Absolute Mode
When the cam shaft position relationship MasterAbsolute parameter is TRUE, the
position of the spindle shaft between the cam phase and its absolute relationship, at any time,
the cam phase of the spindle is equal to the time the main shaft spindle maximum range value
The result of the modulo operation. For example: spindle absolute mode, the cam spindle
relationship is the maximum range 360, the axis position of the main shaft 100, a cam phase
which is 100 (= 100% 100 360); the position of the shaft 500 of the main shaft, which cam a
phase of 140 (= 500% 140 360), and so the relationship between the spindle axis position
with its cam phase as shown.
When SlaveAbsolute parameter is TRUE, the position of the shaft between the shaft and
its absolute cam phase relationship, at any time, from the phase of the cam shaft is equal to
the time to make the position of the cam shaft from a relationship between the shaft axis from
a maximum range value modulo result of the operation. When the absolute mode Slave axis,
consistent with the correspondence relationship between the phase of its spindle axis position
and its cam.

Scaling and position misalignment (Offset and Scaling)
From the relationship between the main axis of the cam advance planning, but the
implementation of the cam, the position shift may be pre-planned based on a cam relationship
