If the disconnection due to the Bus-Off signal
or timeout occurs during the operation using
DeviceNet commands, the inverter will shut
off its output and display the error code

(The inverter will trip according to the
settings of "p45" and "P048".) Check whether the communication speed
setting is correct.
Check whether the wiring distance is
appropriate.
Check the connections. Refer to the
instruction
manual for
the SJ-DN.
Duplicate MAC

If two or more devices having the same MAC
ID are detected in the same network, the

If the Force Fault/Trip bit of Attribute 17 in
the Instance 1 of the Control Supervisory
object is set to "1", the inverter will shut off
its output and display the error code shown
on the right. Check whether the Attribute 17 in the
Instance 1 of Class 29 is "1". (If so, clear the bit
