3.4.9 About Commands (Position Data Read/Write and Alarm Axis Read)
By sending a specific code to a specific address, the position data reading and writing, and the
reading of the axis number that an alarm was issued and the alarm code can be performed.
(Note) It is not necessary to use commands in Simple Indication Mode because no position
data is to be used in it.
Caution:
• The command cannot be used in MECHATROLINK.
• It is not necessary to use commands in Simple Direct Mode because no position data is to
be used in it.
Shown below is the table to indicate the assignment of each signal.
