Gocator Line Profile Sensors: User Manual
Gocator Web Interface • 136
Variable Length: The sensor
generates surfaces of variable
length. Profiles collected while the
external digital input is held high are
combined to form a surface. If the
value of the Max Length setting is
reached while external input is still
high, the next surface starts
immediately with the next profile.
This mode is typically used in robot-
mounted applications, for example,
measuring different parts on an
engine block.
For correct length measurement,
you should ensure that motion is
calibrated (i.e., encoder resolution
for encoder triggers or travel speed
for time triggers).
For more information on
connecting external input to a
Gocator sensor, see Digital Input on
page 621.
You can optionally enable part
detection to process the surface
after it has been generated, but the
generation itself does not depend
on the detection logic. To do this,
check Enabled in the Part
Detection panel.
Rotational: The sensor reorders
profiles within a surface to be
aligned with the encoder’s index
pulse. That is, regardless of the
radial position the sensor is started
at, the generated surface always
starts at the position of the index
pulse. If the index pulse is not
detected and the rotation
circumference is met, the surface is
dropped and the Encoder Index
Drop indicator will be
incremented.This mode is typically
used in applications where
measurements of circular objects or
shafts need to be taken, such as tire
