7.3.3 Virtual master
The technology applicaon allows operaon with a virtual master. In this case, a drive in the
ne
twork takes on the role of the virtual master while at the same me serving as the rst
slave drive. The generated master value is transmied to the slave drives via the system bus.
Modes of operaon
The virtual master oers the following operang modes:
