5.3.3 Assignment for Each Axis
The I/O signals of each axis vary in terms of the size and content of each applicable area depending
on whether the axis is a positioner operation axis or simple direct operation axis.
(1) Control/status signals for positioner operation axis
Each axis consists of two PLC output (control signal) bytes and two PLC input (status signal) bytes,
as shown below. Five patterns are available depending on the PIO pattern set by the gateway control
signal PPS.
* Byte address A: Gateway head address + 18 + 2n
n: Axis number assigned to a positioner operation axis (0 or greater)
