b)
Since the latest fault content data are stored in the inverter, even if the power supply is turned off,
they can be monitored after the power supply is turned on again
(1)
Checking fault contents
The latest data are stored in the constant (Pn-48). (except UV)
(2)
Clearing fault contents
The contents are cleared by setting “6” to the constant (Pn-00). Or they are also cleared by
constant initialization.
[Set constant (Pn-00)=8 or9.]
At this time, other constants are changed to the factory setting values. Therefore, record all of the
constant data before initializing constant.
(3)
Faults to be stored
OC(overcurrent), OV(overvoltage), OH(cooling fin overheat), OL1(motor overload),
OL2(inverter overload), OL3(overtorque detection), EF4, EF5(external fault), CPF05(AD
converter fault).
For details, refer to Table 1.8 “Fault Display and Contents” on page 27.
