3.3 Automatic Operation (LOC/AUT Mode)
In automatic operation, the controller calculates and controls its output
according to a new target value. For automatic operation, control target
values must be entered by AREA number in the LOC/MAN mode.
You can choose various control operation of the actuator when you
change the set values of the PID constants. Please refer to "3.7 PID
Constants Setting and Control Operation" (page 53), and choose a
suitable control operation.
