Communication information
Example
Create automatic RUN/STOP signal via the analogue reference signal. Ana-
logue current reference signal, 4-20 mA, is connected to Analogue Input 1.
AnIn1 Setup, menu [512] = 4-20 mA and the threshold is 4 mA. Full scale
(100%) input signal on AnIn 1 = 20 mA. When the reference signal on AnIn1
increases 80% of the threshold (4 mA x 0.8 = 3.2 mA), the VSD will be set in
RUN mode. When the signal on AnIn1 goes below 60% of the threshold (4
mA x 0.6 = 2.4 mA) the VSD is set to STOP mode. The output of CA1 is used
as a virtual connection source that controls the virtual connection destination
RUN.
