This is an operation pattern of which the starting characteristic such as the fan and pump is suitable for the load of
double reduction type. Choose from Square 1 and 2 according to the starting characteristic.
Square 1: Voltage is produced in proportion to 1.5 times the frequency.
Square 2: Voltage is produced in proportion to twice the frequency. This is used for variable torque(VT) load(fan,
pump) of the fan or pump.
