Function Code Parameter Name Setting Range Default
A1-03 VDI4 function selection 0–59 0
A1-04 VDI5 function selection 0–59 0
VDI1 to VDI5 have the same functions as DI terminals on the control board and can be used
for digital input. For more details, see description of F4-00 to F4-09.
Function Code Parameter Name Setting Range Default

1: Valid
Ten's digit (VDI2)
0, 1 (same as VDI1)
Hundred's digit (VDI3)

Different from DI terminals, VDI state can be set in two modes, selected in A1-05:
• Decided by state of VDOx
Whether the state a VDI is valid is determined by the state of the corresponding VDO
and VDIx is uniquely bound to VDOx (x is between 1 and 5). For example, to implement
the function that the AC drive reports an alarm and stops when the AI1 input exceeds
the limit, perform the following setting:
1) Allocate VDI1 with function 44 "User-dened fault 1" (A1-00 = 44).
2) Set A1-05 to xxx0.
3) Allocate VDO1 with function 31 "AI1 input limit exceeded" (A1-11 = 31).
