APR Scenarios
Table 59 on page 265 provides detailed information on when the APR feature
recovers absolute position. The following assumptions must be considered. In
each of these cases, the APR feature restores absolute position and preserves the
state of the Axis Homed bit. This feature indicates that the axis has a machine
referenced absolute position.
• All relevant axes are integrated motion axes.
• Yes, indicates that machine reference is recovered (for Axes that have
been homed).
• No, indicates that machine reference is not recovered (for Axes that have
been homed).
ATTENTION: Whenever memory becomes corrupt, you lose position even if
you have it stored on a memory card.
