Product Description:

The KSM01.2B-061C-35N-M1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. It combines the servo motor and drive electronics in one housing, which reduces cabinet wiring and supports distributed machine layouts with shorter internal feedback paths. The unit is intended for positioning and speed control on small-to-medium axes, including transfer units, indexing devices, and compact handling systems. Direct mounting on the machine frame also keeps the installation close to the load and reduces the amount of external cabling required between the axis and the control cabinet.

Power enters through a Hybrid Connector that carries the DC bus, logic supply, and communication in one connection. The internal power stage operates from DC 750 V, and heat is removed by natural convection, so the housing does not require a fan or liquid cooling circuit. Rotor position feedback is provided through Hiperface, and the optical system delivers 128 signal periods per revolution. It also supports multi-turn absolute position retention, which allows the controller to recover the shaft position after power loss without requiring a reference move at every startup.

Torque is transmitted through a plain shaft, and a shaft seal is fitted to help limit contaminant entry at the output end. Command communication uses SERCOS 2 (RS-422), allowing cyclic data exchange with compatible Rexroth control systems during synchronized motion. The motor section uses size 061 with length C and winding code 35, matching the compact electromagnetic stack used for this frame. The unit has a basic performance level, design version 2, and series index 1. It is supplied without a holding brake, so any load that must remain fixed at standstill needs external holding force or drive-applied torque.
