"Download para-
meter block"
object
The "download parameter block" object enables up to 38 drive parameters of the
UFI11A or an inverter connected to the UFI11A to be written at the same time with only
one write service. This object gives you the opportunity to set the parameters of the in-
verter in the startup phase, by calling the write service only once. In general, only a few
parameters vary from application to application so that this parameter block with its max.
38 parameters is sufficient for almost all applications. The user data area is defined as
38 x 6 + 2 bytes = 230 bytes (byte format). The following table shows the structure of
the "download parameter block" object.
The "download parameter block" object is only handled locally on the fieldbus interface
and is defined as in the following table.
