Product Description:

The KSM02.1B-061C-35N-S1-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. It combines a permanent-magnet servo motor and a drive controller in one housing, so motion axes can be mounted without separate cabinet hardware. The unit is Series 2 with the basic performance level, Design Version 1, and the standard design option. In automated equipment, it provides closed-loop positioning, speed control, and torque regulation for packaging, material handling, and assembly stations. This layout reduces the distance between the power stage and the motor windings, which supports responsive axis control on compact machines.

The servo drive accepts power from a DC 750 V shared bus and routes signals through a single Hybrid Connector that combines power, feedback, and communication lines. Internal heat is removed by natural convection, eliminating the need for fans or liquid circuits. Position feedback is generated by a Hiperface optical encoder that provides 128 signal periods per mechanical revolution, and the transducer operates as a single-turn device for absolute position within one turn. The motor section has size 061 with length code C, and its three-phase stator uses winding code 35 for the intended torque constant. A shaft seal helps protect the bearings from contaminants.

Machine safety functions are handled externally because the unit is supplied without integrated safety technology, while motion holding is provided by an electrically released brake powered at 24 V DC. Drive commands travel through the Multi-Ethernet network layer, so control systems can use PROFINET, EtherNet/IP, or EtherCAT without hardware changes. The encoder’s optical scanning principle resists electrical noise, and torque is transmitted through a shaft with a keyway that matches standard couplings. The integrated format also shortens cabling between the motor and drive electronics inside the axis assembly. Integrated control and thermal management support compact installation where cabinet space is limited.
