Parameter Trigger Source Description
This setting is not displayed when Surface Generation is set
to Fixed Length, Variable Length, or Rotational (Surface
Generation on page 149).
See Digital Input on page 769 for more information on
connecting external input to Gocator sensors.
Behavior Encoder Specifies how the Gocator sensor is triggered when the target
moves. Can be Track Backward, Ignore Backward, or Bi-
Directional. See Triggers on page 117 for more information on
these behaviors.
Spacing Encoder, External Input Specifies the distance between triggers (mm). Internally the
Gocator sensor rounds the spacing to a multiple of the encoder
resolution.
Reversal Distance Encoder
When encoder triggering is set to Bi-Directional, use this
setting to ignore jitter or vibrations in your transport system by
specifying what distance the target must travel before a
direction change is triggered. One of the following:
Auto: The distance is automatically set by multiplying the value
in Spacing by 3.
Custom:Set the distance (in millimeters). Various functions in
the sensor depend on this value to explicitly determine the
point where direction change is triggered. Set this value larger
than the maximum vibrations you see in your transport
system.
Units External Input, Software Specifies whether the trigger delay, output delay, and output
scheduled command operate in the time or the encoder
domain.
The unit is implicitly set to microseconds with Time trigger
source. The unit is implicitly set to millimeters with Encoder
trigger source.
Trigger Delay External Input
Controls the amount of time or the distance the sensor waits
before producing a frame after the external input is activated.
This is used to compensate for the positional difference
between the source of the external input trigger (e.g.,
photocells) and the sensor.
Trigger delay is only supported in single exposure mode; for
details, see Exposure on page 129.
Depending on the surface generation settings, some trigger options may not be available.
