Monitoring Faults:
(From Yaskawa inverter handbook page 8-3)

When a problem occurs, an alarm is displayed in the 1-line display. The previous fault data is stored in the inverter so that you can look at it, even after the power supply is turned off and turned on again. The previous fault message is stored by no-48. Follow this procedure to display the most recent fault generated

The following messages are always stored, even after the power is turned off and turned on again.

Alarm (fault type) stored after they occurred:
 

Fault	What it means
oC	Over-current
ou	Over-voltage
oH	Cooling fin over-heating
oL1	Motor overload
oL2	Inverter overload
oL3	Over-torque detection
EF4	External Fault
EFF5	External Fault
CPF05	AD converter fault

Clearing Faults:

The fault content can be cleared by setting no-00 to 6.
-or-
Fault can be cleared by initialisation which means you have to set no-00 to 8 or 9.

Please remember that initialisation, also resets all constants to their factory settings.
