Packet R-QUE OV
Packet S-QUE OV An error occurred in serial communication with the controller.
Cause:
[1] Garbage data due to noise
[2] Duplicate slave numbers when multiple actuators are controlled via
serial communication
Action: [1] Revise the wiring, equipment layout, etc., to eliminate noise.
[2] Change the slave numbers to eliminate duplication.
If the message persists, please contact IAI.
307 Memory command denied A command was denied in serial communication with the controller.
309 Write address error An indeterminable write address error occurred in serial communication with the
controller.
These messages do not generate during normal operation. Should either of them
occur, record the entire error list before turning off the power. The recorded error
list will help us identify the cause of the problem.
Also contact IAI.
30C No connected axis The controller axis number cannot be recognized.
Cause:
[1] The controller is not operating properly.
[2] Only the communication line of the supplied cable (SGA/SGB) is
open.
[3] If the SIO converter is used, the link cable is not connected although
the converter is receiving 24 V.
[4] When multiple controllers are linked, the ADRS switch is set to the
same number by mistake on two or more controllers.
Action: [1] Check if the RDY LED on the controller is lit. If this LED is not lit, the
controller is faulty.
[2] If you have a spare teaching pendant, change to the spare teaching
pendant. Or, switch to the PC software mode and see if the message
will disappear.
[3] Connect all pairs of converter and controller using link cables, and
then supply the power.
[4] Set each ADRS switch to a unique number.
If the message persists, please contact IAI.
