Note: Depending on the operating
environment, the condition of resin parts
may deteriorate, and may shrink or
harden. Therefore, it is recommended
that resin parts are replaced regularly.
Product Protection for Use in
Environments Subject to Water or Oil
The panel surface has a protective
structure so that the internal circuits will
not be adversely affected if drops of water
penetrate the gaps between the keys. If,
however, there is a possibility of water or
oil being present on the operator's hands,
mount the optional Soft Cover.
The Soft Cover ensures protection
equivalent to IP54. Do not, however, use
the H7BX in locations where it would come
into direct contact with oil.

H7BX
Explanation of Functions
Settings marked with a star can be performed with the DIP switch.
• Input Mode (cntm) ★
• Reset Input Signal Width (iflt) ★
Set increment mode (UP), decrement mode (DOWN), or one of the
increment/decrement modes (UP/DOWN A, UP/DOWN B, or UP/
DOWN C) as the input mode. Input modes other than UP or DOWN
modes cannot be set using the DIP switch. Use the operation keys if
other modes are required. (For details on the operation of the input
modes, refer to Input Modes and Present Value on page 13.)
Set the reset input signal width (20 ms/1 ms) for reset/reset 1 and total
reset/reset 2 inputs together. If contacts are used for input signals, set
the counting speed to 20 ms. Processing to eliminate chattering is
performed for this setting.
• Dual Count Calculating Mode (calm)
When the H7BX using as a dual counter, select either ADD (addition)
or SUB (subtraction) as the calculation method for the dual count
value.
ADD: Dual count value = CP1 PV + CP2 PV
SUB: Dual count value = CP1 PV − CP2 PV
• Output Mode (outm) ★
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, A, K-2, D, L, and H. Output
modes other than N, F, C, or K-1 cannot be set using the DIP switch.
Use the operation keys if other modes are required. The output
modes that can be set vary with the model. (For details on the
operation of the output modes, refer to Input/Output Mode Settings on
page 14.)
• Decimal Point Position (dp)
Decide the decimal point position for the present value, CP1/CP2
present values, set values (SV1, SV2), total count value, dual count
value and dual count set value.
• Prescale Value (pscl)
Pulses input to the counter are converted according to the specified
prescale value.
Setting range: 0.001 to 99.999
Example: To display the feed distance for systems that output
25 pulses for a feed length of 0.5 m in the form @@.@@ m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5 ÷ 25).
0.5 m
• One-shot Output Time (otim) ★
Set the one-shot output time (0.01 to 99.99 s) for the control output.
A one-shot output can be used only when C, R, K-1, P, Q, A, or K-2
is selected as the output mode. Output times other than 0.5 s or 0.05
s cannot be set with the DIP switch. Use the operation keys if other
settings are required.
25 pulses
Encoder
• One-shot Output 2 Time (otm2) ★
When the H7BX using as a 2-stage counter or batch counter, set the
one-shot output time (0.01 to 99.99 s) for control output (OUT2). A
one-shot output can be used only when C, R, K-1, P, Q, A, or K-2 is
selected as the output mode. Output times other than 0.5 s or 0.05 s
cannot be set with the DIP switch. Use the operation keys if other
settings are required.
• One-shot Output 1 Time (otm1)
When the H7BX using as a 2-stage counter, set the one-shot output
time (0.01 to 99.99 s) for control output (OUT1). A one-shot output
can be used only when D, L, or H is selected as the output mode. If
the output time is set to 0.00, hold is displayed, and outputs are held.
• Counting Speed (cnts) ★
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2
inputs together. If contacts are used for input signals, set the counting
speed to 30 Hz. Processing to eliminate chattering is performed for
this setting.
Note: Incorrectly setting the prescale value will result in counting
errors. Check that the setting has been performed correctly
before using the H7BX.
• NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. For 2-wire sensors, set the format to NPN
input. The same format setting applies to all external inputs. For
information on input connections, refer to page 6.

H7BX
Total and Preset Counter Operation
The H7BX has a total counter separate from the 1-stage preset counter for counting the total accumulated value.
• The total counter continues to count the total
accumulated value when the present value is
reset using reset/reset 1 input (Reset Key).
• The total count value is reset when the total
reset/reset 2 input is turned ON.
If the Reset Key is pressed while the total
count value is displayed, the total count
value is reset. The present value is also
reset at this time.
• The counting range of the total counter is
−99,999 to 999,999. The total count value
returns to 0 when it reaches the full scale limit.

The batch count value is held at 0 while the batch counter reset input is on.
If the batch count set value is 0, batch count will be performed but there will be no batch output.
The batch count value returns to 0 when it reaches 999,999.
Once batch input has been turned ON, it will return to the ON state after power interruptions.
If the batch count set value is changed from a value that is greater than the batch count value to one that is less, batch output will turn ON.
After batch output turns ON, the ON state will be held even if the batch count set value is changed to a value greater than the batch count
value.
Dual Counter Operation
Using the dual counter allows the count from 2 inputs to be added or subtracted and the result displayed. It is possible to specify a set value for
which output turns ON when the set value matches the added or subtracted result.

values are reset and the outputs turn OFF.
At this time, counting is not possible for CP1
or CP2 inputs.

Note: The above is for when the output mode is K-2.
SUB mode can be used only when K-2, D, L, or H
is selected as the output mode with 6-digit models.
Note: 1. Counting is not possible for CP1 while the reset 1 input is ON. CP2 is not affected. The dual count value will be calculated based on a
CP1 present value of 0.
2. Counting is not possible for CP2 while the reset 2 input is ON. CP1 is not affected. The dual count value will be calculated based on a
CP2 present value of 0.
3. The counting range for the dual count value is −99,999 to 999,999.
The counting ranges for the CP1 present value and CP2 present value are 0 to 999,999.
If a present value exceeds 999,999, FFFFFF will be displayed to indicate an overflow, and all counting will stop.

H7BX
Explanation of Functions
Settings marked with a star can be performed with the DIP switch.
• Tachometer Output Mode (totm) ★
• Auto-zero Time (avt) ★
Set the output method for control output based on the OUT1/OUT2
set value. Upper and lower limit (HI-LO), area (AREA), upper limit
(HI-HI), and lower limit (LO-LO) can be set.
(For details on the operation of the output modes, refer to Output
Mode Settings on page 22.)
It is possible to set the H7BX so that if there is no pulse for a certain
time the display is force-set to 0. This time is called the auto-zero time.
Set the auto-zero time to a time slightly longer than the estimated
interval between input pulses. It will not be possible to make accurate
measurements if the auto-zero time is set to a time shorter than the
input pulse cycle. Setting a time that is too long may also result in
problems, such as a time-lag between rotation stopping and the alarm
turning ON.
• Counting Speed (cnts) ★
Set the maximum counting speed (30 Hz/10 kHz) for CP1 input.
If contacts are used for input signals, set the counting speed to 30 Hz.
Processing to eliminate chattering is performed for this setting.
• Decimal Point Position (dp)
Decide the decimal point position for the measurement value, OUT1
set value, and OUT2 set value.
• Prescale Value (pscl)
It is possible to display the rate of rotation or the speed of a device or
machine to which the H7BX is mounted by converting input pulses to
a desired unit. If this prescaling function is not used, the input
frequency (Hz) will be displayed.
The relationship between display and input is determined by the
following equation. Set the prescale value according to the unit to be
displayed.
• Startup Time (stmr)
In order to prevent undesired output resulting from unstable input
immediately after the power supply is turned ON, it is possible to
prohibit measurement for a set time. This time is called the startup
time.
It can also be used to stop measurement and disable output until the
rotating body reaches the normal rate of rotation, after the power
supply to the H7BX and rotating body are turned ON at the same time.

Example: In order to display the rate of rotation for a machine that
outputs 5 pulses per revolution in the form @@.@ rpm:
1. Set the decimal point position to 1 decimal place.

Note: Incorrectly setting the prescale value will result in
counting errors. Check that the setting has been
performed correctly before using the H7BX.
• Average Processing (aug) ★
Flickering display and output chattering can be prevented by using
average processing (simple averaging). Average processing can be
set to one of four levels: no average processing, 2 times (i.e., the
average of 2 measurement values), 4 times, or 8 times.
The measurement cycle will be equal to the sampling cycle (200 ms)
multiplied by the average processing setting (i.e., the number of
times). Average processing enables fluctuating input signals to be
displayed stably. Set the optimum number of times for the application.

H7BX
Safety Precautions
Refer to Safety Precautions for All Counters.
Caution
Minor injury due to electric shock may occasionally
occur. Do not touch any of the terminals while power is
being supplied.
Fire may occasionally occur. Tighten the terminal
screws to a torque of 0.5 to 0.6 N·m (4.4 to 5.3 in-lb).
Minor injury due to explosion may occasionally occur.
Do not use the H7BX where subject to flammable or
explosive gas.
If the output relay is used beyond its life expectancy, its
contacts may become fused or there may be a risk of
fire.
Use the output relay within its rated load and electrical
life expectancy. The life expectancy of the output relay
varies considerably according to its usage.
Minor electric shock, fire, or malfunction may
occasionally occur. Never attempt to disassemble,
modify, or repair the H7BX or touch any of the internal
parts.
Precautions for Safe Use
Operating Environment
• The H7BX is intended for indoor use only. Do not use the H7BX
outdoors or in any of the following locations.
• Locations subject to sudden or extreme changes in temperature.
• Locations where high humidity may result in condensation.
• Locations subject to direct sunlight.
• Locations subject to corrosive gas.
• Locations subject to excessive dust or dirt.
• This is a class A product (for industrial environments). In residential
areas, it may cause radio interference, in which case the user may
be required to take adequate measures to reduce interference.
• Use the H7BX within the specified ratings for operating
temperature and humidity. Temperature rise may shorten the
service life of H7BX if it is used near a power supply or other
heat-generating objects.
• Use the H7BX within the specified ratings for vibration, shock, and
splashing water.
• The H7BX is not oil resistant. Do not use it in locations subject to
oil.
• Install the H7BX well away from any sources of excessive static
electricity, such as pipes transporting molding materials, power, or
liquids.
• Store the H7BX within the specified ratings. If the H7BX has been
stored at temperatures of −10°C or lower, let it stand for 3 hours or
longer at room temperature before turning ON the power supply.
Power Supply
• Maintain voltage fluctuations in the power supply within the
specified range.
• Internal elements may be destroyed if a voltage beyond the rated
voltage is applied.
• When the power is turned ON, an inrush current will flow for a short
time (approx. 10 A for 2 ms). Depending on the power supply
capacity, operation may not start. Be sure to use a power supply
with a sufficient capacity.
• Use a commercial power supply as the AC power supply for the
H7BX. Using an inverter output with an output frequency of 50/60
Hz as the power supply may cause the H7BX to produce smoke or
become damaged by burning.
• Use a switch, relay, or other device with contacts so that the rated
power supply voltage will be reached within 2 s. If the power supply
voltage is not reached quickly enough, the outputs may
malfunction.
• Use a switch, relay, or other device with contacts so that the rated
power supply voltage will be reached within 2 s. If the power supply
voltage is not reached quickly enough, the outputs may
malfunction.
Installation and Wiring
• To mount the H7BX to a panel, attach the two supplied adapters to
the left and right sides of the H7BX, and securely tighten the
knurled screws on the adapters by hand, maintaining a balance
between them. Damage may result if the knurled screws are
excessively tightened with pliers or other tools.
• Be sure to wire the terminals correctly.
• Up to two wires of the same size and type can be inserted into a
single terminal.
• Do not connect more than two crimp terminals to each H7BX
terminal.
• Use the specified wires for wiring.
Applicable wire: AWG 24 to AWG 18 (equal to a cross-sectional
area of 0.20 to 0.82 mm2)
Solid wire or twisted wire (copper), operating temperature over
70°C.
• Separate the H7BX, the devices that generate input signals, and
input signal wires from any potential sources of noise, such as
high-voltage lines.
Handling
• Do not use organic solvents (such as paint thinner or benzine),
strong alkaline, or strong acids because they will damage the
external finish.
• Approximately 14 V will be output to the input terminals when the
H7BX is used with the key protection input terminals and
no-voltage input (NPN input) is used. To prevent charging
accidents, connect a diode to the power supply circuit of input
devices if input devices are used with a power supply of less than
14 V.
• Do not connect loads that exceed the rated output current. The
output elements may be destroyed, possibly resulting in
short-circuit or open-circuit faults.
• When using heaters, be sure to use a thermal switch for the load
circuit.
• Always connect a diode to protect against counter electromotive
force when using an inductive load. H7BX electromotive force may
destroy output elements, possibly resulting in short-circuit or
open-circuit faults.
• Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate its
function.
• Check that the display (backlight and LCD) is operating normally.
Some operating environments may accelerate deterioration of the
indicators, LCD, and resin components and cause display
malfunctions. Periodically inspect and replace parts.
25
H7BX
Precautions for Correct Use
• Inrush current generated by turning ON or OFF the power supply
may deteriorate contacts in the power supply circuit. Turn ON or
OFF using a device with a rated current of 10 A or higher.
• Input signals may be accepted, not accepted, or unstable for the
following time when the power supply is turned ON or OFF. Set the
system to allow leeway in the timing of input signals.
Power supply ON
OFF
200 ms 0 to 90 ms

Load current (mA)
• This H7BX always compares the count value with the set value.
Thus, if you change the set value during operation, please
remember that the output will turn ON when the set value becomes
equal to the count value.
• With the factory setting, the output will turn ON when power is
supplied to the H7BX because the set value and count value are
both zero. While resetting, however, the output stays OFF.
• EEPROM is used as memory when the power is interrupted. The
write life of the EEPROM is 100,000 writes. The EEPROM is
written when settings are changed, or the power is tuned OFF.
• Water resistance will be lost if the front sheet is peeled off or torn.
Do not use the H7BX if the front sheet is missing or torn.
• Abide by all local ordinances and regulations when disposing of the
H7BX.
• External Power Supply
Reduce the load current as shown in the diagram on the right
according to the power supply voltage if a DC power supply is used
for models specified for 24 VAC/12 to 24 VDC.
