  • Page 62 3-26 <Toc> <3. Programming> I Controller Behavior at the Start of Program Operation You can determine how the controller should behave at the start of program operation. 1. Letting the controller run from a starting target setpoint A starting target setpoint refers to a setpoint from which program operation begins. The controller operates in such a manner that the setpoint changes to the final target setpoint over the segment time set for segment 1, irrespective of what the PV value is.
  • Page 63 You can set a maximum of seven tempera- ture zones. When shipped from the factory, the UP750 is configured so that it operates in zone 1 only and uses only one group of PID constants.
  • Page 64 3-28 <Toc> <3. Programming> G Selection of PID Constants when the Control Range is Split into Three Zones As shown in the figure below, three zones are set for the controller to automatically switch from one group of PID constants to another. Two zones can also be set for the controller to switch between two groups of PID constants.
  • Page 65 3-29 <Toc> <3. Programming> G Selecting PID Constants According to the Deviation PID constants can be selected according to the deviation in two ways. One method is to select a group of PID constants only by a deviation from a program setpoint. The other method is to use a reference point, as discussed earlier, as well as a deviation from a program setpoint, to switch between groups of PID constants.
  • Page 66 3-30 <Toc> <3. Programming> I Retaining the End-of-Program State (Hold-mode End) This function keeps the controller in the same state as when program operation was completed. When in hold operation, the controller retains its states of control output and event output. To cancel hold operation, use either key operation or external contact input.
