<1> Assumes operation at the rated output current. Input current rating varies depending on the power supply transformer, input reactor, wiring
connections, and power supply impedance.
<2> Rated input capacity is calculated with a power line voltage of 480 V × 1.1.
<3> The rated output current of the drive output amps should be equal to or greater than the motor rated current.
<4> Carrier frequency is set to 4 kHz for models CIMR-U40011 to 40414. Carrier frequency is set to 3 kHz for models CIMR-U40477
to 40930. Current derating is required in order to raise the carrier frequency.
<5> If the harmonic current distortion is needed to be 5% or less, the maximum output voltage will be the equivalent to the input voltage × 0.87.
C7-60 (Output Voltage Limit Mode Selection) is needed to be changed from the default setting.
<6> User-adjustable
<7> Use a stand-alone EMC filter with a voltage of 380 to 480 V for models CIMR-U40477 to 40930.
