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 controller 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 is used, 24 V is supplied to the converter but
the link cable is not connected.
[4] Duplicate slave numbers in a configuration where multiple
controllers are linked.
Action: [1] Check if the RDY LED on the controller is lit. If this LED is unlit,
the controller 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 link cable between the converter and controller first,
and then supply the power.
[4] Eliminate duplication among slave numbers.
If the message is still displayed after taking the above actions, please
contact IAI.
