The output signal can be programmed as a virtual
connection source and to the digital or relay outputs.
Example
Create automatic RUN/STOP signal via the analogue
reference 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 AC drive 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 AC drive is set to
STOP mode. The output of CA1 is used as a virtual
connection source that controls the virtual connection
destination RUN.

1
The reference signal passes the Level LO value from
below (positive edge), the comparator CA1 output
stays low, mode=RUN.
2
The reference signal passes the Level HI value from
below (positive edge), the comparator CA1 output is
set high, mode=RUN.
3
The reference signal passes the threshold level of 4
mA, the motor speed will now follow the reference
signal.
T
During this period the motor speed will follow the
reference signal.
