Ray,Can you provide more details about what "disabling the axis" means? The behavior of the motor record's CNEN field, which is labeled "Torque" on the motorx_all screen, is controller dependent; for some controllers CNEN enables/disables drive power, for other controllers CNEN switches between open and closed loop control, and some drivers do nothing when CNEN is changed.
