When the running frequency is higher than the frequency detecion values, the frequency converter
multi-function output DO output ON signal, and the frequency is lower than a certain frequency values
of the detection values, the DO output ON signal is cancelled.
The above parameters are used to set the detection value of output frequency, and cancel the lag
value of the output motion. Among them, the Fb-17 (Fb-19) is the percentage of lagging frequency
relative to the frequency detection values Fb- 6 (Fb-18). The diagram below for the FDT function.
