(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 6 input words (channels) and 6 output words (channels) 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).
