5: output frequency reach high limit( FHL). When set frequency≥high limit
frequency and run frequency reach high limit frequency，output indicator signal.
6: output frequency reach low limit( FLL). When set frequency≤low limit
frequency and run frequency reach low limit frequency，output indicator signal.
7: Inverter stops for under voltage blockage( LU). When the inverter is
running, LED displays"P.OFF" and output indicator signal if DC bus-bar voltage is
lower than limitative level.
8: stop for exterior failure( EXT). When the inverter give the alarm (E014)
and stops for exterior failure, output indicator signal.
9 : inverter zero speed running. When the inverter output zero frequency
but
in run status, output indicator signal.
10 : In PLC run process
11: Simple PLC segment run finished. After simple PLC current segment run
is finished，output indicator signal(single pulse signal，width 500ms).
12 : PLC finish one cycle run
13 : reserved
14 : Inverter is ready for run( RDY). If this signal is effective, shows that
bus-bar voltage is normal and run prohibition terminal is ineffective, the inverter can
receive start-up command.
15 : Inverter fault. If failure takes place when the inverter is running, the
inverter output indicator signal.
16 : Traverse high&low limit restriction. After choosing traverse
function, if frequency fluctuant range based on center frequency of traverse is above
high limit frequency F0.10 or under low limit frequency F0.11, the inverter will
output indicator signal, as shown in Fig. 6-33.
