Analogue Comparator 1 Value [611]
Selection of the analogue value for Analogue Comparator 1
(CA1).
Analogue comparator 1 compares the selectable analogue
value in menu [611] with the constant Level HI in menu
[612] and constant Level LO in menu [613]. When the
value exceeds the upper limit level high, the output signal
CA1 becomes high and !A1 low, see Fig. 95. When the value
then decreases below the lower limit, the output signal CA1
becomes low and !A1 high.
The output signal can be programmed as a virtual connec-
tion source and to the digital or relay outputs.

Communication information
Example
Create automatic RUN/STOP signal via the analogue refer-
ence signal. Analogue 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 vir-
tual connection destination RUN.
