12.1 Introduction
The following subchapters provide information on the electrical shaft.
12.1.1 Synchronisation of the drives via a master angle
By coupling the drives via a master angle the positions are firmly allocated to each other
like a mechanical shaft.
r A drive with a virtual master or a real master (encoder) is able to create the master
angle and transmit this to the other drives which follow this master angle.
Advantages of this type of synchronisation
r The communication between the drives is very simple. A time-consuming evaluation of
the status signals of each drive and the control signals to be generated from it for each
single drive is not required.
r Due to the flexible electronics trimming functions can be carried out very easily. Thus,
motion sequences in machines can be easily synchronised and optimised.
r A variation of the master angle speed changes the number of cycles of the machine.
The drives keep the position allocation.
