Digital input 3: Reference increase. Digital input DI4: 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 3: 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 = AI(%) · (AI2(%) / 50%)
Reference is calculated with the following equation:
REF = AI1(%) + 50% - AI2(%)
Reference is calculated with the following equation:
REF = AI1(%) · (50% / AI2 (%))
A constant value defined by parameter
