Product Description:

The KSM02.1B-061C-61N-M1-HG2-ET-L3-D7-NN-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. Combining inverter electronics and a synchronous motor in one housing lets the device mount directly on machinery and reduces cabinet wiring. It provides distributed torque and velocity control for packaging lines, pick-and-place axes, and other automated stations where compact motion modules are preferred.

This unit accepts a bus supply of DC 750 V and dissipates heat through natural convection, eliminating forced-air components in tight spaces. All power, feedback, and network lines are routed through a single Hybrid Connector, and drive-to-controller data exchange is handled by Multi-Ethernet interfaces that support several real-time fieldbus variants. A functional safety channel implemented as Safe Torque Off (STO) permits immediate prevention of unintended motion without removing the main supply. The drive uses motor size 061 with length C, has the basic performance level, and is in Series 2 with design version 1.

Position feedback is delivered through a Hiperface interface that carries data from an optical, multi-turn absolute encoder with 128 signal periods per revolution, enabling precise commutation and absolute position recovery after power cycles. For load-holding tasks, an electrically released brake engages when the DC 24 V control line is de-energized. The output uses a plain shaft, which simplifies coupling to belt pulleys or direct-drive elements without keyways. A shaft seal limits ingress, and winding code 61 matches the electrical characteristics of the integrated power stage.
