KSM02.1B-061C-61N-M3-HP2-ET-NN-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M3-HP2-ET-NN-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines power electronics, control logic, and a synchronous motor in one enclosure, simplifying the installation of decentralized axes in industrial automation. The integrated design supplies precise torque and position control for conveyors, pick-and-place arms, and similar motion tasks while minimizing external wiring between the motor and drive.

Incoming DC power at 750 V feeds the drive stage and is modulated for the three-phase stator windings. The motor has winding code 61, frame size 061, and frame length C. Heat is removed through natural convection, so external fans are unnecessary when the permitted ambient limits are observed. A Hiperface interface connects the control electronics to a feedback sensor that provides 16 signal periods per mechanical revolution. Its capacitive design is resistant to interference from magnetic debris. Multi-turn absolute feedback retains position data after power cycles, allowing operation to resume without a new homing procedure. Axis clamping after power is removed is handled by an electrically released brake supplied with 24 V DC. Mechanical energy is transmitted through a shaft with a keyway, providing positive engagement with pulleys or rigid couplings.

For field wiring, the motor-integrated design provides a hybrid connector that carries DC power, feedback, and brake conductors through a single keyed plug. Motion commands and diagnostic data are exchanged over Multi-Ethernet. A matching output port allows additional axes to be connected in a daisy chain. The unit operates at the Basic performance level, which is suitable for moderate-duty positioning lines. A shaft seal limits the entry of contaminants along the rotating interface. The product is design version 1 and belongs to series 2.
