The position feedback can be used as a reference for any unprotected parameter. The percentage of the maximum position feedback reference
(Pr x.20) is calculated and displayed via the feedback reference (Pr x.21). The value written to the destination parameter is a percentage of the full-
scale value of the destination defined by Pr x.23.
To enable a faster update rate, if the destination for the feedback is the hard speed reference (Pr 3.22), a shortcut facility is provided in the drive. In
order to invoke this facility, the maximum feedback reference (Pr x.20) must be set to the maximum currently used for the hard speed reference.
