning and velocity control of rotary axes in packaging, handling, and general automation lines where cabinet space and wiring complexity must be minimized. This integrated layout reduces the need for separate motor and feedback cabling between the axis and the control cabinet. It also supports compact machine designs where distributed drive placement is preferred.

Control electronics operate from a DC 750 V intermediate circuit, eliminating the need for separate low-voltage bus supplies. Axis commands and diagnostics travel over the SERCOS 2 (RS-422) fiber-optic link, allowing deterministic drive networking. All power, brake, feedback, and fieldbus lines terminate on a single Hybrid Connector, simplifying installation in tight spaces. Heat generated by the inverter is removed through natural convection, so no external fans are required. Rotor position is measured by an optical Hiperface encoder that delivers 128 signal periods per revolution, giving fine interpolation for smooth speed loops. The unit uses motor size 076 with length C, winding code 35, and Design Version 2 in the standard design option.

The holding mechanism is an electrically released brake that clamps the shaft when the drive is de-energized and disengages when a control feed of DC 24 V is applied. Because the encoder is single-turn, absolute position data spans one mechanical revolution, which is adequate for indexing tables and pick-and-place arms. A shaft with a keyway transmits torque to couplings while maintaining positive mechanical alignment, and a shaft seal helps prevent lubricant or coolant ingress. The brake supports load retention when power is removed, while the encoder supports normal closed-loop axis control during operation. The unit is Series 1 and is supplied without safety technology, so external motion-safe functions must be handled by the machine controller.
