4.8 Using the "Virtual master" function
Instead of a real master, you can also use a "virtual master" for operating the electronic
gearbox. In this case, one drive in the network acts both as a (virtual) master and the first
slave drive. The master value generated by the "Virtual master" function in the TA is
transferred to the other slave drives via the digital frequency output:
