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
2NC
, FX
3UC
series PLC.
•
FROM/TO instruction transfers the PLC data (i.e. parameters, comparing value and
present value).
•
The FX
2NC-1HC
occupies 8 points of I/O on the FX
2NC
, FX
3UC
expansion bus. The
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
2NC
-1HC.
•
The source of your input signal should be a 1 or 2 phase encoder. A 5V, 12V, or 24V
power source can be used. An initial value setting command input (PRESET) and a
count prohibit command input (DISABLE) are also available.
•
The FX
2NC-1HC
has two outputs. When the counter value coincides with an output
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
2NC
-1HC unit to run only after
setting these mode parameters.

3.1 Wire and Terminal Tightening Torque
3.1.1
Cable
1) Applicable cable
2) Termination
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.
•
Stranded wire/solid wire
•
Bar terminal with insulating sleeve
When using a stick terminal with an insulating sleeve, choose a wire with
proper cable sheath referring to the above outside dimensions, otherwise the
wire cannot be inserted easily.
3.1.2
Tightening Torque
Tightening torque should be between 0.22 and 0.25 N•m.
Tool
To tighten terminals, use a purchased
small-sized screwdriver whose head is
straight and is not widened as shown in
the right figure.
Note:
If the diameter of screwdriver grip is too
small, tightening torque will not be able
to be achieved. Use the following recommended screwdriver or an appropriate
replacement (grip diameter: approximately 25mm).
3.2 Wiring
Note;
Make sure to properly wire in accordance with the encoder output specifications.
Incorrect wiring may cause accidents or damage to the product.
•
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, a short-circuit, wire breakage, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described
by the this manual.
- Tightening torque should follow the specifications by the this 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.

DESIGN
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.
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.
External circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
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.

However, when on 1-phase 1-input mode, UP/

Software UP/DOWN:
Up/down count is decided by the current value
(K0/K1) of BFM #1.
