Output Current
Shows the actual output current.
The keypad shows the value of U1-03 in amperes (A). When
looking at the monitor through MEMOBUS/Modbus
communications, the current is “8192 = drive rated current (A).”
Calculate the current from the monitor value that is in at
MEMOBUS/Modbus communications using “Numerals being
displayed / 8192 × drive rated current (A).”
Unit: Determined by the drive model.
• 0.01 A: 2004 to 2042, 4002 to 4023
• 0.1 A: 2056 to 2415, 4031 to 4675

Output Power
Shows the internally-calculated output power.
Changing the setting of A1-02 [Control Method Selection] also
changes the signal level of the analog output.
• A1-02 = 0, 1 [V/f Control]: Drive capacity (kW)
• A1-02 = 2 to 8 [Vector Control]: Motor Rated Power (kW) [E2-
11]
Unit: Drive capacity and C6-01 [Normal / Heavy Duty Selection]
calculate the maximum applicable motor output.
• Less than 11 kW (15 HP): 0.01 kW
• Less than 11 kW (15 HP): 0.1 kW
