3.9.5 Relative synchronism with mark synchronisation and virtual master

[3-7] Relative synchronism with virtual master (rail)

In case of the relative synchronism with mark synchronisation, there is a position reference

between tool and web, which occurs in each register. For this, a slight correction is

superimposed to the synchronous motion with regard to the web. Such applications are,

for instance, printing machines.

For the mark synchronisation in particular the register r (the cycle of the guiding angle)

and the distance of the sensor

s from the home position of the tool (distances a

and a

)

are relevant.

n Virtual master (and slave 1)

o Slave 2

p Slave 3

q Electrical shaft, implemented here via system bus (CAN).

r Register (cycle of guiding angle/guiding angle)
