Alternative control mode: this mode Din as enabled terminal, run and the rotating direction and stop
are separately controlled by Din DIy alternatively. Terminal function as below:

Alternative control mode
Din terminal must be closed before operating, the initial pulse rising by DI x DIy to control motor
forward or reverse rotating, the second pulse rising to control stop, and such repeat operation to
control inverter start/ stop. Note: DIx or DIy as start signal and meanwhile as direction signal, if as
stop signal then the effect is the same. As for the first time after the electricity through DIx terminal to
make it produce a pulse let inverter is run, the need to stop when the second pulse can be produced
by DIx delay can also be produced by the DIy, the third pulse will delay let inverter is up and run, run
direction by a third impulse signal is produced DIx or pulse produced by DIy.
At the same time, through disconnect DIn terminal signal can also achieve the downtime control
frequency converter.
Among them, the DIx, DIy, DIn is DI1 ~ DI5, HDI1 multi-function digital quantity input terminals, DIx,
DIy for pulse effectively, the DIn of level effectively.
