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.
