12.1.2 Virtual master/real master
Virtual master
[12-1] Example "Virtual master" (with master value transmission via digital frequency extension module)
Real master
[12-2] Example "Real master" (with master value transmission via digital frequency extension module)
r In an interconnection, a drive takes
over the task of the (virtual) master
and is the first slave drive at the same
time.
r The master value created in the TA by
the "Virtual master" function is
transmitted via a bus system or the
digital frequency output to the other
slave drives.

r The master value for a slave drive can
be also specified by a real master (e.g.
external encoder).
r The master value can be specified e.g.
via the digital frequency input of the
master frequency extension module or
a bus system.
r The master value (possibly conditioned
in the TA) by the "Virtual master"
function is transmitted via a bus
system or the digital frequency output
to the other slave drives.
