<10> The display resolution depends on the rated output power of the drive. Models CIMR-LU20008 to 20033, 40005 to 40018, and
50003 to 50013 display values in 0.01 A units, while models CIMR-LU20047 to 20415, 40024 to 40605, and 50017 to
50200 display values in 0.1 A units.
<29> Setting units are determined by the digital operator display unit selection (o1-03). When o1-03 = 0, the value is set in Hertz. When o1-03 = 4
or 5, the value is displayed in m/s. When o1-03 = 6, the value is displayed in ft/min.
<40> When checking the values of U1-03, U2-05 and U4-13 with the digital operator they are displayed in units of amperes, but when they are
checked using MEMOBUS communications, the monitor value in MEMOBUS communications is: displayed numeric value / 8192 × drive’s
rated current (A), from the condition “8192 (maximum value) = drive’s rated current (A)”.

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.
