7.6.3 Set Point Start Condition – Current PV
Selecting Current PV reduces the delay between the end of a program and the beginning of the next program. The process
variable value is used as the program start point and the set point steps up to the process variable value. This has the effect of
changing the overall segment time and maintains a constant ramp rate.
