Controlling Operation and Outputting Data with a Par-
allel Connection
[Image] − [Camera setup] − [] − [Lighting control]
1 Change the setting for lighting control.
When the strobe polarity is set to [Negative], a delay of about 200 to 300 μs occurs from when the TRIG signal is input
until the STGOUT signal goes low. When a high-speed shutter is used, set the [Output polarity] parameter to [Posi-
tive].
• Timing Chart for Strobe Trigger Output Signal
The STGOUT signal turns ON in sync with the trigger input signal from an external device.
Controlling Operation from an External Device
The following Sensor functions can be controlled with command inputs from an external device without
connecting the Touch Finder.
Item Parameter Setting Description
Lighting control Strobe output delay 0 to 65,535 μs
(default: 0 μs)
Enter the delay time from when the TRIG signal is
input until the external lighting is lit.
Strobe output time 0 to 65,535 μs
(default: 1,000 μs)
Set the pulse width of the output signal (STGOUT)
that tells the external lighting when to light.
Operation Description Reference
Switching the scene This command changes the scene when the line process changes. p. 76
Clearing measurement
values
This command clears the measurement values.
The OR signal and D signals are not cleared.
p. 77
Clearing an error This command turns the ERROR signal OFF.
The ERROR indicator is also turned OFF.
p. 78
Re-registering the model
and reference color
This command re-registers the model and reference color. p. 80
Teaching This command uses the image that is currently being input to execute
teaching for all of the registered items.
p. 81
Clearing the OR and D sig-
nals
This command clears the OR signal and D signals. p. 82
Saving data in the Sensor This command saves the current settings (scene data and system data)
in the Sensor.
p. 84
Retrying Inspection by
External
Signal (trigger retry)
This command continues inspection when the trigger signal is ON. p. 85
