(E3.11=31); so when AI1 input exceeds upper or lower frequency, VDO1 state is ON, VDI1 input
terminal state is effective, VDI1 receive user defined fault 1, inverter then alarm fault no. 27 and
shuts down.
Example 2. Implement following function: “Inverter run automatically after power-on”.
Realize by following settings: set VDI state decided by function code E3.05, set VDI1
function as “FORWARD” (E3.00=1); set VDI1 terminal state effective decided by function code
(E3.06=xxx1); set VDI1 terminal state is effective (E3.05=xxx1); set command source as “terminal
control” (F0.11=1); set protection selection as “no protection” (F7.22=0); so after inverter powered
on and initialization complete, VDI1 detected effective, and it match forward running, then
inverter starts running forwardly.

This group function code is used when using AI as DI, when AI used as DI, and input voltage
of AI is greater than 7V, AI terminal status will be high level, when input voltage of AI is lower
than 3V, AI terminal status will be low level. For between 3V~ 7V hysteresis E3.10 is to determine
that when the AI is used as DI, AI is made valid by means of the high level state, or the low level
of valid states. As for AI as DI feature set, same as the ordinary DI Settings, please refer to the F1
group setting instructions related DI. Below figure is AI input voltage taken as an example,
explains the relationship between input voltage of AI and the corresponding state of DI:
