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.

30C No connected axis This message indicates that no controller axis number is recognized.
Cause: [1] The controller is not operating properly.
[2] Only the supplied communication cable (SGA/SGB) is
disconnected.

link cable is not connected.
[4] When multiple controllers are linked together, the same number is
set by mistake on two or more ADRS switches.
Action: [1] Check if the RDY lamp on the controller is lit. If the lamp is not lit,
the controller is faulty.
