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 ma in 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. Wiring

INSTALLATION 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.

INSTALLATION PRECAUTIONS

• Use the product within the generic environment specifications described in PLC main unit manual. Never use the product in areas with excessive dust, oily smoke, conductive dusts, corrosive gas (salt air,

Cl2, H2S, SO2, or NO

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

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

• Connect FX

2NC

-1HC securely to their designated connectors.

Loose connections may cause malfunctions.

• Use screwdrivers carefully when performing installation work, thus avoiding accident or product damage.

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.

3.1 Wire and Terminal Tightening Torque

3.1.1 Cable

1) Applicable cable

• 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 dimensi ons 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.

*2 Old model name: CRIMPFOX UD 6

• Stranded wire/solid wire • Bar terminal with insulating sleeve

When using a stick terminal wi th an insulating sleeve, ch oose a wire with proper cable sheath referring to the above outside dimensions, otherwise the wire cannot be inserted easily.

3.1.2 Tightening Torque

The tightening torque must be 0.22 to 0.25N•m. Do not tighten terminal screws 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 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:

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.

-1HC, connect to the power supply terminal. When using 24V DC for PRESET and DISABLE signals, connect to the 24V DC (XP24, XD24) terminal.

*3. This wiring is unnecessary when not using the PRESET funct ion and the

DISABLE function.

*2. Grounding resistance 100 Ω or less.

3.2.3 Differential-Line-Driver output encoders

When applying the Differential-Line-Driver encoder (AM26C31 or equivalent) to FX

2NC-1HC, connect the encoder output with the 5V DC terminal as shown in the left

figure.

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 (s uch 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 detec ts 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 design ed 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.

DESIGN PRECAUTIONS

• Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the control line at least 100mm (3.94") or more away from the main circuit or power line. Noise may cause malfunctions.

Counting specification

Format

Automatic UP/DOWN However, when on 1-phase 1-input mode, UP/ DOWN is determined below.

• Hardware UP/DOWN: Up/down count is decided by OFF/ON of the Aphase input terminal.

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

Range

When 32-bit is specified:

-2,147,483,648 to +2,147,483,647

When 16-bit is specified: 0 to 65,535

(upper limit is set up by BFM #3, #2.)

Comparison Type

Each output is set when the present value of the counter matches with the compare value, and is switched OFF by a reset command. YH: Direct output processed by hardware. YS: Software processed output with worst delay

time of 300μs. Therefore, when the input frequency is 50 kHz, there is a worst case delay of 15 input pulses.
