"1" is stored when the constant speed status or acceleration status switches to
the deceleration status during position control whose operation pattern is
"Positioning complete".
•
"0" is stored at the next operation start or manual pulse generator operation
enable.
POINT
This parameter is possible to monitor when "
" is valid.
•
This area stores the travel distance during the OPR travel to the zero point that
was executed last time.
For setting units
