Description
Reference decrease. Stop command resets the reference to
zero. The reference is not saved if the control source is
changed from EXT1 to EXT2, from EXT2 to EXT1 or from
LOC to REM.
Digital input DI3: Reference increase. Digital input DI4:
Reference decrease. The program stores the active
reference (not reset by a stop command). The reference is
not saved if the control source is changed from EXT1 to
EXT2, from EXT2 to EXT1 or from LOC to REM.
Reference is calculated with the following equation:
REF = AI1(%) + AI2(%) - 50%
Reference is calculated with the following equation:
REF = AI1(%) · (AI2(%) / 50%)
Reference is calculated with the following equation:
REF = AI1(%) + 50% - AI2(%)
Reference is calculated with the following equation:
REF = AI1(%) · (50% / AI2 (%))
