Teaching - Panasonic LightPix AE20 User Manual

5.2.4 Teaching

The LightPixAE20 can execute a teaching using the signals from the external devices based on the currently
captured image, but exposure time and binary level may be changed after teaching execution. Therefore,
execute a teaching only if there is no problem having these values changed.
Timing chart: Teaching for OK product only
1. Make sure the READY signal is ON and inptu the TEACH signal.
2. Input a product type, for which you want to peform a teaching, to the ports of TYPE 1-3 in more
than two milliseconds (T1).
3. After two milliseconds (T2), input the TRIGGER signal.
Input the TRIGGER signal for the following time period.
Used inspection application
Color Area, Color Judgement, Color
Pattern Matching
Edge detection, Peak, Measurement
The READY signal is turned off and a teaching is executed. ("ADJ" is displayed on the operation unit.)
After the teaching is completed, the READY signal is turned on. If the unit failed to complete the teaching, the
ALARM signal is turned on.
4. Turn the TEACH signal off and switch to INSPECTION (RUN, RUN VIEW) mode.
When the ALARM signal is turned on at the previous step, it keeps on until the teaching is successfully complete.
If the ALARM signal is output after teaching, adjust exposure time and binary level using the operation
unit or AETOOL. As long as the unit keeps outputting the ALARM signal, it cannot execute an inspection
properly.
