factory setting
2: Three-wire operation mode 1.
• If the shift between SB2 and SB3 is disabled, the inverter will hold the control mode.
3: Three-wire operation mode 2.
• If SB2 changes from enabled into disabled, the inverter will keep the same mode.
• DIi can be selected by the multi-function input terminal DIi. At this time, the function of this terminal
should be defined as No. 4 function of “three-wire operation”.

0: Reserved. There is no output function and action of the output terminal.
1: Inverter ready. The inverter completes power on and no fault occurs, then it can normally run the
indicating signal.
2: Inverter is running. The inverter is in run status and output indicatiing signal.
3: Inverter is forward running. The inverter is forward running the indicating signal.
4: Inverter is reverse running. The inverter is reverse running the indicating signal.
5: Inverter is DC braking. The inverter is DC braking the indicating signal.
6: Inverter is in zero-frequency status. In the zero-frequency range the inverter’s output frequency
(including in stop status) outputs the indication signal.
• Refer to parameters F15.28 and F15.29.
7: Inverter is in zero-frequency running. In the zero-frequency range the inverter’s output frequency
outputs the indicating signal.
• Refer to parameters F15.28 and F15.29.
8: Reserved.
9,10: Frequency detection threshold (FDT1,FDT2).
• Refer to parameters F15.31－F15.35.
