(2) I/O Signal Allocation for each Axis
The I/O signals of each axis consist of one input word (4 words = 8 bytes) and one output word in the I/O
areas.
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 concerned.
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 tools such as PC software.
