Operation of Time-proportional Output DOut for Minimum Pulse
Width MinPlsWidth
The minimum pulse width is the minimum time that DOut will retain a value of TRUE or FALSE. You can
set minimum pulse width MinPlsWidth to reduce chattering in DOut. For example, if the number of times
a fan is turned ON and OFF is reduced in cooling control, power consumption is reduced.
The following table shows the operation of DOut for the relationship between the values of MinPlsWidth
and AIn.
Relationship between the values of MinPlsWidth and AIn
AIn < MinPlsWidth
MinPlsWidth ≤ AIn ≤ 100 − MinPlsWidth
AIn > 100 − MinPlsWidth
For example, the following figure shows the operation of DOut when MinPlsWidth is 30%. If the value of
AIn is greater than 70%, DOut is always TRUE. When AIn decreases to 70% or lower, DOut operates
for the time-proportional output.

If the value of AIn is less than 30%, DOut is always FALSE. When AIn increases to 30% or higher, DOut
