Working Principle
The S20660-CNS converts AC input power to a regulated DC bus and uses high-bandwidth digital control loops (5 kHz current, 800 Hz velocity) to precisely regulate motor torque and speed. The CANopen interface receives motion commands from a master controller over the fieldbus, executing CiA 402 drive profile commands for position, velocity, and torque modes. The intelligent feedback device provides automatic motor identification and tuning, enabling rapid commissioning.
