The CAM SHIFT function can operate in two modes. The adjustment can take place over
a time specified in milliseconds, or over a relative change in position of the master. Oper-
ation is changed by setting sCamShift_Mode to either zero or one. Zero is the time-based
setting, and one is the position-based setting. The position setting is more practical,
because the time to complete the shift will vary as the machine speed varies. It is easy to
control the corrections and be sure they are complete when the master reaches a certain
position. If the master stops, the correction waits partially corrected.
