32. Devices working with the encoder
. As the encoder is rotating the object on
the conveyor belt moves.
. Signal output called A, B, Z phase is
manufactured as the encoder rotates.
. The signals on A,B,Z phase are
transmitted to the frame grabber through
the cables
. The frame grabber receives the
signals(A,B,Z phase) and CC signal is
generated accordingly.
. Camera receives CC signal and capture
line.
