Edge-Loss and Line-Loss Detection
4 7 0
Edge-loss and line-loss detection are disabled. This is the default
setting.
4 7 1
Edge-loss and line-loss detection are enabled.
The actuator will stop and the NO FAULT output will
turn off when an
y
active sensor enters the edge-loss or line-loss state. The edge-loss o
r
line-loss state occurs when an edge detector becomes completely
blocked or unblocked, or the digital line guide loses the line or edge it is
following.
Guiding will resume and the NO FAULT output will turn on when al
l
sensors have left the edge-loss or line-loss state.
4 7 2
Line-loss detection is enabled.
When the line guide loses the line, edge detector A will record the
positio
n of the web, the system will switch from Line mode to Edge
A
mode, and edge detector A will then maintain the web at the recorded
position. When the line guide reacquires the line, the system will switch
back to Line mode.
4 7 3
Line-loss detection is enabled.
When the line guide loses the line, edge detector B will record the
positio
n of the web, the system will switch from Line mode to Edge B
mode, and edge detector B will then maintain the web at the recorded
position. When the line guide reacquires the line, the system will switch
back to Line mode.
4 7 4
Line-loss detection is enabled.
When the line guide loses the line, edge detectors A and B
will record
the position of the web, the system will switch from Line mode to
Centerline mode, and edge detectors A and B will then maintain the web
at the recorded position. When the line guide reacquires the line, the
system will switch back to Line mode.
4 7 5
Line-loss detection is enabled.
When the line guide loses the line, the system will switch from Line mode
to Edge A mode, and e
dge detector A will then maintain the web at the
position specified by Offset 2. When the line guide reacquires the line,
the system will switch back to Line mode.
4 7 6
Line-loss detection is enabled.
When the line guide loses the line, the system will switch from Line mode
to Edge B mode,
and edge detector B will then maintain the web at the
position specified by Offset 2. When the line guide reacquires the line,
the system will switch back to Line mode.
4 7 7
Line-loss detection is enabled.
When the line guide loses the line, the system will switch from Line mode
to Centerli
ne mode, and edge detectors A and B will then maintain the
web at the position specified by Offset 2. When the line guide reacquires
the line, the system will switch back to Line mode.
