Two-line mode 1:
K1 is closed, the drive is running forward, K2 closed reverse operation, K1, K2 at the same time closed or
disconnected, the inverter stops running.
Two-line mode 2:
In K1 closed state, K2 disconnect the inverter forward, K2 closed inverter reverse; K1 off the inverter to stop
running.
Three-line mode 1:
DI3 is set to three-wire control function. When the SB1 button is closed, press the SB2 button. The inverter is
forward running. Press the SB3 button to invert the inverter. When the SB1 button is off, the inverter will stop.
During normal start-up and running, it is necessary to keep the SB1 button closed, and the commands of SB2
and SB3 buttons take effect during the closing operation. The running status of the inverter takes the last key
action of the three buttons as the standard.
Three-line mode 2:
DI3 is set to three-wire control function. When the SB1 button is closed, press the SB2 button to run the inverter,
K to switch the inverter forward, K to close the inverter and SB1 to turn off the inverter. During normal start-up
and operation, it is necessary to keep the SB1 button closed and the command of the SB2 button effective
during the closing operation.
