Timing chart: Teaching for OK and NG products
If the TEACH function is set to OKNG in CONFIGURATION mode, execute a teaching following the
instructions below:
1. Confirm that the READY signal is ON and inptut 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. Capture the OK product and input the TRIGGER signal after two milliseconds (T2).
The READY signal is turned off and the unit starts a teaching for OK product. ("ADJ" is displayed on the operation
unit.)
Input the TRIGGER signal for the following period of time.
Used inspection application
Color Area, Color Judgement, Color Pattern Matching
Edge Detection, Peak, Measurement
4. After capturing the NG product, confirm that the READY signal is ON and then input the
TRIGGER signal.
(Time period of T3 is the same as that used for step 3. )
After the READY signal is turned off, the unit executes a teaching for NG product.
When the teaching was completed, the READY signal is turned on.
If the unit failed to complete a teaching, the ALARM signal is turned on.
5. Turn the TEACH signal off and switch to INSPECTION (RUN, RUN VIEW) mode.
If the ALARM signal is turned on at the previous step, this ALARM signal is held on until the unit successfully
completes a teaching.
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.
