Parameters

Configuring the SP Upper-
and Lower-Limit Values

Set Point Limiter

The maximum allowable configuration range of the set point is limited by the
set point limiter parameter. The set point limiter is used to prevent someone
from configuring the set point to some value outside the maximum range
called for by the application, thereby preventing the control target from
reaching an abnormal temperature. The upper- and lower-limit values of the
set point limiter are configured from the Set Point Upper-Limit and Set Point
Lower-Limit parameters in the Initial Setting function group, respectively.
