<1> Display is in the following units:
2A0004 to 2A0040, 4A0002 to 4A0023, and 5A0007 to 5A0017: 0.01 A units.
2A0056 to 2A0415, 4A0031 to 4A0675, and 5A0022 to 5A0242: 0.1 A units.
4A0930 and 4A1200: 1 A units.
<2>
The values of U1-03, U2-05, and U4-13 are displayed on the digital operator in units of amperes. When those monitors are checked using
MEMOBUS/Modbus communications, the monitor values in MEMOBUS/Modbus communications are displayed as: numeric value / 8192 × drive
rated current (A) from the condition “192 (maximum value) = drive rated current (A)”
<3> Values shown are specific to 200 V class drives. Double the value for 400 V class drives. Multiply the value by 2.875 for 600 V class drives.
<4> In V/f and V/f w/PG control modes, 10 V = drive capacity (kW). In OLV, CLV, OLV/PM, AOLV/PM, and CLV/PM control modes, 10 V = motor
rated power (E2-11) (kW).
