Product Description:

The KSM02.1B-061C-61N-M3-HP0-ET-L3-D7-TO-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat as part of the KSM Motor Integrated Servo Drives series. By combining drive electronics and a permanent-magnet synchronous motor within one housing, the unit provides decentralized axis control for conveyors, handling modules, and packaging stations in industrial automation. This layout places the power electronics directly at the axis, which helps simplify distributed machine designs and reduces the need for separate drive cabinets near the motor. Functional safety is implemented through Safe Torque Off (STO), which removes energy from the stator windings without additional contactors.

The drive is supplied from a common DC bus at DC 750 V, which lets multiple axes share regeneration energy without separate rectifiers. The common bus arrangement also allows energy exchange between accelerating and decelerating axes during coordinated motion. Power, encoder, and fieldbus lines are routed through a single Hybrid Connector, so installation uses one pluggable interface. Thermal management relies on natural convection; the aluminum housing transfers heat to ambient air and eliminates serviceable fans. Rotor position is reported over the Hiperface serial channel, and the internal measurement system outputs 16 signal periods per mechanical revolution and uses a capacitive scanning principle to maintain accuracy in high-vibration or magnetic environments. This combination belongs to design version 1, winding code 61, and motor length C, giving the electrical characteristics expected for the 2-series platform.

Motion feedback remains available after power cycling because the encoder is a multi-turn absolute device with electronic revolution counting. Mechanical coupling is handled by a shaft with a keyway, and a shaft seal is fitted to resist dust and spray around the 061 frame motor. The unit ships without a holding brake, so external measures are required to secure vertical loads. A Multi-Ethernet interface and the matching master protocol enable cyclic data exchange over EtherCAT, PROFINET, SERCOS III, or EtherNet/IP. This communication arrangement lets the same drive architecture fit control systems built around different industrial Ethernet networks.
