1.2 Introduction of Products Needed for Positioning

FX /FX /FX /FX /FX PLC User's Manual - Positioning Control Edition Common Items

1.2.3 Special Adapter (Differential Line Driver Output)

The special adapter can output pulse trains of up to 200 kHz using the positioning functionality incorporated in the FX3U PLC, and can simultaneously control up to 4 axes.

Up to 2 high-speed output special adapters (FX3U-2HSY-ADP) can be connected to the FX3U PLC.

• The first FX3U-2HSY-ADP uses Y000 and Y004, and Y001 and Y005.

• The second FX3U-2HSY-ADP uses Y002 and Y006, and Y003 and Y007.

Cautions when connecting special adapters

• To use high-speed output special adapters only (not to use the other special adapters), it is not necessary to connect the expansion board.

• To use the analog, communication, and CF card special adapters, be sure to connect the expansion board.

• To use high-speed output special adapters together with the analog, communication, and/or CF card special adapters, connect the high-speed output special adapters to the expansion board (already connected to the FX3U PLC) first, and then connect the analog special adapters, communication, and/or CF card special adapter(s).
