U600*
S.RecomV Sync
2600
The parameter defines the connector from which the
master setpoint for synchronism is to be read. Three
sources can be indicated which can be changed over via
parameter U606.
Function diagram [834.1]
The following sources are practical as input connectors:
1.) Use of the virtual master axis
The virtual master axis (output connector KK817) is
connected to the synchronism via the SIMOLINK receive
buffer, e.g. connector KK7031.
Thus no dead time differences occur between the drives
connected at the virtual master axis.
Example:
P751.01=817
P751.02=817
==> The output of the virtual master axis [832.8]
is connected to transmit word 1 and 2 of the
SIMOLINK [160].
U600.01=7031
==> This signal is collected from the receive double
word 1
of the SIMOLINK [150] and taken to the input of
synchronism [834]. This interconnection is also
practical
with the MASTERDRIVES unit on which the virtual
master
axis is computed in order to keep the dead time
differences
between the drives at an optimal minimum.
2.) Use of a real master externally
In this case, the position actual value of another unit is
transferred via SIMOLINK to synchronism. During the
transfer, a dead time occurs which results in an angular
error.
3.) Use of a real master internally
With the internal master, the encoder of the master drive
is also applied with the slave drive (without using
SIMOLINK) and the master position is determined via a
dedicated encoder evaluation.
In this case, no dead time occurs between the master and
the slave drive.
