Product Description:

The KSM02.1B-061C-61N-S1-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. This device merges a synchronous servomotor and a drive controller inside one housing, enabling decentralized installation on the machine frame. In industrial automation, such compact units simplify wiring, reduce cabinet heat, and provide closed-loop axis control for packaging, material handling, and assembly stations that run from a shared DC bus.

It operates from a shared DC link of DC 750 V, letting multiple axes draw power without individual converters. Control and power conductors merge in a Hybrid Connector, so only one cable is routed to the cabinet. Internal heat leaves the housing through natural convection, making the unit suitable for mobile or articulated axes where fans or coolant loops are impractical. Position feedback is supplied by a Hiperface optical encoder that generates 128 signal periods per revolution and supports single-turn absolute referencing. Command data pass through Multi-Ethernet, allowing SERCOS III, EtherNet/IP, PROFINET IO, or EtherCAT to be selected in software. An electrically released brake engages when control power is removed and is energized with DC 24 V to hold vertical loads during idle or emergency stop.

The unit uses the 061 frame, which provides the torque class required for mid-range pick-and-place axes while remaining light enough for robot wrists. The drive belongs to the Basic performance level, so its standard design, version 1 electronics, winding code 61, motor length C, and hardware series 2 meet moderate dynamic demands rather than high-end servo loops. Output torque is delivered through a shaft with a keyway, and a shaft seal prevents contaminants from reaching the feedback cavity. The unit is supplied without safety technology, so any STO or SS1 functions must be implemented in the external controller.
