3.2 Virtual master/real master

Virtual master

[3-1] Example "Virtual master" (with master value transmission via digital frequency extension module)

Real master

[3-2] 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.

Slave 1

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.
