Product Description:

The KSM01.2B-061C-61N-S1-HP0-SE-NN-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining power electronics, feedback circuitry, and a permanent-magnet servo motor in one housing, it supports decentralized motion control on moving machine axes and reduces cabinet wiring. Mounting the drive directly at the axis shortens motor cable runs and keeps the control hardware close to the load. The integrated format also suits machine sections where the drive moves with the axis instead of remaining in a central cabinet. This arrangement is used in packaging, material-handling, and assembly systems that require closed-loop speed and position control in a compact footprint.

The unit operates from a supply link of DC 750 V, so it can share a common DC bus with other axes and regenerative modules in the same system. Power, signal, and safety conductors are routed through a single Hybrid Connector, which reduces the number of separate connections on the machine and keeps cable routing compact. Heat produced by the embedded inverter is removed through natural convection, so no fans are required. Rotor position feedback is supplied by a Hiperface encoder with 128 signal periods per revolution, allowing fine interpolation for smooth motion at low and moderate speeds. The optical sensing method avoids the mechanical wear associated with resolver-based systems and supports repeatable positioning during frequent start-stop cycles.

Real-time axis commands reach the drive over the SERCOS 2 (RS422) bus, keeping position updates synchronized with other drives on the network during coordinated motion. Output torque is transmitted through a shaft with a keyway, and a shaft-end seal helps block coolant or dust at the front bearing. Electromagnetic parameters tied to winding code 61 set the continuous current limits for the basic performance level. The unit is design version 2, and the single-turn feedback structure supports straightforward homing after startup. It is supplied without a holding brake.
