Product Description:

The KSM02.1B-061C-61N-M1-HG2-ET-L3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By embedding the power stage and control electronics into a 061-frame permanent-magnet motor, it delivers decentralized speed and position regulation directly on the machine. This arrangement removes cabinet inverters, shortens cable runs, and supports distributed motion on packaging, assembly, and material-handling equipment. Mounting the drive near the load also helps reduce installation complexity where several axes are spread across a machine frame. It suits machine sections where local drive placement reduces the number of long motor leads.

Power reaches the unit through a single-cable interface that terminates in a Hybrid Connector. The internal inverter is fed from a DC 750 V bus and releases heat through natural convection, so no fans or liquid lines are needed. Inside the C-length housing, winding code 61 pairs with motor size 061 for the basic performance level in Series 2, and Design Version 1 identifies the current layout. Position feedback is generated by a Hiperface optical encoder that resolves 128 signal periods per revolution and stores multi-turn absolute data. This feedback arrangement supports closed-loop commutation and makes the rotor position available without a separate external feedback device. A factory-installed shaft seal helps protect the internal bearings from dust and fluids.

Network traffic and downstream axis chaining are handled through Multi-Ethernet. This communication method supports real-time data exchange between the axis and the higher-level control system while simplifying connections to neighboring units. Functional safety is addressed by the integrated Safe Torque Off (STO) circuit, which disables drive output without removing DC link power. Load holding on vertical axes is provided by an electrically released brake energized at DC 24 V, and torque is removed automatically when control voltage is lost. Mechanical power exits through a plain shaft, allowing straightforward attachment of pulleys, pinions, or gearheads.
