18. Movement by Position Number Specification
Description
Read an external BCD code input as a position number to move the actuator.
How to Use
Use an INB command to read a position number as a BCD code via an input port. A position number
consisting of up to three digits can be specified.

Appendix
19. Movement by External Position Data Input (for Linear Axes)
Description
Receive from the host device an absolute value indicating the position data to be used in the movement,
and move the actuator accordingly.
Example of Use
Use an INB command to read position data as a BCD via an input port. The BCD value to be received has
four digits, with the last digit specifying a decimal place. Axis 1 is moved.
Example: If the value of BCD is “1234,” the axis will move to the position at 123.4 mm.
