7.10 Zone Signal
How the boundaries are set varies depending on the PIO pattern.
x If fixed boundaries are applied to all operations, set them using parameters. (PIO pattern = 0 or 2).
x To set different boundaries for each position number to support multiple loads, set respective settings in the
position table. (PIO pattern = 3)
Example of use in operation) Output a zone signal in a range of 40 to 120 mm while the actuator is moving from the
home to the 150-mm position (position 1).
Method) x PIO pattern = 0 or 2
Use the parameters “Zone boundary+” and “Zone boundary–” to set the zone in
which the zone signal is output, as shown below:
Parameter No. 1 Zone boundary+ 120 (mm)
Parameter No. 2 Zone boundary– 40 (mm)
x PIO pattern = 3
Use the “Zone+” and “Zone-” fields of the position table to set the zone in which
the zone signal is output, as shown below:
No.
