Stop causes during axes group operation
The following shows stop causes during axes group operation and the process when each cause occurs.

*1 For each operation of the stop process, refer to the following.
Page 141 Stop processes for axes group
*2 The servo OFF is executed in the driver side and the axis immediately stops, and also the motion side command is stopped.
*3 When the stop cause occurrence axis is immediately stopped by servo OFF, operation differs depending on the setting selected in
AxesGroup.Pr.StopMode_ErrorInGroup. For details, refer to the following.
Page 150 Stop cause occurrence in the configuration axis
*4 If an axes group error (the error that transits the state into the "1: GroupErrorStop" status) occurs in the FB which can be linked by the
buffer mode, automatic deceleration will be performed from the axes group error occurrence.
*5 When Execute of MC_GroupStop is FALSE at stop completion, the axes group status (AxesGroupName.Md.GroupStatus) after stop will
be "4: GroupStandby".
