(2) I/O Signal Allocation for each Axis
The I/O signals for each axis consists of 4 words for each I/O bit register.
z
The control signals and status signals are ON/OFF signals in units of bit.
z
The target position and current position are expressed using 2-word (32 bits) binary data. The
figures from –999999 to +999999 (Unit: 0.01mm) can be set in PLC. However, set the position data
within the soft stroke range (0 to effective stroke length) for the actuator in question.
z
The specified position No. and completed position No. are expressed using 1-word (16 bits) binary
data. The figures from 0 to 767 can be set in PLC. However, set the position No. for which the
operation conditions have been set in advance using the teaching tool such as the PC software.
PLC Output
Address (* “n” shows the head register address per each axis).
