-4HSX-ADP high-speed input special adapter (hereinafter called high-speed input

special adapter) is a special adapter dedicated to FX

3U

 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 details on system configuration, refer to the following manual.

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.

Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.

INSTALLATION 
PRECAUTIONS

Use the product within the generic environment specifications described in
PLC main unit manual (Hardware Edition).

dusts, corrosive gas (salt air, Cl

2

, H

2

S, SO

2

 or NO

2

), flammable gas, vibration

or impacts, or expose it to high temperature, condensation, or rain and wind.
If the product is used in such conditions, electric shock, fire, malfunctions,
deterioration or damage may occur.

 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. 

*1 Old model name: CRIMPFOX ZA 3
*2 Old model name: CRIMPFOX UD 6

When using a ferrule with insulation 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. Do not tighten terminal screws

with a torque outside the above-mentioned range.
Failure to do so may cause equipment failures or malfunctions.

WIRING 
PRECAUTIONS

Make sure to cut off all phases of the power supply externally before
attempting installation or wiring work.
Failure to do so may cause electric shock or damage to the product.

WIRING 
PRECAUTIONS

When wiring, make sure cutting or wire debris does not enter the ventilation
slits.
Failure to do so may cause fire, equipment failures or malfunctions.

Make sure to observe the following precautions in order to prevent any
damage to the machinery or accidents due to abnormal data written to the
PLC under the influence of noise:

1) Do not bundle the main circuit line together with or lay it close to the main

circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take
place. As a guideline, lay the control line at least 100mm (3.94") or more
away from the main circuit or high-voltage lines.

2) Ground the shield wire or shield of the shielded cable at one point on the

PLC. 
However, do not use common grounding with heavy electrical systems.

Make sure to properly wire to the European terminal board in accordance
with the following precautions.
Failure to do so may cause electric shock, equipment failures, a short-circuit,
wire breakage, malfunctions, or damage to the product.

- The disposal size of the cable end should follow the dimensions 

described in the manual.

- Tightening torque should follow the specifications in the manual.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires 

of unspecified size.

- Affix the electric wires so that neither the terminal block nor the connected 

parts are directly stressed.
