First to 49th
Most Recent
Fault
Displays the 1st to the 49th most recent faults.
After 49 faults have occurred in the drive, the 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: Maintenance Monitors
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 ON.
The maximum number displayed is 99999, after which the value is reset to
0.
