VFD Parameter Configuration
Set the parameter for function block VFD.
4.6.1 Link object
A link object combines the data voluntarily sent by the function block with the VCR. This product
has 45 link objects. A single link object specifies one combination. Each link object has the
parameters listed in Table 4.6. Parameters must be changed collectively for each VCR because
the modifications made to each parameter may cause inconsistent operation.
