4.8.4 Target window
The target window monitors the current position after completion of a positioning
operation. A positioning operation is complete as soon as the current position is in
the target window. Via parameter
Target Window 1165, you can define as from
which distance from the target position the signal "60 – Target Position Reached" is
set. This setting is valid both for the positive and negative direction.
If the parameter value is set to 0, the operation will be complete as soon as the
target position is reached.
Via parameter
Target Window Time 1166, you can define how long the axis must
be in the target window before "60 – Target Position Reached" is signaled.

Note: The size of the target window affects the automatic sequence of motion
blocks because the positioning operation requires a higher precision in
the case of a small target window (small tolerance). The following mo-
tion block is started when the target window is reached.
