### VFI

is a vector variable that defines the filter at the input of the Advanced Pole-Placement velocity controller (COMPMODE = 3). The vector defined by this variable includes five integers that represent the polynomial coefficients, and two shift parameters, one that scales each polynomial. If this variable is changed, a REFRESH command is required.
