master is controlled by pressure PID. The
system keeps exhaust pressure constant by
adjusting the rotation speed of the master.
Refer to section 5.2 for process logic of
pressure control.
Setting range: 0.00–P18.04
When the head temperature exceeds P18.08,
the fan starts.
fan When the head temperature is below P18.09,
the fan stops.
P18.10 is used to set the target head
the fan
temperature during stable running of the air
compressor. The rotation speed of fan is
controlled by constant temperature PID
(P18.42=0). Constant temperature control is
realized by PID calculation based on P18.10
and the head temperature.
Setting range: -20–150
P18.12–P00.04 (Upper limit of running
frequency)
Indicates the min. running frequency that the
inverter is allowed to output during the loading
process.
P01.15–P18.11 (lower limit of loaded running
frequency)
It is the working frequency allowed to be
output during no-load of air compressor.
When sleep function is valid, the inverter, after
unloading, runs at the no-load running
frequency until passing the time set by
P18.13, then it enters sleep state.
Sleep function can be enabled when the gas
consumption is relatively small. If sleep
function is valid, decrease P18.13 to make the
device enter sleep state at faster speed.
Setting range: 0–3600s
After stop command is valid, the inverter runs
at no-load running frequency until passing the
