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.
