8.1.2 Limit switch output function
[Control Details]
(1) The limit switch function outputs the ON/OFF pattern from the A1SY42/ AY42
at the set addresses.
Before running the limit switch output function, the ON/OFF point addresses
and the ON/OFF pattern must be set from a peripheral device.
(Settings cannot be made by the sequence program.)
The number of limit switch outputs per axis and the ON/OFF points are as
follows:
(a) Number of limit switch output points .............8 points/axis,
total 256 points
(b) ON/OFF points...............................................10 points/axis
Set an address in the stroke limit
range for each point.
