17: Interior counter reach final value
18: Interior counter reach specified value
17~18 please refer to function description of F5.25~F5.26.
19: Set runtime arrive. When accumulative runtime of the inverter (F2.52)
reach set runtime(F2.51)，output indicator signal.
20: Interior timing arrive. Refer to function description for F5.27.

F5.14 Freq. arriving(FAR)detect range
Range: 0.00－50.00Hz
5.00Hz
This parameter is supplementary definition to No. 1 function in Table 6-8.As
shown in Fig.6-34，when output frequency of the inverter is within high&low
detect range of set frequency，output pulse signal.
F5.15
FDT1(freq. level) electric level
Range: 0.00－high
limit frequency
10.00Hz
F5.16
FDT1 lag Range: 0.00－50.00Hz
1.00Hz
F5.15~F5.16 is supplementary
definition to No.2 function in Table
6-8, introduce as follows: When
output frequency exceed the set
frequency(FDT1 electric level) ，
output indicator signal ， till output
frequency descend to be some
frequency(FDT1 electric level-FDT1
lag) lower than FDT1 electric level，
as shown in Fig.6-35.
