I/O Format
Output Terminals
Terminal
Functions as a BUSY signal. Indicates that the Z500 is performing Trigger measurement. If trigger
DO19
function is set, this terminal can be used to confirm trigger operation.
DO0 Functions as a HIGH terminal for OUT0.
DO1 Functions as a PASS terminal for OUT0.
DO2 Functions as a LOW terminal for OUT0.
DO4 Functions as a HIGH terminal for OUT1.
DO5 Functions as a PASS terminal for OUT1.
DO6 Functions as a LOW terminal for OUT1.
Used to control the timing with which measurement results are obtained by the external device.
GATE Turns ON for a time set so that the external device can obtain the judgment results of the output
numbers for which Hold is set.
DO8 Functions as a HIGH terminal for OUT2.
DO9 Functions as a PASS terminal for OUT2.
DO10 Functions as a LOW terminal for OUT2.
DO12 Functions as a HIGH terminal for OUT3.
DO13 Functions as a PASS terminal for OUT3.
DO14 Functions as a LOW terminal for OUT3.
DO3, DO7
Function as error terminals for OUT0, OUT1, OUT2, and OUT3 respectively.
DO11, DO15
Input terminals
Terminal
TRIGGER Inputs the measurement trigger from a sync sensor such as a photoelectric sensor.

(**) The GATE signal is output only for the terminals of output numbers for which Hold is set.
Ensure that the TRIGGER turns ON while the GATE signal is OFF. If the TRIGGER turns
ON while the GATE signal is ON (including at GATE ON delay), outputs may not operate
properly.
