Explanation of Functions
Input Mode (cntm) (Setting possible using DIP switch.)
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 and so 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 112.)
Dual Count Calculating Mode (calm)
When using as a dual counter, select either ADD (addition) or SUB
(subtraction) as the calculation method for the dual count value. SUB
mode can be used only when K-2, D, L, or H is selected as the output
mode with 6-digit models.

Output Mode (outm) (Setting possible using DIP switch.)
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
and so use the operation keys if other modes are required. The out-
put 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 113.)
One-shot Output Time (otim) (Setting possible using DIP
switch.)
Set the one-shot output time (0.01 to 99.99 s) for control output.
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 and so use the operation keys if
other settings are required.
One-shot Output 2 Time (otm2) (Setting possible using
DIP switch.)
When 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). One-shot out-
put 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 and so use the operation keys if other settings
are required.
One-shot Output 1 Time (otm1)
When using as a 2-stage counter, set the one-shot output time (0.01
to 99.99 s) for control output (OUT1). 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. HOLD
cannot be set when the output mode is K-2.
Counting Speed (cnts) (Setting possible using DIP
switch.)
Set the maximum counting speed (30 Hz/5 kHz) for CP1 and CP2
inputs together. If contacts are used for input signals, set the count-
ing speed to 30 Hz. Processing to eliminate chattering is performed
for this setting.
Reset Input Signal Width (iflt) (Setting possible using
DIP switch.)
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 sig-
nals, set the counting speed to 20 ms. Processing to eliminate chat-
tering is performed for this setting.
Decimal Point Position (dp)
Decide the decimal point position for the present value, CP1/CP2
present values, set value (SV1, SV2), total count value, and dual
count set value.
Dual count value = CP1 PV + CP2 PV
Dual count value = CP1 PV − CP2 PV
Multifunction Preset Counter
Prescale Value (pscl)
Pulses input to the counter are converted according to the specified
prescale value. (Setting range: 0.001 to 99.999 for 6-digit models
and 0.001 to 9.999 for 4-digit models.)
Example: To display the feed distance for systems that output
NPN/PNP Input Mode (imod)
Select either NPN input (no-voltage input) or PNP input (voltage
input) as the input format. The same setting is used for all external
inputs. For details on input connections, refer to Input Connection on
page 96.
Display Color (colr)
Set the color used for the present value.
Note: When using as a 2-stage counter, this is the status of output 2.
Output Allocation (otst)
When using H7CX-AU@ models as a 2-stage counter, the output can
be flexibly allocated to either stage 1 or 2.
Transistor output can be allocated to SV1 and contact output for SV2
or vice verse, as in the following table.
