Data Control Instructions Section 3-17
The following diagrams show the operation of each input read timing setting.
• Input time setting = 0 (Use the beginning value of the control period.)
• Input time setting = 1 (Use lower value.)

Duty ratio
(MV/MV range)
Each control period's output is determined by the duty ratio at the beginning of that period.
Use this setting for general applications.

is kept.
If the duty ratio falls below the initial value early enough, the duty ratio will be
adjusted and the output will be turned OFF sooner.
Use this setting for applications such as avoiding overshooting when using time-
proportional control to control heating and using a relatively long control period.
