Prevention
The master axis continued to move in
the direction opposite to the sync
direction of the master and slave
axes, resulting in an overflow.
Correct the program so that the move-
ment direction and travel distance of
the master axis are in the sync direc-
tion after the start of synchronization.
Write the program so that the move-
ment direction and travel distance of
the master axis is the sync direction
after the start of synchronization.
