<1> Display is in the following units:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 A units
2o0054 to 2o0248 and 4o0034 to 4o0720: 0.1 A units
4o0900 and 4o0930: 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.
<4> In V/f and V/f w/PG control modes, 10 V = default value of E2-11. In OLV, CLV control modes, 10 V = setting value of E2-11 (kW). OLV/PM,
AOLV/PM, and CLV/PM control modes, 10 V = setting value of E5-02.
<5> Display is in the following units:
2o0028, 2o0042, and 4o0011 to 4o0027: 0.01 kW units
2o0054 to 2o0248 and 4o0034 to 4o0930: 0.1 kW units
