RUN REV
In this circuit, pushing the STA FWD button would start the inverter in the forward
direction, while pushing the STA REV button would start reverse operation. If it is
desired to change rotation direction while running, the STOP button would have to be
pushed first, then the desired run direction button. That is because the inverter will ignore
a REV run command when a FWD run command is already present, and vice versa.
Pushing the buttons in this sequence will cause the inverter will ramp the motor down to
a stop, then ramp up in the opposite direction, according to its configuration settings.
