Product Description:

The KSM02.1B-061C-35N-M3-HP2-ET-L3-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. Its housing combines a permanent-magnet motor, power stage, and communication ports, allowing cabinet-free mounting on modular machines. The device delivers closed-loop speed and torque control for packaging axes, compact gantries, and pick-and-place units while reducing wiring and heat inside the control cabinet.

The drive operates from a DC 750 V supply bus generated by a central power module, giving headroom for fast acceleration. Heat is removed through natural convection, so the enclosure must be installed with free air circulation and no extra fans. All power, brake, and feedback conductors share a single Hybrid Connector, which combines these connections in one interface and minimizes cable runs on moving carriages. Rotor position is measured with a capacitive encoder that provides 16 signal periods per mechanical revolution, and this resolution supports smooth velocity loops at low speed. Network traffic is handled by its Multi-Ethernet interface, allowing connection to EtherNet/IP, PROFINET, or EtherCAT networks.

Functional safety relies on Safe Torque Off (STO) channels that cut gate signals inside the inverter, removing motor torque without disabling the DC link. An electrically released brake energized at DC 24 V keeps the shaft locked during power loss or an emergency stop. The Hiperface encoder interface transmits absolute multi-turn data, preserving position after shutdown and enabling homing-free restarts. A shaft with a keyway secures mechanical coupling, and the built-in shaft seal helps block splash and dust near the bearing area. Length C, size 061, and winding code 35 place the unit in the basic performance tier for moderate inertia loads.
