20: Set running time arrival. When VFD total running time (P3.40) reaches set
running time (P3.39), it outputs index signal.
21: upper pressure alarm signal. On closed-loop control, VFD output alarm signal
when the pipeline pressure is greater than the upper limit of pressure.
22: Lower pressure alarm signal. On closed-loop control, VFD output alarm signal
when the pipeline pressure is lower than the lower limit of pressure.

(FAR)
0.00~50.00Hz
This function is a complement to function 1 listed in Table 6-6. When VFD output
frequency is in the "+ -" detection range of set frequency, it outputs pulse signal
shown as Fig.6-25.
