Product Description:

The KSM01.2B-061C-61N-S1-HG0-SE-NN-D7-NN-FW is a motor-integrated servo drive from Bosch Rexroth Indramat in the KSM Motor Integrated Servo Drives series. Its housing combines a permanent-magnet servo motor with a compact inverter to provide decentralized axis control in packaging, handling, and assembly equipment. Mounting the drive electronics directly on the motor shortens cable runs, reduces cabinet heat, and allows distributed actuators to share a common DC bus. This layout also helps keep machine wiring compact where several axes are installed across a wide frame.

The drive draws bus power from a DC 750 V supply and routes both energy and feedback lines through a single Hybrid Connector, reducing installation points to one molded plug. Command and diagnostic data move over SERCOS 2, an RS422-based real-time ring used for synchronized multi-axis motion. Heat generated by the inverter is removed by natural convection, so no forced-air or liquid cooling interface is required when the unit is mounted on an open machine frame. Rotor position is measured through a Hiperface interface, allowing the controller to read the absolute angle at startup and carry out closed-loop commutation without an additional homing cycle. This arrangement supports accurate axis response while keeping external connections limited to the motor-mounted unit.

Position feedback comes from an optical single-turn encoder with 128 signal periods per revolution, which suits medium-resolution motion tasks. The motor has a plain shaft with a factory-installed shaft seal that helps separate lubricant from contaminants during operation. The unit is supplied without a holding brake, so vertical loads require an external locking method when power is removed. It is design version 2 with winding code 61, motor size 061, and length C, and it is supplied in the Standard option set with no integrated safety functions. The drive has a Basic performance level for general-purpose servo operation.
