PI Offset Adjustment
PI Offset
Sets the amount of offset of the output of the PI controller. Set as a% of
fmax.
The PI Offset Adjustment parameter has two different uses. Parameter
b5-07 serves different functions depending on whether it is used on a
standard PI loop or a Differential PI loop.
1: Parameter b5-07 causes an offset to be applied to the output of the PI
function in a non-Differential PI loop. Every time the PI output is
updated, the offset is summed with the PI output. This can be used to
artificially kick-start a slow starting PI loop.
2: If the Drive is configured for Differential PI Regulation (H3-09=16),
then the PI Offset is the targeted maintained differential between the
signal measured on analog input A1 and the signal measured on analog
input A2.
