Timing Chart
Output Terminals
Terminal
RUN Turns ON during RUN mode.
BUSY Shows that the V530-R150 is reading an image, changing settings, etc.
Do not input the next command while the BUSY signal is ON.
Otherwise, commands may not be properly executed.
OK/NG Outputs the judgment under the set reading conditions.
(Can be set to turn ON for either OK or NG judgment.)
GATE Used to control the timing with which the reading judgment is read at the
external device.
The duration for which the GATE terminal is turned ON can be set as
required for the external device to correctly read the reading judgment.
Make the output cycle shorter than the duration of the reading (TRIG A
input).
If the cycle is longer, the output timing falls behind as readings are
repeated.
Gate ON delay, Gate ON time and Output period are set under the set
communications conditions.
Input Terminals
Terminal
TRIG A Inputs a reading trigger from a photoelectric sensor or other external
device.
One reading is taken on the rising edge of the TRIG A signal.
Turn ON for at least 0.5ms. The duration of TRIG A signal input depends
on reading time. While reading is being performed, BUSY terminal turns
ON and does not accept input signals. Refer to 3-4 System Examination
for the standard reading time.
