Product Description:

The KSM02.1B-076C-35N-M3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet servo motor, power stage, and feedback electronics in one housing, it provides decentralized axis control for conveyors, pick-and-place gantries, and other compact automation equipment. This integrated layout reduces cabinet space requirements and helps limit wiring complexity on machines with distributed motion axes.

The drive operates from a shared bus rated at DC 750 V, allowing long DC links without step-down transformers. Power, signal, and safety conductors are bundled in a single hybrid connector that simplifies installation and limits cable runs on moving axes. Thermal energy is dissipated by natural convection, so ambient airflow around the housing must remain unobstructed. Position data is transferred through a Hiperface interface, and the internal capacitive encoder provides 16 signal periods of multi-turn absolute feedback to the controller. An electrically released holding brake, energized with 24 V DC, locks the rotor whenever system power or an emergency stop removes the control voltage.

The communication layer is based on Multi-Ethernet, allowing operation over EtherNet/IP, PROFINET, or EtherCAT without changing hardware. Functional safety is provided by Safe Torque Off (STO), which disables the drive power stage through internal circuitry. For mechanical coupling, the motor uses a shaft with a keyway, and a shaft seal helps prevent lubricant leakage into the motor cavity. The compact C length within the 076 frame code balances moment of inertia with torque density, while winding code 35 suits the basic performance profile for moderate duty cycles. The unit is design version 1 in a standard configuration and is part of series 2.
