<19> This value's number of decimal places depends on the drive model. The value will have two decimal places (0.01 A) if the drive model is
CIMR-E2A0004 to 2A0040, 4A0002 to 4A0023 and one decimal place (0.1 A) if the drive model is CIMR-E2A0056 to 2A0415, 4A0031
to 4A1200.
<50> When reading the value of this monitor via MEMOBUS/Modbus a value of 8192 is equal to 100% of the drive rated output current.

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