(1) Values shown are for nominal input voltage, drive carrier frequency of 2 kHz or as shown and surrounding air temperature at the motor of 40 °C. Consult factory regarding operation at carrier
frequencies above 2 kHz. Multiply values by 0.85 for high line conditions. For input voltages of 380, 400 or 415V AC, multiply the table values by 1.25, 1.20 or 1.15, respectively.
(2) These distance restrictions are due to charging of cable capacitance and can vary from application to application.
(3) Includes wire in conduit.
(4) A 3% reactor reduces motor and cable stress but can cause a degradation of motor waveform quality. Reactors must have a turn-turn insulation rating of 2100V or higher.
