ProductSize if
left
unconnected.)
V MissedLatchLimit UINT
The number of consecutive
product lengths that can occur
without seeing a mark in the
window. Valid sensor
detections will reset the
internal counter. The next valid
sensor detection will reset the
internal counter.
UINT#0
(interpreted
as infinite)
VAR_OUTPUT
B Valid BOOL
Indicates that the outputs of the function are
valid.
V ActualSize LREAL The actual indexed distance
V LatchPosition LREAL
The slave's position in the CamTable when the
latch occurred
B RecordedPosition LREAL
The slaves latch position as reported by
MC_TouchProbe.
V LimitedPosCorrection BOOL
Indicates that the MaxPosCorrection is limiting the
required correction.
V LimitedNegCorrection BOOL
Indicates that the MaxNegCorrection is limiting
the required correction.
V Adjusting BOOL
Indicates that an adjustment is currently taking
place (Busy output of Y_SlaveOffset)
V MissedLatch BOOL
Indicates that a latch was detected, but it was
outside of the window parameters specified.
B Error BOOL
Set high if error has occurred during the execution
of the function block. This output is cleared when
'Execute' or 'Enable' goes low.
E ErrorID UINT
If Error is true, this output provides the Error ID.
This output is reset when 'Execute' or 'Enable'
goes low.
Notes
•
This function block requires that the ReadAxisParameters function block from the PLCopen toolbox is
also running, preferably in the same task as CamSlaveFeedToLength.
• See the CamSlave_FeedToLength eLearning Module on Yaskawa's YouTube Channel.
Missed Latch Detection feature:
There are two parts to this feature.
