Input/Output Timing; Performing A Reading Operation (Internal Trigger: Off) - Panasonic LightPix AE20 User Manual

5.2 Input/Output Timing

5.2.1 Performing a Reading Operation (Internal Trigger: OFF)

When you perform inspection by inputting the TRIGGER signal from external devices, follow the timing chart
shown below. If you switch product types before executing an inspection, input the signals following the timing
chart below.
1. Make sure the READY signal is ON, and then inptut TYPE 1-3 singnals.
The signal is changed to the product type you set. Input signals for product switch within more than two
milliseconds before the signal for inspection execution (trigger) signal is input (T1≧2 ms).
2. Make sure the READY signal is ON and input the TRIGGER signal for more than T2 time.
It may take approximately max. 750ms to change or read data through RS-232C communication using external
devices or to establish USB communication (AETOOL).
When the READY signal is off, the LightPixAE20 begins a reading operation.
If capture delay time (CAP.D) has been set, images are captured in the setting time after TRIGGER signal
recognition.
When the product types are switched, the first reading time (T3) becomes 50ms longer than the second or later
reading time.
3. The LightPix output the inspection results to the ports of OUT1 to OUT3. The READY signal is
turned ON.
If the Output Delay time (OUT.D) is set, inspection results are output to the ports of OUT1 to OUT3 in
the set time after inspection completion, at the same time, the REDY signal is turned ON.
•
Inspection time differs depending on the application and inspection condition. Refer to page 31.
•
Refer to the pages describing CONFIGURATION mode for each inspection application for details
of current values of Capture Delay (CAP.D), Output Delay (OUT.D).
