Parameter description
running, the motor speed is controlled by
pressure PID, and the system keeps the
discharge pressure constant via adjusting
master speed. See 5.2 for details on pressure
control process logic.
Setting range: 0.00–P18.04
When the machine head temperature is
higher than P18.08, the fan starts;
When the machine head temperature is lower
than P18.09, the fan stops;
P18.10 is used to set the target temperature
of the machine head when the air compressor
runs stably, the fan speed is controlled by
thermostatic PID (P18.42=0), PID calculation
is carried out via P18.10 and the machine
head temperature to realize thermostatic
control.
Setting range: -20–150
P18.12–P00.04 (upper limit of running
frequency)
During regulating, if the pressure exceeds the
set working pressure but lower than the
unloading pressure, the allowed min. working
frequency is P18.11.
P01.15–P18.11 (lower-limit frequency of
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 stop 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
