1.2. Terminology
u Classification of Driver Unit [23 type, 25 type, B3 type, etc.]
We classify the Driver Units along the function. They are distinguished by coding. Refer to the
table below for combinations of function and coding.

à Absolute position sensor : Home Return is not necessarily every time when the
power is turned on.
à Incremental position sensor : Home Return is required every time the power is turned
on.
à Basic type : A type of Driver Unit that does not have extended I/O
ports. Parameters set the required I/O signals.
à Extended I/O type : A type of Driver Unit that has extended I/O ports.
You can use multiple functions simultaneously.
This type can be operated by the analog command input.
