No.
1) Counting starts by turning on CH Count enable command (RY24, RY3C).
The value in CH Present value (RWr10 to RWr11, RWr28 to RWr29) is stored in CH Latch count value (RWr12 to RWr13,
RWr2A to RWr2B), and the value in CH Preset value setting (RWw14 to RWw15, RWw2C to RWw2D) is stored in CH Present
2)
value (RWr10 to RWr11, RWr28 to RWr29) at the rising edge of CH Function input terminal (FUNC1, FUNC2). After CH Latch
count value (RWr12 to RWr13, RWr2A to RWr2B) is updated, CH Update flag (Latch count value) (RX29, RX41) turns on.
3) Set any values to CH Preset value setting (RWw14 to RWw15, RWw2C to RWw2D).
4) Counting stops by turning off CH Count enable command (RY24, RY3C).
When CH Update flag reset command (Latch count value) (RY28, RY40) is turned off then on, the high-speed counter module
turns off CH Update flag (Latch count value) (RX29, RX41) and turns on CH Update flag reset completed (Latch count value)
5) (RX28, RX40).
After that, CH Update flag reset completed (Latch count value) (RX28, RX40) turns off when CH Update flag reset command
(Latch count value) (RY28, RY40) is turned off.
6) Counting resumes by turning on CH Count enable command (RY24, RY3C).
● The count value cannot be replaced with the preset value while CH External preset/replace (Z Phase) request
detection (RX23, RX3B) is on.
Replace the value after CH External preset/replace (Z Phase) request detection (RX23, RX3B) turns off by turning on
CH External preset/replace (Z Phase) request detection reset command (RY23, RY3B).
● Have a ΔT
or longer interval after changing CH Preset value setting (RWw14 to RWw15, RWw2C to RWw2D) until the
1
value is replaced since there are maximum of ΔT
● When the latch counter function is performed by CH Function input terminal (FUNC1, FUNC2), the operation response
time follows CH Function input response time setting (address: 0129
count value (RWr12 to RWr13, RWr2A to RWr2B) is updated synchronizing with the internal control cycle, a maximum of
delay time shown below occurs until the acquired value is stored.
