Chapter 9 Parameter Descriptions
Selects the source of the PI feedback signal.
Specifies the time required for the integral component to reach 100% of PI Error
Meter (137).
Sets the value for the PI proportional component when the PI Hold bit of PI
Control (125) = Enabled (1).
PI Error x PI Prop Gain = PI Output
