VDO functions are similar to the DO functions on the control board. The VDO can be used
together with VDIx to implement some simple logic control.
If VDO function is set to 0, the state of VDO1 to VDO5 is determined by the state of
DI1 to DI5 on the control board. In this case, VDOx and DIx are one-to-one mapping
relationship.
If VDO function is set to non-0, the function setting and use of VDOx are the same as
'2LQJURXS)
The VDOx state can be set in A1-21. The application examples of VDIx involve the use of
VDOx, and see the examples for your reference.

Groups A2, A3 and A4 respectively correspond to motor 2, motor 3 and motor 4. The
parameters of the three groups are the same. Here we just list the parameters of group A2
for reference.
