Chapter 2 System Configuration and Specifications
(2) Number of Connectable Units of Driver Unit and EC Connection Unit
Up to 16 axes
(Note 1)
can be controlled with each gateway unit.
In the perspective of the unit structure, there is no upper limit to the number of connectable.
Keep it at 16 axes at minimum for the driver unit and EC extension unit. If 17 or more actuators
are to be controlled, use a configuration of 2 or more gateway units.
The EC connection unit can be connected for four units at maximum, however, it cannot be
connected if the top axis number exceeds 0 to 15. (The axes numbers for the EC connection unit
should be assigned from the back of those in the driver unit and the SCON extension unit.)
No matter if ELECYLINDER is connected or not, the EC connection unit occupies domains and
axes numbers for four axes by one unit.
Note 1: When direct numerical control mode is used with field networks other than CC-Link or
CC-Link IE Field, up to 8 axes can be connected.
