Input circuit
CP1/CP2
Receive count signals.
Receive increment, decrement, individual, and quadrature inputs.
In increment mode and decrement mode, CP1 is used for the count input and CP2
is used for count prohibit input.
Reset
Resets the present value. (Totalizing count value is not reset.)
(In increment mode or increment/decrement mode, the present value returns to 0;
in Decrement Mode the present value returns to the set value.)
The count input is not received during resetting.
The RST indicator is lit during resetting.
Start
Starts timing.
Reset
Resets the timer. (In elapsed time mode the time returns to 0; in remaining time
mode, the time returns to the set value.)
During resetting, timing stops and the control output turns OFF.
The RST indicator is lit during resetting.
Gate
Prohibits timing operation.
OUT
Output made according to the output mode setting when the set value is reached.
