Description
P01.15–P18.11 (lower-limit
load-carrying running)
The output working frequency allowed during
no-load of air compressor.
When sleep function is valid, after unloading,
the VFD runs at no-load frequency in the time
set by P18.13, and then enters sleep state.
When air consumption quantity is small, users
can enable sleep function; if sleep function is
valid, it is necessary to lower down P18.13 to
make the device enter sleep state quicker.
Setting range: 0–3600s
After the stopping command becomes valid,
the VFD will first run at no-load frequency in
the time set by P18.14, and then stops.
Setting range: 0–3600s
Loading operation is available only after the
motor runs at no-load frequency in the time
set by P18.15.
Setting range: 0–3600s
After the system stops, it is necessary to wait
until the time set by P18.16 elapsed before
restart.
Setting range: 0–3600s
When current discharge pressure is higher
than P18.17, the system indicates pressure
pre-alarm by setting BIT8 of P19.13 to 1.
When current discharge pressure is higher
than P18.18, the system indicates pressure
alarm by setting BIT10 of P19.13 to 1, and
emergency-stop will be applied.
Setting range: 0.00–P18.04
than P18.19, the
temperature pre-alarm by setting BIT9 of
P19.13 to 1.
When the machine head temperature is
higher than P18.20, the system indicates
temperature alarm by setting BIT11 of P19.13
