P31.06 - P31.13 are the time constants for setting the signal action delay and reset delay of the
output terminals K1 – K2 and Y0 - Y1. By using these terminals, the delay time of the output state of
each output terminal relative to its corresponding actual signal can be flexibly set as required.
Moreover, the delay time of the above-mentioned output state can be set separately when the signal
is triggered or when the signal is reset.

Zero current detection width (%)
0.0~50.0
4.0
This function can be used for load change detection. Set the output terminal function to "15: zero
current detected", and output the indicating signal after the output current of the inverter is lower
than the zero current detection width set by P31.20.
When the inverter stops, if the inverter current is greater than the threshold, the corresponding output
terminal set by function code 15 (or 115) acts.
Note: This function parameter is the percentage of inverter output current relative to motor rated
current.

P31.21 this function is used for deviation detection between output frequency and set frequency.
Setting the output terminal function to "4: Frequency arrival signal", the deviation between the
output frequency and the set frequency of the inverter is within the setting range of this function
code. Output indication signal, as shown in the figure, frequency arrival signal FAR.
