. When the accumulat ing time ( P3.40 ) arrive the reference time (P3.39), an indication signal
will be output.
This parameter is the additional definition of No.

function in Table4-6. As shown in Fig.4-26, when the output frequency
of inverter is within the detecting range of reference frequency, pulse signal will be output.

P4.13 ~ P4.14 is the additional definition of No.2 function in Fig.4-6, P 4.15 ~ P4.16 is the additional definition of No.3
function in Fig.4-6
,
The both have the same usage and the following take P4.13 ~ P4.14 as an example to introduce.When
the output frequency over a certain frequency( FDT1 level )
,
indication signal will be output until the output frequency fall to
the value which is lower than the certain frequency (FDT1 level - FDT1 lag ) , as shown in Fig. 4-27 .
