P18.38
Upper limit of
pressure sensor P2
0.00
–20.00Mpa
It is related to actual range of pressure sensor.
The voltage corresponds to P18.04 is P05.44.
Note:
This value stays in current set value
during restoring to factory value.
1.60Mpa

P18.40
Auxiliary pressure
pre-alarm
0.00
–20.00
When auxiliary pressure protection function
P19.39 is enabled, and auxiliary pressure is
larger than P18.40, system releases auxiliary
pressure pre-alarm by changing BIT7 of
P19.14 to 1.

P18.41
Auxiliary pressure
alarm
0.00
–20.00
When auxiliary pressure protection function
P19.39 is enabled and auxiliary pressure is
larger than P18.41, system releases auxiliary
pressure alarm by changing BIT9 of P19.14 to
1 and emergency stop will be applied.

P18.42
Reference mode of
fan frequency
0: Temperature PID
1: Analog P2
2: 485 communication (address 0X201C,
writing of 1000 corresponds to 100.0%,
100.0% corresponds to the max. output
frequency of the fan)
0
◎
P18.43
Fan control mode
0: Air compressor mode, the fan inverter starts
and stops automatically based on the
temperature
1: Terminal, the fan inverter starts and stops
by enabling terminals.
2: 485 communication (address 0X201B, write
1 to start, write 3 to stop)
0
◎
P18.44
Automatic
frequency-reduction
threshold
0
–120%
Add automatic frequency reduction function.
When output current is larger than automatic
frequency reduction threshold, output
frequency will be adjusted by the regulator to
120%
