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.

If the duty ratio rises above the initial value early enough, the duty ratio will be
adjusted and the output will be turned ON sooner. (With this setting the output's
ON/OFF order is reversed and the output goes from OFF to ON.)
Use this setting for applications such as avoiding undershooting when using time-
proportional control to control cooling and using relatively long control period.
