(*1) 4-pole standard motor
(*2) Rated capacity is calculated by assuming the output rated voltage as 230 V for 230 V series and 460 V for 460 V series.
(*3) Output voltage cannot exceed the power supply voltage.
At single-phase input use, the output voltage may be lower than three-phase input.
(*4) Voltage unbalance [%] = (Max. voltage [V] - Min. voltage [V])/Three-phase average voltage [V] ×67(See IEC61800-3.) If this value is 2 to 3%, use an optional AC reactor (ACR).
(*5) Required when a DC reactor (DCR) is used.
(*6) Without external braking resistor condition. Average braking torque for the motor running alone. (It varies with the efficiency of the motor.)
(*7) For inverters of 100HP or above, the DC reactor is provided as separate standard component. Be sure to connect it to those inverters.
