9.3.1 Static Access to Parameters
Instances 20 - 23 and 70 - 73 in the Assembly Object are defined by the AC/DC drive profile. The setup
of these instances is predefined and can not be changed by the user. Instances 150 and 100 also have
predefined setups, but can be used for user specific data mapping, see below.
9.3.2 Vendor Specific Access to Parameters
Instances 150 and 100 in the Assembly object are available for vendor specific access. If Prepend is enabled (see “Parameter 514h / Pr. 1300 (General Settings)” on page 38), the information in the selected
assembly instance will be prepended the user specific data. This is e.g. useful when exchanging control/
status word data, that you can only find in the predefined assembly instances.
For more information see “Assembly Object (04h)” on page 61.
