Product Description:

Bosch Rexroth Indramat builds the KSM02.1B-061C-61N-S3-HP2-ET-L3-D7-NN-FW, a motor-integrated servo drive in the KSM Motor Integrated Servo Drives series. By combining a permanent-magnet motor with embedded power electronics, the unit provides decentralized axis control for conveyors, packaging systems, and material-handling robots. The integrated concept reduces cabinet wiring and positions control intelligence closer to the load, improving response time in distributed automation architectures.

The drive operates from a DC link rated at DC 750 V, allowing it to connect directly to high-power regenerative bus systems without an intermediate inverter. Heat is removed solely through natural convection, so mounting orientation must support unrestricted airflow around the finned housing. A single hybrid connector carries power, EtherNet communication, and safety circuits, simplifying installation on moving axes. For real-time control, the device supports Multi-Ethernet protocols such as EtherNet/IP, EtherCAT, and PROFINET, and it can switch between them through parameter selection. Rotor position is reported over the Hiperface interface, and its capacitive sensor produces 16 signal periods per mechanical revolution, giving sufficient granularity for precise speed loops in compact machines. The encoder is single-turn, so absolute position resets after one rotation.

Machine safety is addressed by hardware-level Safe Torque Off, which removes drive power without affecting fieldbus diagnostics. The electrically released brake engages when the 24-volt supply is absent, and its control circuit is rated at DC 24 V to hold the load during emergency stops. Frame size 061 pairs with motor length C and winding code 61 to suit moderate inertia applications while keeping mass low. The unit has a shaft seal, and the keyed shaft eases torque transfer to pulleys. It uses design version 1, the Standard design option, and Series 2 with a basic performance level.
