Parameters for energy-saving control functions are shown in the following table.
*1.The factory setting is 1.0 when using V/f control with PG.
*2.The factory setting is 2.00 s when Inverter capacity is 55 kW and over.
*3.The same capacity as the Inverter will be set by initializing the parameters.
*4.The factory settings depend on the Inverter capacity.
