YOKOGAWA F3NC01-0N
1. Basic Information
YOKOGAWA F3NC01-0N is a high-performance network motion positioning module for the YOKOGAWA FA-M3 PLC system. It acts as a MECHATROLINK-III fieldbus master station, dedicated for high-precision multi-axis servo and stepper motion control. It supports point-to-point positioning, multi-axis interpolation, synchronous motion and closed-loop trajectory control.
Adopting industrial Ethernet-based cyclic communication architecture, the module eliminates the defects of traditional pulse control such as complicated wiring and anti-interference weakness. With independent motion logic operation and full fault diagnosis functions, it ensures stable, high-precision and synchronous operation of automated motion equipment, and is widely used in equipment upgrading and spare part replacement of FA-M3 series systems.
