Unipolar = Drive receives unsigned reference (0...32767) and
direction command separately (from the DPI port). For
example, the direction keys on an OIM apply the
direction to the reference.
Bipolar = Drive receives signed reference (-32767...32767). In this
case, the direction keys have no effect.
Reverse Disable = Drive receives signed reference (-32767...32767);
however, regardless of the reference, the drive is not
permitted to reverse.
