Description
The percentage of F00.03 maximum output
frequency value.
The target frequency obtained from PI
control cannot be higher than this set value.
The percentage of F00.03 maximum output
frequency value.
The target frequency obtained from PI
control cannot be lower than this set value.
Ratio coefficients 1 of target frequency PI
loop.
The larger the value, the faster the
adjustment.
Integral coefficients 1 of target frequency PI
loop.
The larger the value, the faster the
adjustment.
Ratio coefficients 2 of target frequency PI
loop.
The larger the value, the faster the
adjustment.
Integral coefficients 2 of target frequency PI
loop.
The larger the value, the faster the
adjustment.
When the deviation between actual DC bus
voltage and reference voltage is larger than
this set value, PI loop adopts coefficients 2,
otherwise adopts coefficients 1.
0: Invalid
1: Valid
0.0%: Invalid
0.1% ~ 100.0%: If the pump actual output
power is lower than this set value, the inverter
will carry out software source low protection.
Abnormal water level duration time before
source low alert.
Unit: second
Start-up delay time after water level returns
to normal.
Unit: second
When the radiator temperature is higher
0
than 75 C the reduction frequency of
maximum output frequency for every 1 C
increase.
