This parameter monitors the set point during SP ramp operation.
A ramp is used to restrict the change width of the set point as a rate of
change.
This parameter is displayed when a set value is input for the "SP ramp set
value" (adjustment level).
When not in ramp operation, the set point will be the same as the one dis-
played for the "process value/set point" parameter.
Monitor range
SP: SP lower limit to SP upper limit
