DL100 Series Universal Low-Power Inverter
46 Detailed Description of Functions
0：Inverter is running
When the inverter is running, it outputs an effective signal, and when it is
stopped, it outputs an invalid signal.
1： Frequency arrives
When the output frequency of the inverter is close to the set frequency to a
certain range (the range is determined by parameter [F4.07]), it outputs a valid
signal, otherwise it outputs an invalid signal.
2： Frequency level detection (FDT)
When the output frequency of the inverter exceeds the FDT frequency level, the
effective signal will be output after the set delay time. When the output frequency
of the inverter is lower than the FDT frequency level, the invalid signal will be
output after the same delay time.

For When connecting inductive components (such as
relay coils), freewheeling diode D must be connected
in parallel.
connecting external inductive elements (e.g. relay coil),
freewheel diode D must to be connected in parallel.
