Synchronous Control Analysis Mode

With synchronous control analysis mode, advanced synchronous control parameters are only analyzed 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 "[Cd.381] Synchronous control analysis mode" when starting synchronous control (turning the
target axis bit from OFF to ON for "[Cd.380] Synchronous control start"), operation enters synchronous control analysis mode.
When the synchronization position analysis is completed, the synchronous control monitor data ([Md.400] to [Md.425]) is
updated, and the target axis bit in "[Cd.380] Synchronous control start" turns OFF.
The busy signal is not turned ON during synchronous control analysis mode.
When starting synchronous control with synchronous control analysis mode, the following error does not occur.
• Cam axis command position value restoration disable (error code: 1C29H)
