Output Q
Parameter
The gate time G_T can be provided by the actual value of another already-programmed function:
Analog comparator: Ax – Ay
Analog trigger: Ax
Analog amplifier: Ax
Analog multiplexer: AQ
Analog ramp: AQ
PI controller: AQ
Up/Down counter: Cnt
Data latching relay: AQ
Analog Math AQ
The value of ＂ On＂ ，＂ Off＂ can be set/modified in parameter mode. For information about how to
modify, refer to chapter 5.2.2 please.

fa = Input frequency
Description
The function count 0 to 1 transitions at input Fre. ! to 0
transitions are not counted.
Use

Inputs I5,I6 (14KHZ)I7,I8(60kHz) for ELC-12
CPU, Inputs I9,IA (14KHZ)IB,IC(60kHz) for
upgraded ELC-18,ELC-22,ELC-26 CPU

Any other input or circuit element for low
frequencies (typical 4 Hz).
On: On threshold
Range of values: 0000...9999
Off: Off threshold
Range of values: 0000...9999
G_T: Time interval or gate time during which the input
pulses are measured.
Range of values: 00:05 s...99:99 s
Q is set or reset according to the threshold values.
