Fault display
Probable cause and remedy
Warning name and meaning
oH3
Inverter overheating warning (oH3)
An Inverter overheating warning signal
was input from an external control
terminal set to multi-function input.
•
Clear the Inverter overheating warning signal.
•
Eliminate the cause of the warning signal input.
CE
Communications time over (CE)
RS-422 or RS-485 communications
were not properly carried out within
2 s. (Detected when n151 is set to
“3.”)
•
A short-circuit, ground fault, or disconnection has
occurred on the communications line.
→
Check and correct the line.
•
The termination resistance setting is incorrect.
→
In the case of RS-422 communications, set
pin 1 of SW2 of all Inverters to ON. In the
case of RS-485 communications, set pin 1 of
SW2 of only the Inverter located at each end
of the network to ON.
•
Noise influence.
→
Do not wire the communications line along
with power lines in the same conduit.
→
Use the twisted-pair shielded wire for the
communications line
,
and ground it at the
Master.
•
Master’s program error.
→
Check and correct the program so that
communications will be performed more than
once every 2-s period.
•
Communications circuit damage.
→
If the same error is detected as a result of a
self-diagnostic test, change the Inverter.
