WIRING
PRECAUTIONS
• 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 terminal board (European type) 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.

exceeding the specified torque. Failure to do so may cause equipment failures or
malfunctions.
Tool
To tighten terminals, use a purchased
small-sized screwdriver whose head is

1. Outline
The hardware high-speed counter block is a 2-phase 50 kHz high-speed counter. It is a
special function block for the FX , FX series PLC.
2NC 3UC
• FROM/TO instruction transfers the PLC data (i.e. parameters, comparing value and
present value).
• The FX occupies 8 points of I/O on the FX
2NC-1HC
8 points can be allocated from either inputs or outputs.
However, 5V DC 90mA power is supplied from the main unit or extension power
supply units. There must be no power overload from this or any other extension unit.
Furthermore, another power supply is needed for the output circuit of the encoder or
the transistor.
• Differential-Line-Driver (AM26C31 or equivalent) and open collector output
encoders are available for FX -1HC.
2NC
• The source of your input signal should be a 1 or 2 phase encoder. A 5V, 12V, or 24V
/FX 2N /
power source can be used. An initial value setting command input (PRESET) and a
count prohibit command input (DISABLE) are also available.
• The FX has two outputs. When the counter value coincides with an output
2NC-1HC
compare value, the appropriate output is set ON. The output transistors are
individually isolated to allow either sink or source connection methods.
• Various counter modes, such as 1-phase or 2-phase, 16-bit or 32-bit modes, can be
selected using commands from the PLC. Allow the FX
setting these mode parameters.

PRECAUTIONS
• Make sure to have the following safety circuits outside of the PLC to ensure safe
system operation even during external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection
circuit, an interlock circuit for opposite movements (such as normal vs.
*3
reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer
error, during self-diagnosis, all outputs are turned off. Also, when an error that
cannot be detected by the PLC CPU occurs in an input/output control block,
output control may be disabled.
*3
External circuits and mechanisms should be designed to ensure safe
Phase
machinery operation in such a case.
Z
3) Note that when an error occurs in a relay, triac or transistor output device, the
output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and
mechanisms should be designed to ensure safe machinery operation in such
a case.
