8.7 Synchronous Control Analysis Mode
With synchronous control analysis mode, parameters are only analyzed for
synchronous control when there is a command to start synchronous control. This mode
is used to confirm the synchronous positions of the output axes in order to align axes
with position control before starting synchronous control.
If the target axis bit is ON in [Rq.381] Synchronous analysis request (n) when
starting synchronous control (turning from OFF to ON for [Rq.380] Synchronous
control start (n)), operation enters synchronous control analysis mode.
When the synchronization position analysis is completed, the synchronous control
monitor data ([Md.400] to [Md.402], [Md.406] to [Md.411], [Md.422], [Md.425], [St.420],
[St.421], [St.423], [St.424] (Refer to Section 7.7)) is updated, and the target axis bit in
[Rq.380] Synchronous control start (n) turns OFF to ON.
The [St.380] Synchronous control (n) and start accept flag (M2001+n) is not
turned ON during synchronous control analysis mode.

Start positioning on the [Md.409] Cam axis current
feed value (30n, 30n) at the
beginning after checking of [St.381] Synchronous
analysis complete (n) is OFF.
POINT
(1) Since the synchronous control analysis mode is used for the synchronous
control initial position, a major error (error code: 1769) is not detected.
Therefore, refer to [Md.409] Cam axis current feed value (30n,
30n) that is updated by [St.381] Synchronous analysis complete
(n) OFF to ON, and perform the synchronous alignment.
(2) When [St.381] Synchronous analysis complete (n) is ON at the
synchronous control analysis mode start, [Rq.381] Synchronous control
analysis mode request (n) is turned OFF by turning [Rq.380]
Synchronous control start (n) OFF to ON.
