9 Troubleshooting
Remarks
Check that communication ca-
bles are correctly connected to
connectors.
Check that the wiring of commu-
nication cables is correct.
Check that the Master Unit is
correctly operating. If using an
OMRON Master Unit, check the
Master Unit mode and the node
address-setting ID switches of
the inverter.
If the Master Unit is made by an-
other manufacturer, refer to the
instruction manual for that prod-
uct.
When there are devices in the
surrounding area that generate
noise, adopt measures against
noise for the Master Unit, inver-
ter and communication cables.
Check that the inverter power
supply is being supplied normally
(for example, the main power
supply of the inverter is wired
correctly, the power supply volt-
age has not dropped, and inver-
ter operation is normal).
Remove the cause of the abnor-
mality and turn the inverter pow-
er supply OFF then back ON
again.
A slave initialization error occur-
red in the master.
Replace the inverter.
Is cable length appropriate (max.
100 m)?
Is the cable disconnected or
loose?
Is there a lot of noise?
