(Note) The areas denoted by Occupied area cannot be used for any other purpose.
Also, exercise caution to avoid node address duplication.
(2) I/O Signal Allocation for each Axis
The I/O signals of each axis consist of one input word (6 words = 12 bytes) and one output word in the I/O
areas.
z
The areas controlled by port number are controlled using ON/OFF bit signals.
z
The current position is a 2-word (32-bit) binary data (unit: 0.01 mm).
z
The command current is expressed using 2-word (32 bits) binary data (Unit: 1mA).
