KSM02.1B-061C-61N-M1-HG2-ET-S3-D7-TO-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG2-ET-S3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By embedding the drive electronics directly on the motor frame, the unit reduces cabinet space and localizes motion control at the axis. It is used in industrial automation to position tooling or transport mechanisms where a decentralized architecture shortens cable runs and simplifies machine layouts.

Power for the drive stage is supplied from a direct-current bus at DC 750 V, so the device connects to common multi-axis DC-link systems without an internal rectifier. Thermal losses are removed through natural convection, eliminating the need for forced-air fans and allowing sealed mounting in exposed machine areas. All power, logic, and brake conductors enter through a hybrid connector, reducing the connector count and simplifying installation. An electrically released holding brake clamps the shaft whenever the 24 V control line is de-energized. Its release voltage is supplied by a separate circuit rated at DC 24 V. The motor has frame size 061 and frame length C, providing a continuous torque class suitable for light- to medium-duty process axes.

The integrated feedback system uses a Hiperface interface to carry incremental and absolute position data to the controller. Position granularity is provided by 128 signal periods per mechanical revolution. A multi-turn absolute encoder tracks complete revolutions, eliminating the need for homing after power loss. Functional safety is implemented through Safe Motion without SBC, allowing hardware-based monitoring of velocity limits and standstill conditions. Multi-Ethernet communication supports data exchange with the machine controller, while the Basic performance level identifies the drive's functional configuration. The motor has a plain shaft with a shaft seal, and winding code 61 identifies its electrical winding arrangement. These features support precise motion in packaging, material-handling, and assembly applications without requiring additional electrical panel space.
