Product Description:

The KSM02.1B-061C-35N-S3-HG0-ET-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. It merges drive electronics and a synchronous motor of size 061 and length C inside one housing, enabling decentralized mounting directly on machine frames. This arrangement places the motor and inverter in one compact assembly, which helps shorten cable runs on distributed axes. This combination suits compact machine sections where motion hardware is mounted close to the driven mechanism rather than in a central cabinet. In automated production, the unit supplies closed-loop torque, speed, and position control while minimizing cabinet wiring for multi-axis systems.

Power enters the unit through a hybrid connector that carries DC bus, logic supply, feedback, and network lines in a single lead, simplifying cable routing between the cabinet and the drive. Thermal energy is removed only by natural convection, so no fan or liquid circuit is required when ambient air can circulate around the housing. The power stage operates from a DC 750 V link and is matched to winding code 35, supporting the torque capability required by the machine axis. Position data are returned through a Hiperface interface, and the feedback device is a single-turn scanner, so absolute position is retained within one mechanical revolution. The model is delivered in the standard design option with design version 1 and a basic performance level, and it belongs to Series 2. The unit has no holding brake, and a shaft seal limits ingress around the rotating journal.

A capacitive encoder yields 16 signal periods per turn, and this resolution supports smooth velocity loops without adding mechanical fragility. Integrated support for Multi-Ethernet motion protocols lets the axis register on EtherCAT, PROFINET, or SERCOS networks through the same port. This network flexibility allows the same drive platform to fit several control architectures without changing the motor-integrated layout. Output torque is transmitted through a plain shaft, which simplifies coupling to rigid hubs and backlash-free gear stages. Because no integrated safety technology is provided, external modules must implement safe torque off or emergency stop functions when the machine standard requires them.
