Setting the Valve Stroke Time
This is the procedure for setting the valve stroke time to add
servo control.
The following steps explain how to set valve stroke time by
using 50 seconds as an example.
Position Feedback Control (PFB Control)
Position feedback control (PFB) controls the position of the
motorized valve based on the opening signal from the valve.
In manual mode, the opening signal from the motorized valve
will display as the MV value.
This method controls based on the actual valve position
(opening signal), and therefore can provide a more accurate
control than servo control 1or servo control 2.
