Product Description:

The KSM02.1B-076C-35N-M3-HG0-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat within the KSM Motor Integrated Servo Drives series. By combining control electronics and a synchronous motor in one housing, the unit provides decentralized axis control for machines that need compact installation in industrial automation environments. It belongs to generation 2 of the platform and is intended to position or regulate rotary motion directly on the machine frame, which helps reduce cabinet space and cable runs.

The drive accepts a DC 750 V bus supply through a single Hybrid Connector, so power and SERCOS/Ethernet communication reach the device through one shielded cord set. Heat is removed by natural convection, eliminating the need for fans and allowing installation in sealed zones. The unit uses size 076 with motor length C, and winding code 35 matches the basic performance level of this design. Real-time axis commands arrive over the Multi-Ethernet master interface, and the output coupling allows the network to daisy-chain to the next module. Actuator feedback is reported through a Hiperface encoder that provides 16 signal periods per electrical revolution, enabling precise commutation without additional external sensors.

The feedback element uses capacitive scanning to resist dust and vibration, and its Multi-turn absolute capability preserves position data across power cycles. The motor has a plain shaft with an integral shaft seal that helps prevent lubricant escape and blocks contaminants. The assembly is supplied without a holding brake, so static load retention must rely on drive torque or an external clamping device. Functional safety is handled by Safe Torque Off (STO) channels that interrupt power to the motor windings when a monitored fault occurs.
