Positioning ; FX3S,FX3G,FX3U,FX3UC

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. With high performance a low cost, the FX Series positioning possibilities provide a formidable package.

Upgraded Built-in Positioning

Instructions for Easier Use

The FX Series allows for up to 3 axes of independent positioning control at up to 100 kHz.

Connecting two high-speed output special adapters to the FX3U allows for up to 4 axes of control at up to 200 kHz.

Easy Step-By-Step Positioning

Programming Using the DTBL Instruction.

High -Speed, High-Precision
Positioning Solution

For advanced positioning applications, the FX3U and FX3U controllers can be expanded with the FX3U-220SSC-H special function block. With SSCNET, 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.

Plug-and-Play fiber optic cable connectivity to servo equipment eliminates wiring errors and enhances data transfer reliability and noise resistance while supporting node-to-node distances of up to 50 m. At 50 Mbps transmission speed with highly reduced communication cycle times as low as 1.77 ms, the FX3U-20SSC-H and create a high-powered solution for a variety of applications.

Changing the Speed and Target Address

Speed change Function
The operation speed can changed arbitrarily during operation.

2-Axis 50 Mbps Network Control

Unparalleled communication speed through SSCNET

Interpolated Positioning 
2-Axis Linear Interpolation
2-Axis Circular Interpolation

Simultaneous Start Function
Both the X and Y axes can be controlled with a timed start,
allowing for synchronous positioning operations

Inching Operation 
if the forward /reverseJOG activation time is within the JOG determination time, a pulse string equivalent to +1 (user unit) is output at the current address.

Speed Override Function
The operation speed
ratio can be changed
arbitrarily during operation

Target Address Changed Function
The target address can be changed to a new address arbitrarily during operation
