Message
Displays the fifth to the tenth most recent faults.
After ten faults, data for the oldest fault is deleted. The most recent fault
appears in U3-01, with the next most recent fault appearing in U3-02. The
data is moved to the next monitor parameter each time a fault occurs.

Elapsed
Time
Displays the cumulative operation time of the converter. The value for the
cumulative operation time counter can be reset in parameter o4-01. Use
parameter o4-02 to determine if the operation time should start as soon as
the power is switched on or only while the Run command is present. The
maximum number displayed is 99999, after which the value is reset to 0.
