Description
Summation of fieldbus reference REF1 and analog input AI.
See section Reference selection and correction
320.
Multiplication of fieldbus reference REF1 and analog input
AI1. See section Reference selection and correction
page 320.
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 2205 ACCELER TIME 2
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
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 copied 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 copied if the control
source is changed (from EXT1 to EXT2, from EXT2 to
EXT1).
