F02.32 is used to select the corresponding offset curve for each analog input terminal.
In total, four groups of offset curves are available. Among them, the curves 1 and 2 indicate
two-point offsets, while the curves 3 and 4 indicate four-point offsets. After selecting an
offset curve, you can set the corresponding function code to meet the input requirements.
The filtering time can be adjusted according to the analog input and actual working
conditions. The actual effect will prevail.

○
This function code can be increased properly in the case of analog input hysteresis,
long input lines or excessive on-site interference resulting in significant input fluctuations.
In principle, this function code should be minimized.

Function Parameter Group of Output Terminal of F03 Group
The standard A90 series inverter is equipped with one multi-function digital output
terminal (Y1) and one relay output terminal (R1).

○
Y1 and R1 are two multi-function digital output terminals. Their functions can be
defined separately by setting the function codes F03.00 to F03.02.
For example, if you define F02.00=1, the function of the R1 terminal is “inverter
fault”. When the inverter is in the fault status, the output of the function terminal R1 will be
valid; and when the inverter is in the normal status, the output of the function terminal R1
will be invalid. Specific options are described in Table 7-6.
