Multifunction Preset Counter

H7CX (Counter Function)

C-109

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.

ADD:

Dual count value = CP1 PV + CP2 PV

SUB:

Dual count value = CP1 PV

− CP2 PV

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.

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

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).

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.
