If a specific logical feedback channel, feedback n, is not applicable based on the
current feedback configuration, then attributes for feedback n are not applicable;
no feedback configuration attributes for that channel are set by configuration
software, nor are any such attributes sent to the drive device. This table outlines
these rules:
Feedback Configuration Feedback 1 Feedback 2
No Feedback No No
Master Feedback Yes No
Motor Feedback Yes No
Load Feedback Yes
(1)
Yes
Dual Feedback Yes Yes
Dual Integrator Feedback Yes Yes
(1)
Feedback 1 channel is needed for commutation of PM Motors.

When configured, this attribute also sets the initial value for Feedback Mode. This
4-bit enumerated value determines how the various logical feedback channels are
used to implement the selected Control Mode for this axis instance.
Feedback Configuration enumerations provide support for multi-feedback device
control functionality for the various active device Control Modes, for example,
where the device is actively controlling the motor based on feedback. In these
