Multiple rating setting
Two rating types of different rated current and permissible load can be selected. The optimal inverter rating can be selected
according to the application, enabling equipment to be downsized.
*1 Available for the three-phase power input model only.
 Changing the parameter initial values and setting ranges
• When inverter reset and all parameter clear are performed after setting Pr.570 , the parameter initial values are changed
according to each rating, as shown below.
*1 Initial values differ depending on the rating as follows.
*2 The rated current and motor capacity values differ depending on the inverter capacity. Refer to the inverter rated specifications in the Instruction
Manual (Connection).
