<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)".

Description
All Modes
Displays the DC bus voltage at the previous fault.
All Modes
Displays the output power at the previous fault.
V/f OLV
Displays the torque reference at the previous fault.
All Modes
Displays the input terminal status at the previous fault. Displayed as in U1-10.
All Modes
Displays the output status at the previous fault. Displayed as in U1-11.
All Modes
Displays the operation status of the drive at the previous fault. Displayed as in U1-12.
All Modes
Displays the cumulative operation time at the previous fault.
All Modes
Displays the run speed after a soft start when a previous fault occurred. Displayed as in U1-16.
V/f OLV
Displays the q-axis current for the motor at the previous fault. Displayed as in U6-01.
V/f OLV
Displays the d-axis current for the motor at the previous fault. Displayed as in U6-02.
All Modes
Displays the temperature of the heatsink when the most recent fault occurred. Displayed as in
U4-08.
All Modes
Displays the peak current that occurred just prior to the previous fault.
All Modes
Displays the output frequency when the peak current displayed in U2-21 occurred.
Description
All Modes
Displays the first to the fourth most recent faults.
All Modes
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.
All Modes
Displays the cumulative operation time when the first to the fourth most recent faults occurred.
All Modes
Displays the cumulative operation time when the fifth to the tenth most recent faults occurred.
