Description
to 1, and emergency-stop will be applied.
When machine head temperature is lower
than P18.21, the
low-temperature pre-alarm by setting BIT14 of
P19.13 to 1, and air compressor cannot start.
Setting range: -20–150
It is used to calibrate the displayed value of
P19.10 [actual motor output power].
Setting range: 0%–200%
Set the sampling cycle of temperature PID.
Setting range: 0.0–10.0s
It determines the regulation intensity of
temperature PID regulator, the larger the
value of kp, the stronger the regulation
intensity, however,
temperature oscillation may occur, users can
fine-tune based on the default value.
Setting range: 0.0–100.0
It determines the converging speed of
temperature PID regulator, the larger the
value of K, the stronger the converging
intensity, however,
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, of which 100% corresponds
to the P00.03 max. output frequency 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 P17.20 and input it to
P18.28.
Connect to the resistor whose resistance is
the same with that of PT100 at 120° C, read
the voltage value of P17.20 and input it to
-70-
