P18.24
Gain coefficient (kp)
It determines the adjustment intensity of
temperature PID regulator. The larger the kp,
the stronger the intensity, however, too strong
the intensity may cause temperature
oscillation. It is viable to make adjustment
based on factory value according to actual
conditions.
Setting range: 0.0
–100.0
18.0

P18.25
Convergence
coefficient (K)
It determines the convergence speed of
temperature, PID regulator. The larger the
value of K, the stronger the intensity, however,
too strong the intensity may cause
temperature oscillation. It is viable to make
adjustment based on factory value according
to actual conditions.
Setting range: 0.00
–1.00
0.12

P18.26
Upper limit of
temperature PID
It is used to limit the output value of
temperature PID adjustment. 100.00%
corresponds to the maximum output
frequency P00.03 of the fan.
Setting range: 0.00
–100.00%
100.00%

P18.27
Lower limit of
temperature PID
10.00%
○
P18.28
Lower limit voltage
of PT1 (20°C)
It is used for calibration of temperature
detection circuit in the factory:
Connect the resistor whose resistance
corresponds to PT100 at -20°C, read the
voltage value of P17.20 and input it to P18.28.
Connect the resistor whose resistance
corresponds to PT100 at 120°C, read the
voltage value of P17.20 and input it to P18.29.
Setting range: 0.00
–10.00V
Note: This value stays in current set value
during restoring to factory value.
3.10V

of PT1 (120°C)
8.10V

P18.30
Pressure value of
descending of upper
limit frequency
0.00
–P18.04
When current pressure is larger than this
pressure value, decrease the upper limit
frequency according to P18.31.
