Description
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 (%))

Addition of analog input AI1 and sequence programming output
Addition of analog input AI2 and sequence programming output
Defines the minimum value for external reference REF1. Corresponds to the
minimum setting of the used source signal.
Minimum value in rpm. Hz if parameter
SCALAR:FREQ.
Example: Analog input AI1 is selected as the reference source (value of
parameter 1103 is AI1). The reference minimum and maximum correspond to
