This parameter applies when BackwardMotionCancellationMode = FILTERED or COMPENSATE.

The motion direction is determined by the phase relationship of the A and B signals.

By construction, the dual-output phase quadrature incremental motion encoder maintains a phase relationship of about 90 degrees between the two signals. For motion in one direction, the A signal leads the B signal by about 90 degrees; for a motion in the other direction, the B signal leads the A signal by about 90 degrees.

The direction selector provides the capability to define which one of the phase relationships is considered as the forward direction for the application.

This parameter is relevant when LineRateMode=PULSE or CONVERT, and requires that LineTrigCtl=DIFF2 or ISO2.
