Explanation
- Acceleration/deceleration type
1. Starting synchronization
When synchronization is started, the workpiece axis speed is
accelerated according to the acceleration rate set in the parameter
(No. 7729).
2. Canceling synchronization
Deceleration starts according to the acceleration rate set in the
parameter (No. 7729).
- Acceleration/deceleration and automatic phase synchronization
1. Starting synchronization
When synchronization starts, the travel speed of the workpiece
increases by the acceleration specified in parameter 7729.
Once the synchronization speed is attained, phase synchronization
is performed automatically. In phase synchronization, the
workpiece axis is moved so that the workpiece axis position at the
time of synchronization start command issue matches the one-
rotation signal position of the spindle.
