Monitoring of Fault Contents
If a fault occurs, the fault contents are displayed with priority over
other display items. Press the >/RESET Key or turn on the fault
reset signal to reset the fault.
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.
•Checking fault contents
The latest data are stored in the constant No. 48. (except uU)
•Clearing fault contents
The fault contents alone can be cleared by setting the value of
constant No. 00 to 6. The fault contents will also be cleared
when constants are initialized by setting constant No. 00 to 8 or
9. Other constants will also be initialized, so record the con-
stant data before initialization.
•Faults to be stored
OC (overcurrent), OV (overvoltage), OH (cooling fan over-
heat), OL1 (motor overload), OL2 (Inverter overload), OL3
(overtorque detection), EF4, EF5 (external fault), CPF05 (AD
converter fault).
