I/O Functions
●
Using as a Counter (See note 1.)
(1) All Modes Except for Dual Counter Mode
•
Reads count signals.
•
Increment, decrement, up/down (command, individual, or quadrature) inputs
can be used.
(2) Dual Counter Mode
•
Reads CP1 count signals on CP1 input and CP2 count signals on CP2 input.
•
Increment signals can be used.
(1) All Modes Except for Dual Counter Mode
•
Resets present value and outputs (OUT2 when using the batch counter). (See
note 2.)
•
Counting cannot be performed while resetting or when reset 1 input is ON.
•
The reset indicator is lit while the reset input is ON.
(2) Dual Counter Mode
•
Resets the CP1 present value to 0.
•
Counting the CP1 input cannot be performed while the reset 1 input is ON.
•
The reset indicator is lit while the reset 1 input is ON.
The reset operation depends on the selected function. (See note 3.)
When the corresponding set value is reached, signals are output according to the
designated output mode.
●

Key protection
input
•
Prohibits using the keys
on the front panel.
•
Set the key protection
level in function selection
mode.
Note 1.
Refer to pages 14 to 17 for information on the operation of input and output functions.
2.
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.
3.
The reset indicator will not be lit when the total reset or reset 2 input is ON.
Function
Reset operation
•
Resets the total count value.
•
Holds the total count value at 0 while the total reset input is ON.
•
Resets the batch count value and batch output (OUT1).
•
Holds the batch count value at 0 while the reset 2 input is ON.
•
Resets the CP2 present value.
•
Counting for CP2 input is disabled while the reset 2 input is ON.
Note:
For details, refer to page 24.
