Product Description:

The KSM02.1B-061C-35N-M1-HP2-ET-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. The unit combines a size 061 synchronous motor with length code C and an onboard inverter, creating a decentralized axis that mounts directly on the machine frame. Classified as design version 1 with the standard mechanical option and a basic performance level, it is intended for medium-duty positioning tasks. Series 2 allows the device to accept a shared DC bus, and a shaft seal guards the front bearing against dust and coolant splash.

For electrical integration, a hybrid connector carries power, fieldbus, and I/O on a single molded plug, which reduces cable runs to the drive. The power stage operates from a DC 750 V supply drawn from the machine's common bus, and heat is removed by natural convection, so no fans or liquid circuits are required. Motion commands arrive through Multi-Ethernet communications that support several real-time Ethernet dialects without additional option cards. Position feedback reaches the controller through a Hiperface optical encoder that generates 128 signal periods per revolution, and the encoder stores multi-turn absolute data so homing routines are unnecessary after power cycles.

Mechanical holding force is handled by an electrically released brake that engages automatically when control power is lost, and its coil is energized with DC 24 V supplied through auxiliary pins of the single power and communication connector. Torque is transmitted through a shaft with a keyway, which matches standard couplings, while winding code 35 sets torque and current values appropriate to the basic performance class. The unit contains no integrated safety technology, so external solutions must supervise motion.
