KSM02.1B-061C-61N-M1-HG2-ET-L3-D7-NN-FW by Bosch Rexroth Indramat

The KSM02.1B-061C-61N-M1-HG2-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. By combining drive electronics, feedback, and a 061-frame permanent-magnet motor in a single housing, it streamlines installation on distributed machine axes located far from control cabinets. The unit delivers closed-loop positioning and speed control for packaging stations, pick-and-place robots, and conveyor gantries. Its integrated design reduces the amount of equipment and wiring required around each controlled axis.

The drive connects to a bus rated at 750 V DC, allowing it to share a common supply with other regenerative axes on the machine. Power, brake conductors, and fieldbus signals are routed through a hybrid connector, eliminating the need for separate feedback and I/O cables. Heat is removed by natural convection, and the absence of cooling fans simplifies maintenance in environments containing airborne particles. Position feedback is generated by a Hiperface optical encoder that provides absolute multi-turn position data. Interpolation provides 128 signal periods per mechanical revolution, supporting fine motion profiles during synchronized operation. The encoder operates with winding code 61 and motor length C to match the torque and inertia requirements of basic-performance applications.

Network integration is handled by Multi-Ethernet hardware that can be configured for EtherNet/IP, PROFINET, or EtherCAT without additional option cards. Functional safety is provided through Safe Torque Off (STO), which removes torque-producing power while allowing fieldbus communication to remain active. Vertical loads are held by an electrically released brake that clamps when control power is lost. The brake coil operates from 24 V DC. A plain shaft with a factory-installed seal helps prevent lubricant migration and protects the motor interface from contamination. The standard mechanical design is version 1 and supports KSM mounting flanges used with series 2 products.
