P18.31
Reduction rate of
upper limit
frequency
0.00Hz
–10.00Hz
It is the reduction quantity of the
corresponding upper limit frequency for each
additional 0.01Mpa when current pressure is
larger than P18.30.
0.00Hz
○
P18.32
Lower limit voltage
of PT2 (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 PP17.22 and input it to
P18.32.
Connect the resistor whose resistance
corresponds to PT100 at 120°C, read the
voltage value of P17.22 and input it to P18.33
Setting range: 0.00
–10.00V
Note:
This value stays in current set value
during restoring to factory value.

-20
–150
When P18.34 is enabled and the auxiliary
temperature exceeds P18.35, the system
releases auxiliary temperature pre-alarm by
changing BIT8 of P19.14 to 1.

–150
When P18.34 is enabled and the auxiliary
temperature exceeds P18.36, system
releases auxiliary temperature alarm by
changing BIT10 of P19.14 to 1 and
emergency stop will be applied.
