Interpret the Attribute Tables
Each attribute table begins with the attribute name as a heading. The tag,
GSV/SSV, and MSG names for each of these attributes are the same as the
attribute name listed, but with the spaces removed. For example, Inhibit Axis
would be InhibitAxis.
This table provides an explanation of the information, nomenclature, and
abbreviations used in the attribute tables.

Usage
(Implementation)
The following identifiers are used for usage:
•
Required
This is a required attribute. It is supported for the listed control modes for each
attribute.
•
Optional
This is an optional attribute. It is supported for the listed control modes for each
attribute. Optional attributes are based on the specific drive that has been
associated.
•
Replicated
For a listing of the attributes that are replicated in the drive see
Axis Attributes Based on Device Function Codes
In the Usage column, you will also see combinations of Usage and Mode, such as the
following:
C PVT Closed Loop Vector Control Method
D FC Drive (Any Frequency Controlled or Vector Controlled drive device)
In addition to these combinations there are many attributes that are applicable or
not applicable to sensorless drive operation, for example, velocity controlled drives
operating without a feedback device. To accommodate these situations, the
following Device Function Codes are used:
•
E Encoder present.
•
!E Encoderless/sensorless control, feedback device is not present.
