Cam Toolbox: Function Blocks
MotionWorks IEC61131-3 Toolboxes: 2013-09-13 125
V SensorMaximum LREAL
The latest slave position where
a sensor position is valid for
correction.
LREAL#0.0
(function
block defaults
to
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
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 UDINT Cumulative number of latches missed
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.
B 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 is an adaptation of CamSlave_FeedToLength . The main difference is that this function is
designed for reciprocating slave motion, and uses the Y_CamScale function block instead of the Y_SlaveOffset
function block.
