Change the setting for lighting control.
Item Parameter
Strobe output delay 0 to 65,535 μs
Lighting control
Strobe output time
Important
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.

Description
This command changes the scene when the line process changes.
This command clears the measurement values.
The OR signal and D signals are not cleared.
This command turns the ERROR signal OFF.
The ERROR indicator is also turned OFF.
This command re-registers the model and reference color.
This command uses the image that is currently being input to execute
teaching for all of the registered items.
This command clears the OR signal and D signals.
in the Sensor.
This command continues inspection when the trigger signal is ON.
Controlling Operation and Outputting Data with a Parallel Interface Sensor Data Unit
Description
Enter the delay time from when the TRIG signal is
input until the external lighting is lit.
Set the pulse width of the output signal (STGOUT)
that tells the external lighting when to light.
