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.
