Actually, they are Yaskawa drives, and everything is in
translated Japanese-speak. They call step & driecton two-pulse,
or 2P. That is because when moving in one direction, there
would be signals on both step and direction pins at the same
time. This is opposed to their "1P" which has a CW pulse and a
CCW pulse.

Except that they are AC servo motors with proprietary encoders.
