Functional Description 133
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 thresh-
old (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 connec-
tion source that controls the virtual connection destina-
tion RUN.

No. Description
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 refer-
ence signal.
4
The reference signal reaches the threshold level, motor
speed is 0 rpm, mode = RUN.
5
The reference signal passes the Level HI value from
above (negative edge), the comparator CA1 output stays
high, mode =RUN.
6
The reference signal passes the Level LO value from
above (negative edge), the comparator CA1 out-
put=STOP.
Default: 300 rpm
Range: Enter a value for the high level.
