*1. Values shown are for 200V class inverters; double values for 400V class inverters.
*2. High-speed motor (operation frequency > 400Hz) is not supported above 40HP.
‡
Select high starting torque only for the following conditions.
(1) The power cable length is > 150m (492ft).
(2) Voltage drop at startup is high.
(3) An AC reactor is used on the input side or output side of the inverter.
(4) Motor power lower than the inverter rated power.
