The following example illustrates the method of using virtual VDI.
E.g1
：
When choosing VDO state deciding VDI state, to complete “AI1 input exceeding limit,
inverter fault alarm and stop”
：
Set VX1 to “ user-defined fault 1”(A1.00=44);
Set VDO (A1.05=xxx0) to decide VX1 terminal valid state;
Set VDO output function to “AI1 excessive input”(A1.11=31);
When AI1 exceeding the upper / lower limit , VDO output ON signal, VX1 input terminal state is
valid, VX1 receives “ user-defined fault 1”, and inverter fault alarm and stop , fault No. 27= E.USt1.
E.g2
：
When choosing function code A1.06 deciding VDI state, to complete “ Auto into running
state after power-on ”
：
Set VX1 to “Forward command FWD”(A1.00=1);
Set function code (A1.05=xxx1) to decide VX1 terminal valid state;
Set VX1 termianl to valid state(A1.06=xxx1);
Set command source to “Terminal control”(F0.02=1);
Set startup protection selection to invalid state.( F8.18=0);
After inverter power-on and the initialization, VX1 is detected as valid, the terminal corresponding
to forward running, which is equivalent to inverter receiving a forward running command, and then start
forward running.

AI is used as DI for this function group. AI input voltage is greater than 7V, corresponding AI terminal
state is high level. AI input voltage is less than 3V, corresponding AI terminal state is low level. 3V~7V for
hysteresis loop .
Whether AI (as DI) high level valid or low level valid is determined through function code A1.10. For
AI(as DI) function settings, they are same with common DI settings, for details please refer to F4 group .
Fig. 5-31 takes AI input voltage as an example, explains the relationship between AI input voltage and
corresponding DI state
