(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 personal computer software or teaching
pendant.
