Caution: If “start at master axis arriving at specified position” is specified, synchronization is not
started unless the master axis arrives at the specified position.
If the encoder resolution of the master axis is low, even when the position is moved toward
the specified position as the target, a master axis may not be able to arrive at the specified
position.
Please be careful when you create applications that move the master axis position slightly
past the synchronization start specification position to start synchronization and then move
it to the opposite direction.
