1.2.2 Main Unit (Transistor Output)
The FX3G/FX3U/FX3UC PLC incorporates positioning functionality.
The PLC can output an open collector type pulse train of up to 100 kHz from the general-purpose outputs
(Y000 to Y002), and it can simultaneously control 3 axes
*1
.
*1. 14-point and 24-point type FX
3G PLC can only control 2 axes.
1.2.3 Special Adapter
The special adapter can output differential line driver type pulse trains of up to 200 kHz using the positioning
functionality incorporated in the FX
3U PLC, and can simultaneously control up to 4 axes.
Up to 2 high-speed output special adapters (FX
3U-2HSY-ADP) can be connected to the FX3U PLC.
• The first FX
3U-2HSY-ADP uses Y000 and Y004, and Y001 and Y005.
• The second FX
3U-2HSY-ADP uses Y002 and Y006, and Y003 and Y007.
