A1.5.3 Backward Control
SC: The controlled variable output from PID is
converted into an information quantity that can be
interpreted by AO, and backward information from
AO is converted into an information quantity that
can be interpreted by PID before being transmitted
to the PID.

Figure A1.10 Backward Control (SWAP_2 = On)
To enable backward control (which inverts the X
and Y axes), the line-segment function must be
set so that the elements of the curve increase in a
monotone manner.(As shown in Figure A1.11) If
they do not increase in a monotone manner, the
mode changes to O/S, disabling calculation.
