1: Valid
Note: When sleep function is valid and
unloading conditions are fulfilled, the VFD
decelerates to P18.12 [no-load running
frequency], and then, if discharge pressure is
larger than P18.06 [loading pressure] during
the time set by P18.13, the VFD will
decelerate to P01.15 [stop speed] and then
coast to stop to enter sleep stage. If the
discharge pressure is less than loading
pressure during P18.13, the VFD will perform
loaded running again, and pressure PID will
regulate accordingly.

Related to the actual range of pressure
sensor, the corresponding voltage of P18.04
is P05.34.

P18.05
Unloading pressure
Under automatic loading/unloading mode,
when air compressor control is valid and the
air compressor supplies air as normal, if the
discharge pressure is higher than P18.05,
unloading automatically. If sleep function is
valid (P18.01=1), the VFD enters sleep state;
if the discharge pressure is lower than
P18.06, loading automatically. P18.07 is used
to set the air-supply pressure when the air
compressor runs stably. During load-carrying
