To get details about how to specify the attribute, refer to the attributes list for the
functional category. For this example, PM Motor Resistance is a member of the
General Permanent Magnet Motor Attributes category. The following table
provides an example of the details information:
Usage Access Data
Type
Default Min Max Semantics of Values
Required Set/SSV* REAL 0
DB
0 - Ohms
* Indicates the attribute cannot be set while the drive power structure is enabled (Power Structure Enable bit in CIP Axis
Status is true).
When you are reviewing the tables for an attribute remember that Vendor Specific
attributes, attribute enumerations, and bits, are Optional by definition. Attributes
that have Optional enumerations or bit maps are designated so in the Condition
Implementation column. Details about Optional and Required support for the
individual enumerations or bits for these attributes can be found in the detailed
attribute behavior tables.
The software queries the specific drive profile, Add-on Profile (AOP), to
determine if the Optional attributes listed in the table are supported. Attributes
that are marked with an AOP in the Conditional Implementation column have
semantics with additional, drive specific, optional behavior that is queried.
If the conditional implementation column reads "Derived", it means that the value
for an attribute is determined (derived) by the controller based on the value of
another attribute. In this case, the current attribute follows the conditional
implementation rules of the attribute from which it is derived. Derived attributes
do not need to be downloaded to the controller but do need to be supported by
setting the appropriate bits in the Drive Set Attribute Update Bits attribute, if
applicable.
Conditional Implementation Key
The following table identifies the key abbreviations used in the conditional
column of the attributes tables and provides a description of the condition it
represents.
