		Reads CP1 count signals with CP1 input and CP2 count signals with CP2 input.
		Increment signals can be input.
	Reset or Reset 1	• In general (except for dual counter mode)
		Resets present value and outputs (OUT2 when using the batch counter). (See note 1.)
		Counting cannot be performed during reset/reset 1 input.
		The reset indicator is lit during reset input.
		• When used as a dual counter
		Resets the CP1 present value (to 0).
		Counting for CP1 input cannot be performed during reset 1 input.
		The reset indicator is lit during reset 1 input.
	Total Reset or	• When used as a 1-stage/2-stage counter
	Reset 2	Does not operate (Not used).
	(See note 2.)	• When used as a total and preset counter
		Resets the total count value.
		Holds the total count value at 0 during total reset input.
		• When used as a batch counter
		Resets the batch count value and batch output (OUT1).
		Holds the batch count value at 0 during reset 2 input.
		• When used as a dual counter
		Resets the CP2 present value.
		Counting for CP2 input cannot be performed during reset 2 input.
Outputs	OUT1, OUT2	Outputs take place according to designated output mode when corresponding preset is reached.

Note: 1. In increment mode or increment/decrement mode, the present value returns to 0; in decrement mode, the present value returns to the set value with 1-stage models, and returns to set value 2 with 2-stage models.

2. The reset indicator will not be lit when the total reset or reset 2 input is ON.

Note: 1. Depending on the operating environment, the condition of resin products may deteriorate, and may shrink or become harder. Therefore, it is recommended that resin products are replaced regularly.

2.The H7CX’s panel surface is water-resistive (conforming to IP66) and so even if drops of water penetrate the gaps between the keys, there will be no adverse effect on internal circuits. If, however, there is a possibility of oil being present on the operator’s hands, use the Soft Cover. The Soft Cover ensures protection equivalent to IP54F against oil. Do not, however, use the H7CX in locations where it would come in direct contact with oil.

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 23.)

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 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 24.)

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 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 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 counting 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 signals, set the counting speed to 20 ms. Processing to eliminate chattering 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).

0.5 m

25 pulses

Encoder

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 Connections on page 11.

Display Color (colr)

Set the color used for the present value.

	Output OFF (See note.)	Output ON (See note.)
red	Red (fixed)
grn	Green (fixed)
r-g	Red	Green
g-r	Green	Red

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.

H7CX-AU/-AUD1

	OUT1	OUT2
off	Transistor (12-13)	Contact (3, 4, 5)
on	Contact (3, 4, 5)	Transistor (12-13)

H7CX-AUSD1

	OUT1	OUT2
off	Transistor (12-13)	Transistor with diode
		(3, 4, 5)
on	Transistor with diode	Transistor (12-13)
	(3, 4, 5)
