(2) I/O signal assignments for each axis
An I/O signal of each axis consists of 8 bytes of I/O addresses.
z Control signals and status signals are bit ON/OFF signals.
z The target position and current position are both 4 bytes (32-bit) binary data. Although values from -999999 to
+999999 (unit: 0.01 mm) can be handled by the PLC, set position data within the software stroke range (0 up
to the effective stroke length) of the applicable actuator.
z The specified position number and completed position number are both 2 bytes (16-bit) binary data. Although
values from 0 to 767 can be handled by the PLC, use the PC software or teaching pendant to specify a
position number for which operation conditions are already set.
