Harmonic Corrective Actions DC Reactor Optional
<1> The motor capacity (kW) refers to a Sumitomo 4-pole motor. The rated output current of the drive output amps
should be equal to or greater than the motor rated current.
<2> Input current rating varies depending on the power supply transformer, input reactor, wiring conditions, and
power supply impedance.
<3> Rated motor capacity is calculated with a rated output voltage of 440 V.
<4> Carrier frequency is set to 2 kHz (Swing PWM). Current derating is required in order to raise the carrier frequency.
<5> Carrier frequency is set to 8 kHz. Current derating is required in order to raise the carrier frequency.
<6> DC is not available for UL standards.
