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
(4CH)
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 Run command is present.
The maximum number displayed is 99999, after which the value is reset to 0.
