Absolute Position Recovery Scenarios
This table provides detailed information on when the APR feature recovers
absolute position. The following assumptions need to be considered. In each of
these cases, the APR feature restores absolute position and preserves the state of
the Axis Homed bit, indicating that the axis has a machine referenced absolute
position:
• All relevant axes are CIP 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 an SD card.
