In the picture of the GS4 display above, the "F" represents the PID Setpoint ( there isn't any way to

display "PID Setpoint" unfortunately). In this case, the PID SP is exactly at the mid-point ( 60.0 Psi) of the

120 Psi range we set in the step above the picture.

The bottom row, with the arrows pointing up and down on the left, and another set of arrows on the

right, is the Status line. There are approx 40 status items you can scroll left to right thru, in this case, the

"1." represents the Analog In #1 value. Note that it's at 52.14% of its' range. so it's just above the 50%

setting of 60.0 Psi for F ( 60.0 psi is 50% of 120.0 psi we set as max range in P8.03).

So the H ( Output Frequency) is 0.0, since the PID PV is slightly above the PID SP represented by F, and

the PID is happy.

In the picture below, the Analog In #1 value "1." is lowered slightly to approx 38%, and the drive starts

ramping up the H Frequency Output (here at 31.41 Hz), to try to bring the PV "1." back up to the SP of

"F".
