Description
It determines the converging speed of
temperature PID regulator, the larger the
value of K, the stronger the converging
intensity, however, if
temperature oscillation may occur, users can
fine-tune based on the default value.
Setting range: 0.00–1.00
It is used to limit the output value of
temperature PID,
corresponds to max. output frequency
(P00.03) of fan.
Setting range: 0.00–100.00%
It is used to calibrate temperature detection
circuit before shipment.
Connect to the resistor whose resistance is
the same with that of PT100 at 20° C, read
the voltage value of
P18.28.
Connect to the resistor whose resistance is
the same with that of PT100 at 120° C, read
the voltage value of
P18.29.
Setting range: 0.00–10.00V
Note: This value will stay in currently set
value when restoring to default values.
0.00–P18.04
When current pressure is larger than this
pressure value, decrease the upper limit
frequency as per the set value of P18.31.
0.00Hz–10.00Hz
When current pressure is larger than the
pressure drop value of upper limit frequency,
this value is the reduction quantity of the
corresponding upper limit frequency at every
additional 0.01Mpa.
