Synchronizing controller

MG.10.N4.02 - VLT is a registered Danfoss trademark

Application example – Embossing patterns on mould

Moulds of two different kinds and lengths are embossed with a pattern. The conveyor belt operator changes
the position of the pattern by means of two buttons. Each of the two incremental encoders has a zero track
for marker synchronization.
