SYNC command
(Waiting for trail sync)
This function can be used like the link mechanism of a machine.
The slave axis synchronizes with the master axis following the specified accel-
eration, constant speed, and deceleration areas.
(In the diagram below, vertical and horizontal axes indicate speed and time
respectively.)
Acceleration Constant speed

master ax-
is is accel-
erated
Trailing is started when the slave axis is standing by and the marker sensor is
turned ON. Once it catches up with the master axis, synchronous operation is
initiated.
