If Force Reference Direction (01.057) = 0 then it has no effect. If Force Reference Direction (01.057) is non-zero then the modulus of the reference is used and

the sign is defined by the value of Force Reference Direction (01.057). If Force Reference Direction (01.057) = 1 then Pre-skip Filter Reference (01.002) is

always positive, and if Force Reference Direction (01.057) = 2 then Pre-skip Filter Reference (01.002) is always zero or negative.

Alternative Reference (01.071) is provided as a destination for an alternative reference if required (such as a drive user function output).

If Alternative Reference (01.071) has been programmed as a destination, Alternative Reference Enable (01.072) is set to 1 automatically so that the alternative

reference is selected.
