Introduction

Synchronisation of the drives via a master angle

3 Introduction

The following subchapters provide information on the electrical shaft.

3.1 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.
