<18> Values shown here are for 200 V class drives. Double the value when using a 400 V class drive.
<19> Display is in the following units.
CIMR-A2A0004 to 2A0040, CIMR-A4A0002 to 4A0023: 0.01 A units
CIMR-A2A0056 to 2A0312, CIMR-A4A0031 to 4A0675: 0.1 A units
CIMR-A4A0930 to 4A1200: 1 A units
<22> The display resolution depends on the rated output power of the drive after the Drive Duty has been set in parameter C6-01. Drives with a
maximum output up to 11 kW will display this value in units of 0.01 kW (two decimal places). Drives with a maximum output greater than 11
kW will display this value in units of 0.1 kW (one decimal place). Refer to Model Number and Nameplate Check on page 32 for details.
<23> 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/Modbus communications, the monitor value in MEMOBUS/Modbus communications is: displayed numeric value
/ 8192 drive’ rated current (A), from the condition “8192 (maximum value) = drive’ rated current (A)”
<60> In V/f and V/f w/PG control mode, 10 V = drive capacity (kW). In OLV, CLV, OLV/PM, AOLV/PM, or CLV/PM control mode, 10 V = motor
rated power (E2-11) (kW).
