Product Description:

The KSM01.2B-071C-35N-M1-HG2-SE-NN-D7-NN-FW is a motor-integrated servo drive built by Bosch Rexroth Indramat and placed within the KSM Motor Integrated Servo Drives series. By combining the motor, power stage, and control electronics in one housing, the unit supports decentralized machine layouts and reduces the amount of separate cabinet hardware and field wiring. It is intended to position or regulate axes on packaging, material-handling, and light machining equipment where compact drive placement helps shorten cable runs and simplify installation.

The drive is energized from a DC 750 V bus, which provides the energy needed for quick acceleration and compact power distribution. Power, signal, and brake conductors reach the unit through a single Hybrid Connector, which keeps the connection layout simple on multi-axis systems. Heat is removed through natural convection, so the unit does not require a fan when it is mounted with adequate free airflow. Rotor position feedback is exchanged with the controller through the Hiperface interface, and this link also supports electronic motor data exchange. Inside the optical encoder, position is subdivided into 128 signal periods, which provides suitable feedback resolution for moderate-precision pick-and-place and feed-axis operation.

The encoder retains position data across power cycles because it uses a multi-turn absolute measuring system, so the axis can return with stored position information after a restart. Load holding is provided by an electrically released brake that operates at DC 24 V, which is useful where the axis must remain fixed when supply power is removed. Communication with the higher-level control takes place through SERCOS 2 (RS422), providing deterministic cyclic data exchange for coordinated motion control. The unit also uses a plain shaft with an integrated shaft seal, and its basic performance level suits standard motion tasks that do not require expanded integrated functions.
