Change Condition [394]
This parameter determines the criteria for changing the
master. This menu only appears if Alternating MASTER
operation is selected. The elapsed run time of each drive is
monitored. The elapsed run time always determines which
drive will be the 'new' master drive.
This function is only active if the parameter “Select Drive
[393]”= “All” is used.

Change Timer [395]
When the time set here is elapsed, the master drive will be
changed. This function is only active if “Select Drive

as smooth as possible. The maximum number to be
programmed in this menu depends on the number of
additional drives.

If the number of drives is set to 6, the maximum value will
be 4. This function is only active if “Select Drive [393]”=All.
