■CHARACTERISTICS
CP1/CP2 • Count signal inputs
(count inputs) • Up, Down, and Reversible (command, individual, or phase difference) inputs accepted
• Maximum counting speed: 10 kcps
Reset • Present value reset (to zero in Up modes, to preset with single preset models in Down mode,
and to preset for double preset models)
• Count inputs are not acknowledged while reset input is ON
• Reset indicator lit while reset input is ON
Compensation On leading edge of up count signal, present count is reset to compensation value; not effective
for down count signals
Batch count reset • Batch counter is reset to zero and batch output turns OFF on leading edge
• Batch count signals are not acknowledged while batch count reset input is ON
Key protect • Reset, Mode, Teach and Increment keys are disabled according to key protect level
• Although Display key remains effective, only monitoring of settings is possible
• Key protect indicator is lit while key protect input is ON
• Effective when power supply is turned off and when key protection terminals are shorted
Gate • Input signal that interrupts the count function without resetting the counter; counting resumes once
the signal is removed

■BATCH COUNTER OPERATION (H7BR-B models)
The bold line indicates the batch count.
The batch counter counts the number of times the preset is reached for single preset models, and the number of times preset 2 is
reached for double preset models.
Notes
The batch count will remain zero while the reset input is ON.
Batches are counted, but no batch outputs are made when the
batch preset is set to zero. The batch count will return to zero if
999,999 is exceeded.
The batch count and the batch output is not reset by any method
other than the batch count reset (i.e., it is not affected by the reset
key or by other reset inputs).
If the batch output is ON when power is interrupted, it will go
ON when power is restored.
The batch output will be turned ON if the batch preset is
changed from a value greater than the present batch count to a
value less than the present batch count.
The batch output will remain ON if the batch preset is changed
from a value less than the present batch count to a value
greater than the present batch count.
Notes
Counting inputs are not acknowledged while the reset input is
ON.
The compensation input is valid only when the present value is
being incremented.
One-shot outputs, when ON, are turned OFF when the reset
input goes ON, but are left ON for the one-shot time period
when the compensation inputs goes ON. One-shot outputs,
when ON, are reset and the one-shot output is restarted if a
preset designating the output is reached.

■ EXAMPLES
Run Mode
Changing the Set Value
1. Press the DISPLAY key to change the displayed preset
value 1 and 2 during operation
2. Change the set value from 250 to 1,250.
• Press keys 1 through 6 to increment the corresponding
column by 1.
• Nonsignificant zeros are normally not shown on the set
value display.

Changing the Batch Count Set Value
1. Press the BATCH key to switch from the present value
display to the batch count display.
2. Change the set value when the counter is set to the batch
count display.
•Nonsignificant zeros are normally not shown on the
batch count set value display.
•Press the DISPLAY key to switch back from the batch
count display to the present value display.
Set Mode
Changing Settings in the Set Mode
1. Press the MODE key to switch from run mode to set mode.
•The counter will continue operation if switched from
run mode to set mode during operation.
•The MODE key will be locked if the key protect
function is enabled.
•Settings changed in the set mode do not become
effective until the run mode is entered. Because the
operating conditions change once this occurs, always
use the RESET key or a reset input to reset operation.
2. Press the MODE key to scroll successively through the items
that can be set. Release the MODE key to select the desired
item.
3. Changing the selected item:
•Press the MODE key until the desired item appears.
•Change the item setting by pressing keys 1 through 6.
(Press the DISPLAY key to switch back from set
mode to run mode.)
• Press the DISPLAY key to return to run mode from
set mode.

Teaching Mode
Changing to the Teaching Mode
1. Press the TEACH key to switch from run mode to
teaching mode.
2. When prescale teaching is not used, press MODE key to
continue teaching for the set value 1 (see next page).
Teaching for the Prescale Value
1. Set value can be set in the teaching mode.
• 0.000 is displayed on the setting position.
2. Sequence when changing a digit using the increment keys
(1 to 6).
• Displays 0 when pressing one key from the increment
keys.
3. Input the count signal of the converted value from external
sensor.
• The display to the right indicates that the controlled
object has been moved 10 cm, causing 50 counts to
be input from an external sensor.
4. Press TEACH key to set the set value.
(Set value 0.2 = 10cm/50).
• If the value input in example 3 is negative, the prescale
value will be calculated using the absolute value.
• The prescale value is rounded off to four significant
digits.
• Prescale value is displayed by teaching while pressing the
TEACH key.
