5th to 10th Most Recent
Fault
Displays the fifth to the tenth most recent faults.
After ten faults have occurred in the drive, 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 every
time a fault occurs.

Cumulative Operation
Time
Displays the cumulative operation time of the drive. 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 Up/Down command is present. The
maximum number displayed is 99999, after which the value is reset to 0.

Cooling Fan Operation
Time Displays the cumulative operation time of the cooling fan. The default value
for the fan operation time is reset in parameter o4-03. This value will reset to 0
and start counting again after reaching 99999.
