1.15 Detailed Sequence of Positioner Operations

A more detailed example explains the control function. See Figure 3.
Assume the unit is configured as follows:

• Unit is in Analog command source.

• Custom characterization is disabled (therefore characterization is

Linear).

• No soft limits enabled. No MPC set.

• Valve has zero deviation with a present input signal of 12 mA.

• Loop calibration: 4 mA = 0% command, 20 mA = 100% command.

• Actuator is tubed and positioner is configured air-to-open.

Given these conditions, 12 mA represents a Command source of 50
percent. Custom characterization is disabled so the command source
is passed 1:1 to the Final Command. Since zero deviation exists,
the stem position is also at 50 percent. With the stem at the desired
position, the spool valve will be at a middle position that balances
the pressures above and below the piston in the actuator. This is
commonly called the null or balanced spool position.

Figure 2: Principles of Operation of Logix 500+

Assume the input signal changes from 12 mA to 16 mA. The position-
er sees this as a command source of 75 percent. With Linear charac-
terization, the Final Command becomes 75 percent. Deviation is the
difference between Final Command and Stem Position: Deviation =
75% - 50% = +25%, where 50 percent is the present stem position.
With this positive deviation, the control algorithm sends a signal to
move the spool up from its present position. As the spool moves, the
supply air is applied to the bottom of the actuator and air is exhausted
from the top of the actuator. This new pressure differential causes
the stem to start moving towards the desired position of 75 percent.
As the stem moves, the Deviation begins to decrease. The control
algorithm begins to reduce the spool opening. This process continues
until the Deviation goes to zero. At this point, the spool will be back
in its null or balanced position. Stem movement will stop and the
desired stem position is now achieved.

1.16 Inner Loop Offset

The position of the spool (or poppet) at which the pressures are bal-
anced, holding the valve position in a steady state, is called the Inner
Loop Offset. The controlling algorithm uses this value as a reference
in determining the Piezo voltage. This parameter is important for
proper control and is optimized and set automatically during stroke
calibration.
