Goodrive300-01A series VFD for air compressor Function code description
-52-
Convergence
coefficient (K)
It determines the converging speed of
temperature PID regulator, the larger the
value of K, the stronger the converging
intensity, however, if it is too large,
temperature oscillation may occur, users can
fine-tune based on the default value.
Setting range: 0.00–1.00
Upper limit of
temperature PID
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%
Lower limit of
temperature PID
Lower limit voltage of
PT1 (-20°C )
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 150°C , read
the voltage value of P17.20 and input it to
P18.29.
Setting range: 0.00–10.00V
Note: This value will stay in currently set value
when restoring to default values.
Upper limit voltage of
PT1 (150°C )
Pressure drop value of
upper limit frequency
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.
Drop rate of upper limit
frequency
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.
Lower limit voltage of
PT2 (-20°C )
It is used to calibrate the temperature
detection circuit:
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
Upper limit voltage of
PT2 (150°C )
