1.3 Coincidence Output Function
1.3 Coincidence Output Function
This function compares the present count value with the preset count value, and outputs a signal when they match.
Setting method
1. Set "Counter operation mode" to "Pulse count mode".
2. Set a count value for "Coincidence output point No.1 setting" or "Coincidence output point No.2 setting".

setting]
Up to two coincidence outputs can be set for each channel.
When the external output of the coincidence signal is used, turn on CH1 Coincidence signal enable command (Y2)
beforehand.
Operation of the coincidence output
Item Setting range
Coincidence output point No.1 -2147483648 to 2147483647
Coincidence output point No.2
No. Description
(1) The comparison operation starts with the value set to CH1 Coincidence output point No.1 setting (Un\G4 to Un\G5).
(2) When CH1 Present value (Un\G2 to Un\G3) becomes less than CH1 Coincidence output point No.1 setting (Un\G4 to Un\G5), CH1 Counter
value smaller (point No.1) (X3) turns on.
(3) When CH1 Coincidence signal No.1 reset command (Y0) is turned on, CH1 Counter value coincident (point No.1) (X2) and the coincidence
output point No.1 terminal (EQU1) turns off.
(4) If a coincidence output from the coincidence output point No.1 terminal (EQU1) is required, turn on CH1 Coincidence signal enable command
(Y2).
