U3-05 to
U3-10
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.

U4-01
<41>
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.

U4-03
<42>
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.
No signal output
available
1 h
U4-04
Cooling Fan
Maintenance
Displays main cooling fan usage time in as a percentage of its expected
performance life. Parameter o4-03 can be used to reset this monitor. The fan
should be replaced when this monitor reaches 90%.
