The Feedback Unit Ratio attribute is the number of Feedback 1 Units per
Feedback 2 Unit. This value is also used by the drive to convert between feedback
2 counts to feedback 1 counts when configured for load feedback or dual feedback
operation.

The Feedback n Unit attribute is a unit of measure for the designated feedback
device. The Feedback Unit for Feedback 1 and any redundant feedback device for
Feedback 1 must be scalable to the configured Motor Unit; if the Motor Unit is
set to Rev, Feedback 1 Unit must be set to Rev; if Motor Unit is set to Meter,
Feedback 1 Unit will be set to Meter. Feedback devices with a Feedback Unit of
Rev are considered "rotary" devices, while Feedback devices with a Feedback unit
of Meter are considered "linear" devices.
