Absolute Position Feature
The absolute position feature tracks the position of the motor, within the multi-
turn retention limits, while the drive is powered off. The absolute position
feature is available with only multi-turn encoders.

IMPORTANT The Sine/Cosine encoder signal phasing is different than the TTL encoder
signal phasing.
IMPORTANT When using absolute feedback devices (for example, Stegmann Hiperface)
the drive synthesizes a marker signal because these devices don't have a
marker signal required for the home-to-marker sequence (and the marker
hookup test) to complete.
