Chapter 2 System Configuration and Specifications
Note 1: When the power is turned ON, the RCON system starts up. When field network
communication between the gateway unit and host device is established, the gateway
status signal 0 "RUN" turns ON. After confirming that the "RUN" is ON, begin
communication with the gateway unit.
Note 2: If the gateway unit and driver unit are communicating normally, the gateway status
signal 1 "LNK* (* is axis number)" turns ON.
If a communication error occurs between the gateway unit and driver unit, "LNK*" turns
OFF. However, the ERRT alarm is not generated until the "communication retry count"
set in the gateway parameter configuration tool is exceeded, until which retries are
repeated.
If the communication becomes normal after repeated retries, "LNK*" turns ON.
The signal may also turn ON after temporarily turning OFF due to sudden noise.
Regarding the "communication retry count", refer to "3.9 Gateway Parameter
Configuration Tool / Special parameter setting function descriptions" (page A3-156)".
Note 3: There is no "LNK*" for the EC connection unit.
Note 4: Confirm "RUN" and "LNK*" before inputting "SON". The actuator turns the servo on.
Also for the EC connection unit, there is no "SON". The servo on ELECYLINDER
automatically turns on.
Note 5: When the first "SON" signal is input after power ON, the motor performs excitation
phase detection operation (stepper motor specification) or magnetic pole phase
detection operation (AC servo motor specification).
After confirming that the operation ready signal "SV" (E0RD to E3RD) is ON, input the
travel command or home return command.
Caution
● If the servo is turned ON in the vicinity of the mechanical end, the magnetic pole phase
will not be properly detected, causing abnormal operation, uncertain magnetic pole
error or excitation detection error.
Turn ON the servo in a position away from the mechanical end.
● If the power has been turned OFF, wait 1 second or more before rebooting the power.
Otherwise, the product may malfunction.
