(2) I/O signal assignments for each axis
The I/O signals of each axis consist of six input words (channels) and six output words (channels) in the I/O
areas.
z The channels 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 a 2-word (32-bit) binary data (unit: 1 mA).
