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). Parameter
the rate of the reference change.
Digital input DI3: Reference increase. Digital input DI4:
Reference decrease. The program stores the active speed
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). When the
drive is restarted, the motor ramps up at the selected
acceleration rate to the stored reference. Parameter
ACCELER TIME 2 defines the rate of the reference change.
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 (%))
command resets the reference to zero (the R stands for
reset.). The reference is not saved if the control source is
changed (from EXT1 to EXT2, from EXT2 to EXT1).
Defines the control panel as the reference source. Stop
command does not reset the reference to zero. The
reference is stored. The reference is not saved if the control
source is changed (from EXT1 to EXT2, from EXT2 to
EXT1).
See selection DI3U,4D.
See selection DI3U,4D(NC).
Frequency input
Defines the minimum value for external reference REF1.
Corresponds to the minimum setting of the used source
signal.
