Output Terminals
Terminal
RUN Turns ON during Run mode.
BUSY Shows that the F400 is reading an image, changing a scene, etc.
Do not input the next command while the BUSY signal is ON. Otherwise, commands may not be
properly executed.
OR Outputs the overall judgements. (Can be set to turn ON for either OK or NG judgement.)
The overall result will be NG if there is one or more NG judgements for the measurement regions
or output expressions.
DO 0 to Output the judgements for the items allocated to the terminals. (Can be set to turn ON for either
DO 15
OK or NG judgement.)
GATE This signal notifies the external device when the F400 is outputting valid data.
Used to time the reading of the measurement result at the external device.
The time that GATE is turned ON can be set as required for the external device to correctly read
the measurement result.
Make the output time shorter than the duration of the measurement (STEP input interval). If the
cycle is longer, the output timing will fall behind as measurements are repeated.
Input Terminals
Terminal
STEP Inputs a measurement trigger from a photoelectric sensor or other external device.
One measurement will be taken on the rising edge of the STEP signal. Turn ON the STEP for at
least 0.5 ms.
Note When the STEP signal is input while BUSY is ON, the ERR terminal turns ON. Refer
to 5-7 Error Settings .
