MC_GearInSuperImposed - Example of "Superimposition"
The signal profile in the example below demonstrates the differences between
absolute base synchronism and absolute superimposing synchronism.
Phase one - Base synchronism
Exe_1 starts absolute base synchronism. The following axis (Axis_3) changes to
synchronized operation after a short delay time has expired, and the technology
function reports InGear_1.
Within the basic synchronization phase, the position of the basic motion
corresponds with the position of the additive motion, because the position of the
superimposing motion starts at 0 by default.
An absolute reference is established between the master position (Axis_1) and the
position of the basic motion (green signal profile.)
Phase two - Base synchronism and superimposing synchronism
Exe_2 starts absolute superimposing synchronism (orange-colored signal profile.)
An absolute reference is established between the master position (Axis_2) and the
superimposing motion of the following axis. The absolute reference between the
master position (Axis_1) and the position of the basic motion (green signal profile)
is retained.
The following axis position (Axis_3) is derived from the sum of the "position of
basic motion" plus "position of superimposing motion" values. When superimposed
synchronism is reached, the technology function reports InGear_2.
