<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)".
