Position reference
The desynchronization mode is set in the "Position reference" drop-down list:
Setting Meaning
Stop at desynchronization
position
Starts desynchronization at the desynchronization position.
The desynchronization length is derived from dynamic data for a time-
based synchronization profile, and from the "Desynchronization length"
parameter for a leading axis-specific synchronization profile.
Desynchronization starts after this length has been passed.
Stop before desynchronization
position
In this mode, desynchronization starts when the axis reaches the
Desynchronization position.
The position at which the desynchronization motion is started is
determined by the dynamic data when operating with time-based
synchronization profile, and by the "Desynchronization length"
parameter when operating with leading axis-specific synchronization
profile.
Stop symmetrically to
desynchronization position
In this mode, desynchronization starts when the axis reaches the
middle of the desynchronization length. The desynchronization motion
starts before the axis reaches the desynchronization position and ends
when it overtravels this position.
Desynchronization starts based on the profile, with reference to the
desynchronization length or dynamic settings.

4.6.6 Monitoring functions
The slave values and compensation at the following axis calculated at the
synchronization object are monitored, with respect to the dynamic response of the
following axis. Compensating motions will be generated accordingly.
The current maximum limits for velocity and acceleration (and jerk) on the axis
influence this monitoring process.
If a motion can not be carried out, an attempt is made to follow the values as
closely as possible with a compensatory motion specified by the maximum
dynamic response values of the axis. The result is a setpoint error.
