KSM01.2B-076C-35N-S1-HG2-SE-NN-D7-NN-FW by Bosch Rexroth Indramat

The KSM01.2B-076C-35N-S1-HG2-SE-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat and belongs to the KSM Motor Integrated Servo Drives series. As a motor-integrated servo drive, it combines a servo motor, drive electronics, and a fieldbus interface in one unit, allowing motion axes to be mounted directly on the machine frame without a separate cabinet-mounted drive. This integrated arrangement reduces wiring between the motor and control cabinet while supporting distributed automation architectures in packaging, material-handling, and assembly systems. The compact configuration also reduces the number of separately mounted components required for each controlled axis.

The drive is powered by a bus voltage of DC 750 V, allowing connection to a common DC link in multi-axis installations. Power, signal, and safety conductors share a single hybrid connector, reducing the number of separate connections and simplifying cable routing. Heat generated by the electronics is dissipated through natural convection, so the unit does not require an active cooling fan. Rotor position is measured by an optical encoder with a Hiperface interface, providing digital feedback that is compatible with supported Rexroth controllers. The encoder supplies 128 signal periods per mechanical revolution, providing the feedback resolution needed for closed-loop speed and position control.

The electrically released holding brake clamps the shaft when control power is removed and releases it when the brake coil is energized. Its coil operates with DC 24 V, matching the auxiliary control voltage commonly available in industrial machines. Network communication uses SERCOS 2 over RS-422, which supports deterministic data exchange with higher-level motion controllers. The motor has a frame size of 076 and a length code of C, providing the mechanical envelope associated with this model. Its plain shaft includes an installed shaft seal that helps prevent contaminants from reaching the bearing area. The motor uses winding code 35 and has a standard design configuration for applications that use external machine-level safety circuitry.
