SYNCMODE (Operation mode synchronous run)

Command
SYNCMODE
With this command the behavior of synchronization controller be selected
MS: Master Slave Control. Axis 2 is always the Slave
AV: Average value control

Picture 1: Control structure of the average value controller
Both actual positions are checked. The calculated average value serves as command value for the synchro-
nous controller, which has an effect on both axes while trying to synchronize them. The lagging one will be
accelerated and the advanced one decelerated.

Picture 2: Control structure of the master / slave principle
The actual position of the master axis serves as command position for the synchronous controller. It exerts
influence on the slave axis and tries to synchronize it to the master axis. Here, the parameterization should
be adapted in a way that the master axis is speed – limited. Otherwise a lagging slave axis may not be able
to compensate the synchronous error.
