Positioning Completed Flags
A Positioning Completed Flag will turn ON when the axis reaches its target
position in a positioning operation and the axis is within the in-position range
specified in the system parameters.
Once the axis enters the in-position range of the target position and the Posi-
tioning Completed Flag is turned ON, the flag will remain ON until the next
positioning operation is performed, even if the axis leaves the in-position
range.
The Positioning Completed Flag will turn ON if the positioning operation is
interrupted before the target position is reached but the axis is within the in-
position range.
In-position checks are performed during MPG/sync encoder operation and the
flag will turn ON when the axis is within the in-position range.
When a positioning operation is started, the Positioning Completed Flag will
be turned OFF at the same time that the Axis Operating Flag is turned ON.
Use the Positioning Completed Flag as a condition to check when the target
position has been reached and the next command can be executed.
