As shown above, in this control mode, when button SB1 is closed, the frequency converter runs forward
with button SB2 pressed and runs reversely with button SB3 pressed. The frequency converter stops as soon
as button SB1 is disconnected. In the normal start and operation, button SB1 must be kept closed, while the
commands of buttons SB2 and SB3 take effect as soon as they are closed. The running state of the
frequency converter is subject to the last action of these three buttons.
3: three-line control mode 2: DI3 in this mode is an operation-enabled terminal, and the operation command
is defined by DI1, while the directions are decided by the state of DI2.
