: Synchronized movement from the main shaft
Sync request from the master cam of the cam shaft of the cam phase satisfy the relationship
defined by the engagement process was synchronized phase process from moving toward the axis
of the spindle and the cam phase synchronous phase satisfy the relationship defined by the cam.
Since the phase of the cam shaft having a cyclical characteristic, i.e., each cam has a plurality of
phase-axis position corresponding thereto, when engaged, there are alternative desired
synchronization position, there is such a wide selection of engaging manner. For example: the start
of execution engagement cam from the phase of the main axis are 80 and 180 (e.g., O lower right
in the drawing), but the requirements defined by the phase relationship of the cam from the cam
shaft 40, the shaft from a desired moment the synchronization position 40 or 400 (e.g., the bottom
right point a and point B), can be from O to a or B. O to the meshing process parameter selection
StartMode
StartMode There are three modes available, namely: the shortest distance gradient
(StartMode = 0), a positive gradient (StartMode = 1) and the reverse gradient (= StartMode -1),
the user can select a different mode according to the actual needs of engagement.
