The Feedback n Type attribute identifies the type of feedback device connected to
the associated Feedback interface. Drive support for any individual feedback types
is left to the discretion of the device manufacturer. However if a specific feedback
type is supported, attributes associated with that type are generally required in the
implementation.
When Feedback n Type is set to Not Specified, all Feedback n configuration
attribute values associated with this feedback device are considered Not Applicable
and will not be set by configuration software nor will they be sent to the drive. If
the optional Commutation Startup Method attribute is not supported by the
device, or the Commutation Startup Method is set to From Feedback Type, the
Feedback 1 Type can be used to implicitly specify the commutation startup
method.
For example, by selecting the Feedback 1 Type with or without UVW
commutation signals the device applies the UVW commutation startup method
or the Self-Sense startup method, respectively. In this case, UVW commutation
signals can be derived from UVW tracks integral to the feedback device or using
separate Hall sensors in the motor. All other Feedback 1 Type selections would
apply the Digital commutation startup method.
