6.2.2 Troubleshooting
x Condition: Communication cannot be performed properly!
Follow the flowchart to identify the applicable cause and check the corresponding action specified in a
box.
ż=YES, ×=NO
The details of each [Check] item accompanied by an asterisk (*) are explained at the end of the flowchart.
Was communication okay before?
Communication disabled with all controllers?
Communication is disabled
with all controllers o [1] Faulty host or X-SEL o [Repair the host or X-SEL]
[2] Open communication cable or poor contact due to vibration,
etc. o [Repair the open cable]
[3] Cable breakage on DeviceNet communication power supply
(24V) (Fieldbus type) o [Repair the open cable]
Communication is disabled
with a certain controller o [1] Faulty controller o [Replace]
[2] Open communication cable between the controller and
junction o [Repair the open cable]
[3] Detached terminal resistor o [Install the resistor again]
[4] Invalid setting of controller axis No.
(Controllers have been swapped, parameters were
initialized, controller software was updated, etc.)
o [Check] *3
[5] Invalid setting of controller baud rate
(Controllers have been swapped, parameters were
initialized, controller software was updated, etc.)
o [Check] *4
[6] Invalid setting of transmitter activation time
(Controllers have been swapped, parameters were
initialized, controller software was updated, etc.)
o [Check] *4
[7] Operation mode is set to MANU Mode on the controller.
o [Switch over to AUTO Mode]

Communication cable partially movable?
The cable is partially movable o Open communication cable o [Repair the open cable]
Power-supply voltage to each device appropriate? (Each RC controller, SIO converter, etc.)
Abnormal power-supply voltage o [Correct the power-supply voltage]
Problem occurred after change in surrounding environment? (Change regarding a nearby device, etc.)
Problem occurred
after a change
o [[1] Check if the wiring route of the communication cable has been
changed] *5
[[2] Check if each RC controller is connected to the FG terminal] *5
[[3] Install a clamp filter in the power supply line]
[[4] Check the grounding of the control panel] *5
o Malfunction due to noise
