Product Description:
The KSM02.1B-061C-61N-M1-HG0-ET-S3-D7-TO-FW is a motor-integrated servo drive manufactured by Bosch Rexroth Indramat for the decentralized KSM Motor Integrated Servo Drives series. By combining power electronics, control functions, and the servo motor in one housing, the unit reduces cabinet wiring and mounts directly on the machine frame. A hybrid connector carries DC-bus power and communication lines through a single cord set, which helps simplify installation. The unit is design version 1 and belongs to series 2 in the product family, supplying precise torque control for conveyor, packaging, and assembly axes.
The drive section is energized from a stabilized bus of DC 750 V, allowing several axes to share a common supply and regenerative energy. Heat generated by the inverter is removed through natural convection, and no fans are installed. Position feedback is provided through the Hiperface interface, which carries absolute data from an optical multi-turn encoder in real time. The encoder produces 128 signal periods per mechanical revolution, giving fine angular resolution for smooth speed loops. For machinery that locks loads mechanically, the motor is supplied without a holding brake to reduce mass and inertia.
Motion commands and diagnostic data travel through the unit’s integrated Multi-Ethernet interface, permitting selection among PROFINET, EtherNet/IP, or EtherCAT without changing the unit. Functional safety is handled onboard by the Safe Motion option, enabling speed and position monitoring up to SIL2/PL d without an internal safe brake controller. The motor has motor size 061 with a compact C-length stator, a plain shaft, and a shaft seal that helps block lubricant escape. Electromagnetic behavior is set by Winding Code 61, which matches the torque-speed curve to the basic performance level used for secondary process axes.
