Notes MMMM Application of Inverter Selection ■ Inverter Capacity Use a DC reactor or AC reactor (option) on the inverter 4000 input side when the inverter is connected directly to a largeDC or AC reactor required capacity power transformer (600 kVA and more within 10 m DC or AC reactor distance) or when a power factor improvement capacitor is 600 not required switched. Otherwise excess peak current may occur in the （kVA） power feed circuit and the converter section may be 0 60 400 damaged.
PAGE 94
■ Installing a Ground Fault Interruptor or an MCCB Be sure to install an MCCB or an ELCB that is recommended by Yaskawa at the power supply side of the drive to protect internal circuitry. The type of MCCB is selected depending on the power supply power factor (power supply voltage, output frequency, load characteristics, etc.). Sometimes a fairly large MCCB may be required due to the affects of harmonic current on operating characteristics.
PAGE 95
■ Power-factor Improvement (Elimination of Phase Advance Capacitor) , To improve the power-factor, install an AC reactor or DC reactor on the inverter s primary side. DC reactor is built in 18.5 to 110 kW, 200 V class inverters and 18.5 to 300 kW, 400 V class inverters. Power-factor improvement capacitor or surge suppressors on the inverter output side will be damaged by the harmonic component in the inverter output.
PAGE 96
Application of Motors Application to Existing Standard Motors ■ Low Speed Range A standard motor driven by the inverter generates slightly less power than it does when it is driven with commercial power supply. Also, the cooling effect deteriorates in low speed range causing a motor temperature to rise. Therefore, reduce load torque in the low speed range. Allowable , load characteristics of Yaskawa s standard motor are shown in the figure.
PAGE 97
Application to Special Purpose Motors ■ Pole Change Motors Select the inverter with a capacity exceeding the rated current of each pole. Pole change should be made after the motor stops. If a pole is changed while the motor is rotating, the regenerative overvoltage or overcurrent protection circuit is activated and the motor then coasts to a stop. ■ Submersible Motors Since the rated current of underwater motors is large compared with general purpose motors, select an inverter with a larger capacity.

Power Transmission Mechanism（Gear Reduction, Belt, Chain, etc.） When gear boxes and change/reduction gears lubricated with oil are used in power transmission systems, continuous low speed operation decreases the benefits of oil lubrication function. Also, operation at more than 60 Hz may result in noise, reduced life, etc.
