6.4 Additional program organisation units
6.4.1 SMC_GetCamSlaveSetPosition
This program organisation unit calculates the current set position of an axis (slave), if this
axis is coupled to the motion of a different (master) axis via a cam. However, neither axis
is moved or affected by this.
This program organisation unit is used if a slave axis is to be moved to the set position
resulting from a cam prior to being connected to that cam.
The program organisation unit calculates the corresponding value within a cycle, so no
Done output is required.
