Virtual VDI5
Invalid 0
Valid 1
State of virtual VDI terminal can be set through 2 setting methods, which is different from common
digit input terminals, and select through A1.05.
When choosing the corresponding VDO state as the decision of VDI state , valid state of VDI is
depending on VDO output as valid or not. VDIx only binding VDOx( x
：
1~5).
Binary bits of function code A1.06 decide vitual input terminal states respectively.
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 VDI1 to “ user-defined fault 1”(A1.00=44);
Set VDO1 (A1.05=xxx0) to decide VDI1 terminal valid state;
Set VDO
1 output function to “AI1 excessive input”(A1.11=31);
When AI1 exceeding the upper / lower limit , VDO1 output ON signal, VDI1 input terminal state is
valid, VDI1
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 VDI1 to “Forward command FWD”(A1.00=1);
Set function code (A1.05=xxx1) to decide VDI1 terminal valid state;
Set VDI1 termianl to valid state(A1.06=xxx1);
Set command source to “Terminal control”(P0.02=1);
Set startup protection selection to invalid state.( P8.18=0);
After inverter power-on and the initialization, VDI1 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.
