(Note) The [occupied area] cannot be used for any other purpose.
Also pay attention to use of duplicate addresses.
(2) I/O signal assignments for each axis
An I/O signal of each axis consists of 6 words (12 bytes) of I/O addresses.
z Addresses controlled by port numbers are controlled by bit ON/OFF signals.
z The current position is a 2-word (32-bit) binary data (unit: 0.01 mm).
z The command current is a 2-word (32-bit) binary data (unit: 1 mA).
