Performance Specifications of Preset Function
Refer to the following for the performance specifications of the preset function.
Outputs 0 to 3 are for counter 1 and outputs 4 to 7 are for counter 2.
External Output Pattern
(X) and (A) to (E): Horizontal lines express count values
(T):
Horizontal line expresses retention time.
(A), (C), or (E):
The number of pulses after 0 until the output is turned OFF.
(B) or (D):
The number of pulses after the preset value until the output
is turned ON.
Set the external output ON/OFF count value based on the above count val-
ues.
Note
The ON/OFF interval for outputs (e.g., the interval between (D) and (B)) must
be 2 ms min. If the interval is less than that, the output may not be correctly
executed.

External output signal
External output
0 or 4
Turned ON when the count starts and turned OFF when the counter
has counted value 0+(A).
External output
1 or 5
External output
2 or 6
Turned ON when the counter has counted preset value + (B) or preset
value + (D) and turned OFF when the counter has counted value 0+(C)
or 0+(E).
External output
3 or 7
Turned ON when the count is up and turned OFF when retention time
(T) has elapsed.
The ON status can also be retained until the beginning of the next
count.
Counter preset value
X
Range: 1 to 8,388,607
A maximum of 20 counter preset values can be set in BCD or hexadec-
imal.
The Unit cannot operate with a counter preset value of 0.

Setting range: 0 to 8,388,607 (0 to 8,388,606 for (A))
Values can be specified in hexadecimal
One value each can be set for (A), (B), (C), (D), and (E).
