1. Outline
FX3U-4HSX-ADP high-speed input special adapter (hereinafter called high-speed input
special adapter) is a special adapter dedicated to FX3U Series PLC. It retrieves pulse
signals from a rotary encoder of which the output type is a differential line driver to a
high-speed counter or SPD instruction (FNC 56).
Up to two units of this high-speed special adapter can be connected to the main unit
per system.
→ For system configuration, refer to the FX3U Series
User's Manual - Hardware Edition.
1.1 Incorporated Items
Check if the following product and items are included in the package:
1.2 Input Allocation and Usable High-Speed Counter Number
When the power is turned on, input numbers of the high-speed input special adapters
are allocated as shown in the table below in the order of unit position to the main unit.
See the table below for usable device number of associated high-speed counter.
→ For details of high-speed counters, refer to the FX3U Series
User's Manual - Hardware Edition.
*1 A function extension board is required to use the high-speed I/O special adapter
together with a communication/analog special adapter.
→ For system configuration, refer to the FX3U Series
User's Manual - Hardware Edition.
*2 Use the terminal of the main unit for reset input if the second high-speed input
special adapter is not connected.
*3 Use the terminal of the main unit for start input and reset input if the second high-
speed input special adapter is not connected.
Caution
When connecting a high-speed input special adapter, same input numbers are
allocated to the main unit and this special adapter. Must use either one of the
input terminals. If both input terminals are used, assumed action may not be
executed because inputs of the high-speed input special adapter and main unit
are operated in an OR relationship to each other.
• Do not use (wire) the input terminal in main unit corresponding to the input
number used in the high-speed input special adapter.
• Do not use (wire) the input terminal in high-speed input special adapter
corresponding to the input number used in the main unit.

3. Used cables and Tightening Torque on Terminal
For connection example and wiring, refer to the following manual.
→ Refer to FX3U Series User's Manual - Hardware Edition.

1)Wire size
To connect to the desired unit, use a shielded twisted pair cable having a
conductor(s) of size AWG22-20.
2) Applicable cable
3) Termination of cable end
Strip the coating of strand wire and twist the cable core before connecting it,
or strip the coating of single wire before connecting it.
An alternative connection is to use a ferrule with insulating sleeve.
When using a stick terminal with insulating sleeve, choose a wire with proper
cable sheath referring to the above outside dimensions, or otherwise, the wire
cannot be inserted easily.
The tightening torque must be 0.22 to 0.25N•m.
WIRING
PRECAUTIONS
• Cut off all phases of power source externally, before installation or wiring
work in order to avoid electric shock or damage of product.
WIRING
PRECAUTIONS
• Never let cutting chips and wire chips enter the ventilation slits of this product
or PLC when performing wiring.
Otherwise, fire, failure or malfunction may occur.
• Make sure to observe the precautions below in order to prevent any damage
to a machine or any accident which might be caused by abnormal data
written in the PLC due to the influence of noise:
1) Do not lay close or bundle with the main circuit, high-voltage power line,
or load line.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm (3.94") from the above when
wiring.
2) Ground the shield wire or shield of a shielded cable at one point on the
PLC. However, do not ground at the same point as high voltage lines.
• Observe the following items to wire the lines to the European terminal board.
Failing to do so may cause electric shock, short circuit, disconnection, or
damage of the product.
- The disposal size of the cable end should follow the dimensions described
in this manual.
- Tighten to a torque should follow the torque described in this manual.
- Twist the end of strands and make sure there is no loose wires.
- Do not solder-plate the electric wire ends.
- Connect only the electric wires of regulation size.
- Fix the electric wires so that the terminal block and connected parts of
electric wires are not directly stressed.
