P18.32
PT2 calibration
voltage 1 (20
℃
)
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 P17.22 and input it to
P18.32 .
Connect to the resistor whose resistance is
the same with that of PT100 at 120°C, read
the voltage value of P17.22 and input it to
P18.33 .
Setting range: 0.00
–10.00V
Note:
1. This value will stay in currently set value
when restoring to default values.
2. PT2 is on the expansion card, so P18.32
and P18.33 make sense only when an
expansion card is connected. If no
expansion card is connected, both
parameters are 0.

When P18.34 is enabled and auxiliary
temperature is higher than P18.35 , the
system indicates auxiliary temperature
pre-alarm by setting BIT8 of P19.14 to 1.

When P18.34 is enabled and auxiliary
temperature is higher than P18.36 , the
system indicates auxiliary temperature alarm
by setting BIT10 of P19.14 to 1, and
emergency-stop will be applied.
