During production the machine slows down and the synchronisation between downstacker and pusher is lost

Possible cause:

The encoder signal for the production speed of the inverter U7 is coming from a external encoder mounted on the downstacker. On the shaft of this encoder there is a small white plastic gear wheel mounted. Please check the screw of this wheel, it might not be fixed well.

> See picture below to find the encoder.
