Timing charts
The following shows the timing charts when communication is performed with external devices.
Measurement
Continuous measurement
Measurement is performed continuously for the duration that the TRIG signal is ON.
The measurement result is updated, and output to external devices at each measurement cycle.
Synchronous measurement
Measurement is performed only once in synchronous with the change
in TRIG signal state from OFF to ON, and the result is output.
• The minimum ON width of the TRIG signal is 1 ms.
• The OUTPUT signal is held until the next measurement result is updated.
Note, however, that when one-shot output is currently set, the OUTPUT signal is held for the preset time.
Teaching
Workpiece stop teaching
Teaching processing is performed according to TRIG signal input after the TEACH signal is input from the outside.
Measurement is not performed while teaching is being performed. Do not move the workpiece until teaching is completed.
1. Turn the TEACH signal ON.
2. Confirm that the ENABLE signal has turned OFF.
3. Make sure that the workpiece to be taught is in the teaching area.
4. Input the TRIG signal from the outside.
5. The ENABLE signal turns ON after teaching is completed. At this timing, check the state of the ERROR signal.
6. When teaching has been completed successfully, the ERROR signal stays OFF.
7. When teaching fails, the ERROR signal turns ON.
8. Turn the TEACH signal OFF, and end teaching processing.
When teaching fails, the state before teaching was initiated is returned to. Perform teaching again.
If the TEACH signal is turned OFF midway, teaching is disabled.
