(2) Values of "Ki (conversion factor)"
Depending on whether an optional ACR (AC reactor) or DCR (DC reactor) is used, apply the
appropriate conversion factor specified in the appendix to the guideline. The values of the conversion
factor are listed in Table B-3.

Main applications
w/o a reactor K31 = 3.4 • General-purpose
inverters
w/ a reactor (ACR) K32 = 1.8 • Elevators
w/ a reactor (DCR) K33 = 1.8 • Refrigerators, air
conditioning

w/ reactors (ACR and DCR) K34 = 1.4 • Other general
appliances
Some models are equipped with a reactor as a standard accessory.
[2] Calculation of Harmonic Current
(1) Value of "input fundamental current"
• When you calculate the amount of harmonics according to Table 2 in Appendix of the Guideline, you
have to previously know the input fundamental current.
• Apply the appropriate value shown in Table B-4 based on the kW rating of the motor, irrespective of the
inverter type or whether a reactor is used.
If the input voltage is different, calculate the input fundamental current in inverse proportion to the
voltage.
