Caution when Connecting EC Connection Unit
Described below is the caution notes when the gateway unit and the EC connection unit are
connected.
● The EC connection unit occupies domains for four axes (one word) even though not all of four
axes are connected. Also, an axis number that an axis is not connected should not be pulled
one number forward.
● The axis numbers for the EC connection unit should be assigned from after axes connected to
driver units (RCON-PC/AC/DC/PC/SC) and SCON extension unit.
● 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 and an alarm should get generated.
● When the EC connection unit is connected, the initialization time should be longer compared to
when only the driver unit is connected (by approx. 60msec).
● For the structure with driver units and EC connection units existing together, communication
from a teaching tool to EC connection units and ELECYLINDER will not start unless the
initialization communication to all the units has finished.
[Initializing Communication when EC Connection Unit Existed Together]
● Time taken for the movement command (ST* Signal) reaching from PLC to ELECYLINDER
should be approximately 20msec.
● When the EC connection unit is connected, the time taken for data update for the PC software
should be longer compared to when only the driver unit is connected in the structure.
(1) Finish initializing communication with driver units and SCON-CB
conducted first
(2) Initializing communication for EC connection units starts
When communication of (1) failed and did not finish in normal condition,
communication in (2) would not start.
Without completing communications in (1) and (2),
(3) communication from teaching tool to EC connection unit and
ELECYLIDER should not be conducted.
* Communication from teaching tool to gateway unit should be available.
