2.4.2 Synchronized Electronic CAM Operation
A slave axis operates according to the CAM tables while synchronizing to the specified master axis.
(1) Synchronous movement type
It is possible to select either “immediate start” or “start at master axis arriving at specified position” as
synchronous start type. The setting is made using the XCAS (expansion motion board axis
synchronization electronic CAM (master axis specification) synchronization start) command.
[1] Immediate start
Start synchronization by setting the current master axis position as the base point (phase = 0).
[2] Start at master axis arriving at specified position
Start synchronization from the time when the master axis arrives at the specified position, by
setting the position as the base point (phase = 0).
