Description<br />
If the disconnection due to the Bus-Off<br />
signal or timeout occurs during the<br />
operation using DeviceNet commands,<br />
the inverter will shut off its output and<br />
display the error code shown on the right.<br />
(The inverter will trip according to the<br />
settings of "p45" and "P048".)<br />
If two or more devices having the same<br />
MAC ID are detected in the same<br />
network, the inverter will display the error<br />
code shown on the right.<br />
If the Force Fault/Trip bit of Attribute 17 in<br />
the Instance 1 of the Control Supervisory<br />
object is set to "1", the inverter will shut<br />
off its output and display the error code<br />
shown on the right.<br />
If timeout occurs during the<br />
communication between the inverter and<br />
DeviceNet option board, the inverter will<br />
shut off its output and display the error<br />
code shown on the right.<br />

Troubleshooting and corrective action<br />
Check whether the communication speed<br />
setting is correct.<br />
Check whether the wiring distance is<br />
appropriate.<br />
Check the connections.<br />
Check whether duplicate MAC IDs are<br />
used.<br />
Check whether the Attribute 17 in the<br />
Instance 1 of Class 29 is "1". (If so, clear<br />
the bit to "0".)<br />
Check whether the option board has been<br />
disconnected from the inverter.<br />

the SJ-DN.<br />
Note: If the option board does not operate normally, confirm the DIP switch settings on the option board.<br />

MAC ID<br />
Dip switch setting<br />
The left-most switch indicates the highest-order bit of MAC ID. Therefore, the<br />
example of switch settings shown on the left indicates the following MAC ID:<br />
= 29 (hexadecimal) = 41 (decimal)<br />
Note: For details, refer to the instruction manual for the option board.<br />
