The inverter can decide FWD run or REV run according to YCI input when
YCI is selected to be frequency provision(i.e. F0.00=6). YCI frequency defined in
F2.09 may be positive or negative when YCI isn’t selected to be frequency
provision.
Shown as the figure: 0—dead band the frequency is negative.
5V-dead band—5V+dead band YCI set frequency is 0
5V+ dead band—10V the frequency is positive

F2.00 sets the analog channel filtering time constant，to filter input signal， the
more long filtering time is, the more great anti-jamming ability is, but response
speed descend; the more short filtering time is, the more fast the inverter respond,
but anti-jamming ability is weakened.
