The built-in high-speed pulse outputs on all transistor-type FX Series PLCs, along with special positioning operations instructions, are designed to satisfy simple independent-axis positioning applications using servo and stepping motors with speed and precision. For more advanced applications like 4-axis control and noise-free interpolation, the FX system can be expanded with special adapters and special function blocks.

Built-in positioning - Simple Solution
The FX3U/FX3UC/FX3G allow for 3 axes of independent positioning control at up to 100kHz. Connecting two high-speed output special adapters to the FX3U allows for up to 4 axes of control at up to 200kHz.*

SSCNET - Advanced Solution
For advanced positioning applications, the FX3U and FX3UC controllers can be expanded with the FX3U-20SSC-H special function block. With SSCNET III, smooth, high-speed, high- precision operations become easy to setup and execute. Use the FX PLC to set positioning and servo parameters, while monitoring the absolute axis position for program interaction.
