Setting Variation Rate Limiter Setting Function

In the setting variation rate limiter setting, set the variation rate of the set value (SV) per a set unit time for when the set value
(SV) is changed. Setting variation rate limiters for the temperature rise and the temperature drop can be set in a batch or
individually.
Setting method
■Temperature rise/fall batch/individual setting
Configure the setting as follows:
[Navigation window]  [Parameter]  Target module  [Base Setting]  [Setting change rate limiter setting]

• When setting limiters in a batch
Set only "Setting change rate limiter."
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Limiter setting]
• When setting limiters individually
Set "Setting change rate limiter" and "Setting change rate limiter (Temperature drop)."
[Navigation window]  [Parameter]  Target module  [Application Setting]  [Limiter setting]
