Example application for an FM450-1
Here a specific number of parts is to be filled into a box. An FM 450-1 counter assumes the
job of counting the parts and controlling the two motors for transporting the parts and the
box.
If the box is in the right position, belt A is stopped via the light barrier, the counting process is
started and the motor for belt B switched on. If the programmed number of parts are in the
box, the FM 450-1 stops the motor for belt B and switches on the motor for belt A so that the
box can be transported away. The counting process can start again when the next box
reaches the light barrier
