Synchronous Control Analysis Mode - Mitsubishi Electric QD77MS User Manual

5.4 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 "[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.
