(1) If F5.08=0,namely 2 wire control mode 1: FWD and COM are closed，moter is
in forward run；REV and COM are closed，motor is in reverse run；FWD, REV
and COM are closed or opened together，the inverter stop.
(2) If any one or more terminal of X1, X2, X3 and COM are closed together, the
inverter will run according to multi-step speed frequency determined by X1,
X2, X3(multi-step speed frequency set value are determined by
F2.30-F2.44).Can realize manual control and automatic control for multiple
frequency, and also control for forward run, reverse run, free stop, reset,
warning protection.
