Product Description:

The KSM01.2B-061C-35N-S1-HP2-SE-NN-D7-NN-FW is manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining a brushless servo motor, inverter, and feedback electronics in one housing, it works as a compact axis controller that mounts directly on machinery. This arrangement supports packaging, assembly, and handling equipment that need accurate position and speed control while reducing cabinet space and external wiring. Mounting the drive electronics at the axis can also shorten cable routing and help keep decentralized machine layouts more compact. Because the motor and drive are housed together, fewer separate components are needed on the machine frame.

Electrical power reaches the unit through a Hybrid Connector that combines DC-link, logic, and communication conductors in one plug. The internal power stage operates from a nominal bus of DC 750 V supplied by an external source, and it is matched to winding code 35. Heat is removed by natural convection, so no fan or liquid circuit is required when surrounding airflow is sufficient. Position feedback is transmitted through a Hiperface interface, and the optical encoder provides 128 signal periods per revolution for closed-loop motion control. Using one connector for several circuits also reduces the number of separate cable interfaces at the housing.

The motor section uses size 061 with length code C, giving a compact frame for distributed servo duties. The output shaft has a keyway and an integrated shaft seal, allowing direct coupling in dusty areas. An electrically released brake, energized at DC 24 V, holds the axis when power is removed. Command and diagnostic signals are communicated over SERCOS 2 (RS422) for deterministic data exchange with the higher-level control. The unit has a standard design and a basic performance level. It is built as series 1 with version 2 hardware, and external circuitry must handle emergency-stop functions.
