Product Description:

The KSM02.1B-061C-35N-M1-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining the motor, power electronics, and feedback interface into one housing, the unit simplifies cabinet wiring and shortens drive trains in automated machinery. It is intended to regulate position, speed, and torque on distributed axes where compactness and fast installation are priorities in industrial automation cells.

This drive receives its DC link energy through a DC 750 V supply and exchanges process data with the controller over the Multi-Ethernet interface, allowing use with different industrial Ethernet protocols. Power and fieldbus lines are combined in a single Hybrid Connector, so only one cable set reaches the axis. Internal heat is removed by natural convection, so no fan is used and the mounting orientation must support upward airflow. Rotor position is detected by a Hiperface optical encoder that produces 128 signal periods per mechanical turn, giving fine interpolation for smooth velocity loops. The device is supplied without a holding brake, which means any static load must be secured externally if power is lost. Because the design option is Standard and the performance level is Basic, it is intended for general-purpose motion.

The mechanical section corresponds to motor size 061 with length code C, and a plain shaft transmits torque directly to couplings or pulleys. A multi-turn absolute feedback system stores position across 4096 revolutions, eliminating homing after power cycles. There is a shaft seal to limit dust and fluid ingress. The unit comes without safety technology, so any STO or SS1 functions must be provided by upstream hardware. Series number 2, design version 1, and winding code 35 identify the electromagnetic layout used by the drive files.
