Setting the SP Upper and Lower Limit Values Section 4-6
range. The upper- and lower-limit values of the set point limiter are set using
the Set Point Upper Limit and Set Point Lower Limit parameters in the initial
setting level. When the set point limiter is reset, the set point is forcibly
changed to the upper- or lower-limit value of the set point limiter if the set point
is out of the limiter range. Also, when the input type and the temperature unit,
scaling upper-limit value, or lower-limit value are changed, the set point limiter
is forcibly reset to the input setting range or the scaling upper- or lower-limit
value.
Parameters
4-6-2 Setting
Set the set point upper and lower limits in the Set Point Upper Limit and Set
Point Lower Limit parameters in the initial setting level. In this example, it is
assumed that the input type is set to a K thermocouple with a temperature
range of −200 to 1300°C.
