Details of setting items
■MasterOffset (Master axis offset)
The phase of the master axis can be shifted for the amount of offset by setting MasterOffset. (This does not affect
MasterStartDistance or MasterSyncPosition.)
When other than "0" is set at operation start, the phase of master axis is changed to the cam position per cycle which is added
the amount of offset for position of the Master at rising edge of InSync. The operation is the same as when changing while
InSync is TRUE.
■SlaveOffset (Slave axis offset)
The displacement of the Slave is shifted for amount of offset.
When other than "0" is set before starting up InSync, the command which is added the position of Slave for the amount of
offset at rising edge of InSync is output. The operation is the same as when InSync is changed during TRUE.
■MasterScaling (Master axis scaling)
Expand/reduce the cam length per cycle of the cam table.
When changing during synchronization, a command for the moving amount is output to adjust the position of Slave to the
position of the cam table.
■SlaveScaling (Slave axis scaling)
Expand/reduce the cam stroke amount of the cam table.
When changing during synchronization, a command for the moving amount is output to adjust the position of Slave to the
position of the cam table.

■MasterStartDistance (Master axis follow-up distance)
Set the position of Master where Slave starts the cam operation. StartMode causes the following specification. When passing
the point shown below, InSync turns TRUE and the slave axis starts operation.
StartMode
1: mcAbsolute
2: mcRelative
This setting is not used when "0: mcImmediate" is set to StartMode.
