Packet R-QUE OV
Packet S-QUE OV These messages indicate an error in the serial communication with the controller.
Cause: [1] Garbage data due to the effect of noise
[2] Duplicate slave numbers when multiple controllers are controlled by
serial communication
Action: [1] Adjust the wiring in a manner eliminating the effect of noise and
review the installation of equipment, etc.
[2] Change the slave numbers to avoid duplication.
If the message is still displayed after taking the above actions, please contact IAI.
307 Memory command refused This message indicates that the command was refused in the serial communication
with the controller.
309 Write address error This message indicates that an indeterminate WRITE address error occurred in the
serial communication with the controller.
These conditions do not occur in normal operation. Should they occur, record the
entire error list before cutting off the power for use in the cause investigation.
Also contact IAI.
30C No connected axis This message indicates that no actuator address is recognized.
Cause: [1] The controller is not operating properly.
[2] Only the supplied communication cable (SGA/SGB) is disconnected.
[3] If a SIO converter or insulated PIO terminal block is used, 24V is
supplied to the converter but the link cable is not connected.
[4] The ADRS switch settings are duplicated by mistake when multiple
actuators are linked.
[5] Faulty communication IC on the control board
Action: [1] Check if the LED is illuminating in green.
If the LED is not illuminating, the controller board is faulty.
[2] If a spare teaching pendant is available, replace the current pendant
with the spare unit, or with a PC, and see if the message disappears.
[3] Connect the communication cable and then supply 24-V power.
[4] Make sure the address settings are not duplicated.
If a green LED lamp is lit and none of causes [2], [3] and [4] is present, please
contact IAI.
