■ o4-09: IGBT Maintenance Setting
Sets the value of the IGBT maintenance time displayed in U4-07 as a percentage of the total expected performance life.
This value should be reset to 0 when the IGBTs have been replaced.
Note: The actual maintenance time will depend on the environment where the drive is used.
■ o4-11: U2, U3 Initialization
When the drive is initialized, the fault trace and fault history monitors (U2- and U3-) are not reset. Parameter
o4-11 can be used to reset them.
Setting 0: No action
The drive keeps the record already saved concerning fault trace and fault history.
Setting 1: Reset fault data
Resets the data for the U2- and U3- monitors. Once o4-11 is set to 1 and the ENTER key is pressed, fault data is
erased and the display returns to 0.
■
o4-12: kWh Monitor Initialization
The kWh monitors U4-10 and U4-11 are not initialized when power is shut off or the drive is initialized. Use o4-12 to
manually reset them.
Setting 0: No Action
The kWh data are kept as they are.
Setting 1: Reset kWh Data
Resets the kWh counter. The monitors U4-10 and U4-11 will display “0” after they are initialized. Once o4-12 is set to 1
and the ENTER key is pressed, kWh data is erased and the display returns to 0.
■
o4-13: Number of Run Commands Counter Initialization
The Run command counter displayed in U4-02 is not reset when the power is cycled or the drive is initialized. Use o4-13
to reset U4-02.
